FOREWORD The Ministry of Education acknowledges that the learner performance in the areas of Mathematics requires urgent attention. In 2003 a small group of educators participated in a Study Tour visiting schools in Honduras where the Interactive Radio Instruction was practiced. The findings revealed that the methodology is workable, and most important, it is ‘learner friendly’. During 2006 the Interactive Radio Instruction was aired for Primary school teachers, learners and school communities to become familiar and sensitized to the elements of the programme. The momentum has been constructed, the teachers are eager, the first graders are ready. The success of the Interactive Radio Instruction programme depends entirely on continuous high level supervision by Headteachers and the teachers ensuring that the learners are on task. The importance of follow-up work and practice exercises must be emphasized, if a high degree of success is to be measured. Commendation is extended to the entire team who dedicated their time and talent to the development, design and testing of this strategy. Thanks to the Government of Guyana and the Inter-American Development Bank for placing their seal of approval on this significant programme which will have powerful dividends for this cohort and generations to come. Parents, teachers and learners, “tune in”, enjoy and learn from “The Land of Numbers” Geneveive Whyte-Nedd Chief Education Officer (ag.)

PREFACE

In 2005 Mathematics was introduced at Grade 1 into the curriculum and the performance of children has shown significant improvement. The various components of IRI methodology support the classroom effort of teachers in that they are provided with basic initial training for using the methodology supported by a Teacher’s Manual and Pupil’s Worksheets. There is also a programme offering classroom support to teachers by Mathematics Specialists, and opportunity to provide the radio production teams with regular feedback. Such feedback is necessary for continuous improvement of the materials presented. IRI Mathematics commences at Grade 1 and is now at Grade 2. Next year it will be at Grade 3. The methodology involved has great potential and promise that could positively affect other subjects of the curriculum provided that educators, teachers, parents and pupils continue with their enthusiasm as we move towards sustaining this methodological approach in instructional design. Best wishes,

OVERVIEW: TEACHER’S GUIDE FOR “THE LAND OF NUMBERS” GRADE 2 IRI MATHEMATICS – TERM 1 This Guide is for you, teacher of Grade 2. It will guide you in implementing the method called Interactive Radio Instruction - IRI - when you are teaching Mathematics to Grade 2 children. As teachers, we know that there are different ways of teaching, some more effective than others. Some may require more resources (e.g. books, worksheets) or may be more appropriate for a particular subject than others, while other techniques are more appropriate for a particular environment (big classrooms, tables, chairs, or corners for reading, etc.). Interactive Radio Instruction (IRI) is the name given to a particular educational method that uses radio for effective learning. IRI emphasizes active learning and meaningful interaction between the radio characters and the teacher and pupils. This particular method is used in the school to support you in your quest to provide quality Mathematics learning for Guyanese children in Grade 2. One hundred thirty–three IRI lessons will be delivered to Grade 2 teachers and pupils through broadcasting or CDs of a series of programmes called “The Land of Numbers”. Each lesson lasts approximately 50 minutes and is divided into two parts. The first part is AUDIO and the duration 28 minutes and the second part is FACE-TO-FACE interaction between the teacher and the pupils without audio and lasts 20 minutes. Both parts contain guided, engaging activities for teaching and learning Mathematics. The main purpose of these one hundred thirty-six IRI lessons is to provide an opportunity to the children of Grade 2 to develop their abilities in Mathematics according to the mathematical standards for this grade. A Teacher’s Guide is provided to support you during both portions of each lesson.

1. THE EFFECTIVENESS OF TEACHING WITH IRI The children who participate in IRI lessons will learn Mathematics because of the carefully planned combination of audio technology and the role of the classroom teacher. The classroom teacher facilitates the process of learning, encourages the children and works with each of them, giving special attention to those who needs it. The order of the activities or exercises and the amount of practice are carefully planned in both the audio and the face-to-face formats to provide the most effective instruction possible. An important reason why children learn so much is that the broadcast or audio section is carefully designed so that children actively participate. The radio teacher and other characters speak directly to the children. The children respond orally, by writing, drawing simple pictures, using counters (pebbles), singing and so on. As you know, teacher, children like to be active, and as a result they will also enjoy the lesson and listen attentively to the Audio Programme. Children like to do the mathematical activities and sing the songs (see the song lyrics for Grade 2 at the end of this Guide), riddles, tongue twisters and physical activities which are included within the educational segments in each broadcast or Audio Programme. On average, children answer questions or perform some other activity every 20 seconds. The activities and learning situations designed for the face-to-face portion (the After-Audio Programme) are also carefully planned and will help you build on what the pupils have learned during the Audio Programme. Although each After-Audio Programme activity is carefully planned, it is up to you, the teacher, to lead these activities with your pupils.

2. ELEMENTS OF THE IRI FOR MATHEMATICS CLASSROOM The IRI Mathematics programme is planned to ensure that you, teacher, have everything you need to teach your pupils effectively. It is important that you understand the following elements of the programme. 2.1 The IRI Mathematics curriculum is organised in a different way: The instructional material is selected and organised according to the abilities that the children will need to solve any particular exercise, activity or Mathematical problem, more than the mathematical content. The exercises or activities that support the development of these abilities can be found on the first page of each lesson under the heading “Part 1: During the Audio Programme” and the second page under the heading “Part 2: The After-Audio Programme". Teachers, however, can find mathematical topics organised by terms at the end of each Guide.

Another aspect of the development of the IRI curriculum for Mathematics is the selection of the mathematical terminology; which is also carefully planned. As teachers, we know that the terms we use during the process of teaching can make a significant difference in the process of learning, especially when teaching Mathematics. The characteristics of a good instructive message are brevity and clarity. Brevity maintains the rhythm of the interaction while Clarity uses simple and direct language, which avoids confusion. As you follow the Audio Programmes for some time, you will become accustomed to the way the instructions are structured and organized, how the Mathematics curriculum is presented across the 136 IRI lessons, and the language that is used to instruct. The selection of the mathematical terminology such as “numeral”, “number”, “digit”, “cardinal”, “ordinal”, “greater than”, “less than”, “greatest”, “least”, etc. or symbols such as +, - , =, <, > are also carefully planned. You will find that the use of some mathematical terminology, such as numeral, is postponed to a higher grade, but this does not mean that children will not realise or learn the difference between a name given to a quantity, e.g. “FIVE” and the written symbol, such as “5”. The development of the Mathematics curriculum that applies to the Interactive Radio Instruction ensures that children apply well the names that they are learning to the observed magnitudes and use the convenient term for the actions or operations they do. 2.2 Coverage of Mathematics Content in IRI Mathematics: Scheduling for full coverage of the curriculum during the school hours is always a challenge for us, teachers. Sometimes, at the end of the school year, you may find that there are still many areas or topics of the curriculum that need to be covered, or maybe some important topics were left out. This, understandably, may worry you, parents, educational authorities and others. The way the IRI curriculum is designed and the time assigned to each lesson (50 minutes) ensures that the children will cover close to 100% of the mathematical content selected for this grade and develop their mathematical abilities to achieve the standards for this grade. You will find a useful resource in this Guide that will help you understand how the mathematical topics for Grade 2 are covered. At the end of the Teacher’s Guide for each term, we have included a chart displaying the distribution of Mathematics topics across the 136 IRI Mathematics lessons.

Basic materials for children. The following are basic materials that the pupils will need:

 Chequered-line exercise books: A chequered-line exercise book has pages with small squares. These little squares should facilitate the pupils’ writing and calculating processes. Pupils can write each digit of a number in a little square or write an operations symbol such as plus (+) or minus (-) in each square. The children will also need to draw shapes and calculate the area of rectangles or squares using these small squares as non-standard units. For such tasks, the small squares can easily be counted to calculate the area or the perimetre of these shapes. This chequered-line book will also facilitate the drawing of bar graphs or pictographs as well as align numbers when children are learning ‘place value’ and performing ‘column addition’, ‘subtraction’ or ‘multiplication’. The children sometimes have difficulties in the use of a page of their chequered-line exercise books. For example, when first using the books, children may have questions about where to begin, where to end, and how to distribute the space on a page. You and the radio characters will provide guidance. The radio characters will use terms during the instructions that guide the pupils in using their exercise books, such as, ‘Write 5 in the tens column” , “draw a long line below those exercises”, “write 2 above the number 6 in the tens column”, “look at the first column” etc. It is important that pupils understand the meaning of the above terms. You, teacher, can help by taking a few minutes after the Audio Programme to clarify the terms that pupils did not understand during the Audio Programme.

The activities of the After-Audio Programme will also require the use of the exercise books by the pupils. This can be another opportunity to learn how to optimize the use of each page of the chequered-line books.

This is an example of one page from a real exercise book, with exercises completed by a Grade 2 pupil. The Ministry of Education will provide chequered-line exercise books for the children of Grade 2.  Counters. The IRI Mathematics lessons will also require you and the pupils to have counters. Counters will not be provided to you, but are objects that you and the pupils can easily collect. Counters can be a variety of things that the pupils can count, such as pebbles, bottle caps, sticks, etc. The After-Audio lessons will use many counters for estimation or counting in groups of ten’s, five’s, two’s, etc. Some, but not all, of the Audio lessons will also need counters. The number of counters needed for each child and for each Audio Programme that calls for them is mentioned in the Teacher’s Guide for each term.

IRI Mathematics Grade Two

“THE LAND OF NUMBERS”


Storing the Counters: It is recommended that the counters for each child be put in a little cloth pouch which is then placed in a box with the other pouches. Storing the counters in this manner can help you, teacher, make sure that counters are not lost, reduce the amount of space required, and minimize the time spent distributing and collecting counters.

 Other resources in the classroom. Besides using checkered-line exercise books and counters, the IRI Mathematics lessons require materials that teachers already have or can easily be made or found around the classroom, such as: a) For Geometry: Cardboard shapes in different sizes: Squares, rectangles, triangles, circles. Solids: Cubes, cuboids, cylinders, cones. b) For Measurement of Length: Rulers, metre sticks. c) For Measurement of Time: Analogue and digital clocks, calendars. d) For Measurement of Capacity: Bottles, cups, litre (with scale that shows half litre, one fourth litre). e) For Measurement of Weight/Mass: Kilogramme, half kilogramme, one-fourth kilogramme, gramme and balances. f) For Money: Coins and bills ($1, $5, $10, $20, $100, $500, $1000) (can be an imitation of them on regular paper) The lessons may also require materials that the children might already have, such as pencils and crayons. It is also helpful to enhance the classroom learning atmosphere by decorating the walls with numbers, drawings of shapes, posters with number squares, etc., or by creating specific learning corners (a store corner or a geometry corner where the children can design geometric shapes, etc.) and creating other materials that facilitate the process of learning for the children.

2.4 Basic materials for the teacher:  Radio/CD player and recorded CDs: Each school received radio/CD players. This is considered to be a very important tool for each teacher. The radio/CD player should be used only during the Audio Programme and stored away in a safe, dry place at all other times. The schools or classrooms that are able to tune in to a radio station and have good AM reception will receive the IRI Audio Programmes by broadcast, Monday through Thursday according to the time table. If you will receive the programme by broadcast, be sure to tune the radio to the correct frequency before the IRI lesson begins. The other schools or classrooms that do not have good AM reception will use CDs. Each CD contains thirteen (13) IRI Audio Programmes in MP3 format. Whether you receive the programme via broadcast or on CD, all Grade 2 Mathematics pupils will be listening to and following the same 28-minute programme on any given day. Please note that each school is provided with only one radio/CD player. Since the radio/CD player and CDs are very important tools for making IRI a success in your classroom, it is highly recommended that you read the manual that comes with the unit and coordinate its use with the teachers of Grade 1. You wil need to be sure that the CD player is in place and ready for each grade’s lesson each day and that someone is responsible for charging the batteries and for taking care of these materials.

 The Teacher’s Guide: The information provided to you in the teacher’s guide for each term is organised by lesson. For each day, the Guide provides you with critical information on what to prepare before the programme; what you and the pupils will do during the programme; and details on the activities designed for after the Audio Programme, including illustrations of activities and the time assigned to each activity. It is very important that you read the Guide for each lesson before the time for the lesson. By reading the Teacher’s Guide for each lesson ahead of time, you will be equipped with the information you need to successfully lead pupils through the activities during and after the Audio Programme.

2.5 Opportunities for teachers: One of the most important roles of a teacher is to create a stimulating learning environment for the pupils. The Teacher’s Guide for each term allows you, teacher, to optimize your time. Much of the planning for lessons is already done, allowing you to spend more time in reading the Guide and creating or re-creating the activities proposed for the After-Audio Programmes. With the help of the Guide, you will be able to focus the time you spend in preparing for each class to make sure that the Mathematics lessons are successful. The Interactive Radio Instruction (IRI) programme for Mathematics does not intend to create additional work for teachers but instead will help maximize the time teachers dedicate to their pupils. IRI for Mathematics also gives teachers an opportunity to develop competencies that they are usually not able to develop in a regular classroom. These include observing children as they complete various Mathematics activities during the Audio Programmes, providing focused attention to struggling pupils, and closely following the progress of the pupils. Through IRI, teachers will have the opportunity to improve these skills, among others. Weekly Reviews. The IRI Mathematics lessons incorporate a weekly review, which provides activities to be done each Friday for thirty minutes. You can also use this time to cater to the needs of the children, and provide 8 “THE LAND OF NUMBERS” IRI Mathematics Grade Two


additional practice in areas where they may be having difficulty. You are encouraged to observe the children during and after each Audio Programme and take notes to design or create review activities for the children or re-create the activities proposed according to the needs of your pupils. Each review activity is an opportunity to follow the progress of your pupils while also keeping a record for each pupil. Using this information, it will be easier for you at the end of each term to prepare a progress report for your students since you have been keeping track of their review activities throughout the term.  Observation in the IRI classroom: By observing your classroom during an IRI programme, you will be able to easily identify those children who are giving correct answers, writing well, using their fingers in the correct way to find the answers, using the counters appropriately, singing, and so on. As you observe your pupils on a daily basis you will also have the opportunity to identify how each of them approaches mathematical problems and be able to track their difficulties. With these improved skills, you will also be able to identify those pupils who may need special attention and prepare focused activities to help them improve in their difficult areas.

3. PARENTS AND TUTORS PLAY AN IMPORTANT ROLE IN IRI CLASSROOMS The school culture usually involves parents for specific purposes and during certain occasions. IRI Mathematics for Grade 2, through broadcast, also gives parents and the general community an opportunity to be involved in their children’s education in Mathematics. Where possible, parents and the community can be involved by turning their radios on to follow each IRI lesson as it is broadcast. By tuning in, parents will know what their children are learning every day in Mathematics and will also be able to provide support to them at home. Also at home, parents can be involved in their child’s progress by reviewing their exercise books and asking their children about their lessons. The exercise books are an important reflection of the pupils’ progress in Mathematics. To gather additional support from parents and the community, each school can also take the opportunity to help parents understand how IRI Mathematics works. This may lead parents to appreciate and provide further support to the efforts that the school is making to improve the quality of Mathematics teaching and learning for their children.

4. THE IMPORTANT ROLE OF THE TEACHER IN THE IRI CLASSROOM Any method, tool, material or concept that enters the classroom needs a teacher to put it into practice to ensure the effective learning of pupils. Your preparation before the programme, involvement and observations during the programme, and leadership during the After-Audio activities are key factors in making the lessons successful.

4.1 Before the Audio Programme: a) Copying the exercises on the chalkboard and exercise books The following boxes are examples of exercises from lesson 12 that the teacher needs to copy on the chalkboard. The children are instructed to copy only the exercises where the flower is.

Teacher, each IRI lesson will have boxes with exercises, similar to the example above. Most of the lessons will request you to copy the boxes with exercises on the chalkboard. Each box has a drawing that identifies the kind of exercises that go in that particular box. It is recommended that these exercises be copied the way they are in the boxes, in the order they are presented, but they can be increased in size in such a way that all the children of your class can see. IRI Mathematics Grade Two

“THE LAND OF NUMBERS�


The children will need to copy some exercises from the chalkboard. This task is very important and needs to be done before each IRI class begins. It is also important to take note of the time the children need to copy the exercises. This way you, teacher, can calculate the time you need to copy the exercises on the chalkboard and allow the children to copy them.

b) Getting all the materials required for the IRI lesson ready In this Guide, the materials needed for each lesson are listed under the heading “Before the Audio-Programme”. The list will allow you to prepare those materials ahead of time. Some of these materials can be used with the whole class and some by groups of children, but some materials are needed for each child. c) Having the CD player and CD with the respective lesson ready. Before the Audio Programme begins, be sure to set the dial in place if you are receiving the audio lesson by broadcast. For those schools with lessons on CDs, be sure to place the CD in the CD player and forward to the respective lesson. 4.1 During the Audio Programme: The radio characters guide the learning process of Mathematics during the first 28 minutes of each IRI lesson in the classroom. While pupils interact with the radio characters, the radio teachers, and each other, classroom teachers have an opportunity to pay attention to their children’s different paces of learning and give special support to those who need it. The teachers may also encourage the participation of each pupil and check the pupils’ work. Teachers can also participate in the singing and do the physical activities. For the children, the teacher is the most important person in the classroom, so children will constantly look to their teacher to provide the support and guidance they need. With your support, and by using the IRI Mathematics programme as your tool, children will improve their learning in Mathematics.

IRI Mathematics Grade Two

“THE LAND OF NUMBERS”


4.2 The After-Audio Programme: The Guide for each IRI lesson provides activities for the After-Audio Programme. Some of these activities complement the topics that are studied during the Audio Programmes, presenting them with different strategies. Other activities present topics that are not in the Audio Programmes (Geometry, basic Statistics, some topics of Measurement, estimation, etc.) but are necessary because they are part of the Mathematics Curriculum for Grade . Therefore, it is essential that you guide your pupils through the activities provided in the After-Audio lessons each day. You may also find the After-Audio time as an opportunity to create other activities or re-create the ones in this Guide to cater for the learning needs of your pupils. The description of each activity for after the Audio-Programme and each weekly review activity includes an approximate time of duration. The exact time required for each activity will depend on the rhythm of learning of each child and the whole class. It is highly recommended that you, teacher, take note of these times when preparing these activities. It is very important to have about 50 minutes of Mathematics class every day except Friday, which is dedicated to a 30-minute review of the week. The achievement of the Standards for Grade 2 requires this amount of time for Mathematics classes for the children. Please enjoy using IRI Mathematics as a tool to help you teach your Grade 2 Mathematics pupils. If you participate fully and use your creativity to implement the programme in the way most relevant to your pupils, we are confident that you will see progress in their learning and in the attitudes and participation in your Mathematics class.

Estimating Numbers (up to 20) 10 min  Place a bunch of sticks in front of the children. (no more than 10) Ask them: “How many sticks do you think there are in this bunch?”, “Are there more than 5?”, “More than 10?”, “How can we check it?” (Encourage the children to use various strategies, such as to hold the bunch in one hand and observing the space that it occupies to estimate the number of sticks).  Ask one child to count the bunch of sticks. Ask them: “How close were you?” “Were you nearly right?”  Change the number of sticks in the bunch. (no more than 20) and repeat the activity (let the children hold the bunch in one hand, look at it carefully, etc.)

Ask another group to count from 16 to 20 in the same way.  Explain to the children that this time they are going to count backwards. Begin with 20 to 15. Then ask one group to count backwards from 15 to 10. Another group can do the same from10 to 5.  Write the numbers on the chalkboard as shown in the box on the left. Then, as you point to each number, ask the children: “Are you adding ONE (1) every time you count on?” (10, 11, 12 etc.). “Are you taking away ONE (1) every time you count backwards?” (20, 19, 18 etc.)

*For the next lesson, you will need 30 counters or sticks.

Finding Answers to Column Addition  Tell the children to look at the chalkboard and find the exercises with the kitten. Tell the children to read the first exercise, aloud, as a group (five plus two). Ask “How much is five plus two?” (seven).  Tell the children to use their counters to verify their answer. Then ask one child to come to the front of the class and explain how he/she used the counters to verify their answer. Ask the rest of the class if they used their counters in the same way and, let some of them explain what they did. (see box for some examples)  Tell the children to copy the exercises into their books. Then, using their counters, tell them to find the answer to each addition exercise. Encourage them to work in groups. Recognizing an Open and a Closed Line 5 min  Teacher, you will need: Drawing of lines on the chalkboard. Some of them will be open lines, and others will be closed (see pictures in box).  Ask one child to come in front of the class and point to the “closed lines”. Ask the class: “Why are they called closed lines?” Ask him/her to trace one of the “lines” with their finger, marking the initial point where they started and see where the finger stops (same initial point). Explain this to the class.  Ask another child to point to the drawings with “open lines”. Ask the rest of the class to explain why they are “open lines”.  Then, allow the children to copy one “open line” and one “closed

line” in their notebooks using colours to distinguish a “closed line” from an “open line”. Ask each child to identify each line by writing “closed line” or “open line” below each drawing.

5 min

Describing the Use of Numbers ‘Outside of School’ (Homework)  Tell the children that when they are going home or when they are at home, they must look for objects that have numbers and take note of how those numbers are used in each of the objects. Encourage them to talk with somebody in their family about this.  Ask them to draw some of these objects in their exercise books, (one page) colour them and bring them for the next class. Lesson 3

Review of the Homework  Ask the children to show you their drawings of “Numbers Outside of School” and mark (sign) each of them.  Ask some of the children to explain one of her/his drawings. Ask him/her: “Which numbers appear in the object that you are showing?” “Can those numbers be changed?” Why or why not?”, “Can those numbers be placed in a different order?”, “Why or why not?” (e.g. in a watch, the position of the numbers cannot be changed; rulers, page numbers, calendar, money, etc.) Let the entire class participate in reading numbers and in the discussion.

5 min Colouring an Open and a Closed Line  Teacher, draw an open line and a closed line (see box) on the chalkboard.  Ask the children to draw both lines in their exercise books. Tell them to look at the two lines and tell you about them (what they look like? One is open and one is closed)  Ask them to move their finger around the edge of the open shape. Discuss how their finger stops when the line stops. Ask them to do the same with the closed shape; ask if their fingers have to stop?  Tell them to colour the shapes. Discuss what happens when they try to colour inside the open lines. 15

Recalling the Audio Characters of the Math Class  Teacher, you will need the list of the radio characters.  Have a discussion with the children about the radio lesson of this week and ask questions such us: - “Which of the radio characters (persons) is old?”, “Why do you think he or she is an old person?” - “How old do you think Number Seeka is?” (close to the children’s age) “and Amar and Lana?” (close to the children’s age). - “How many radio teachers are there?” (2) “What are their names?” (Ray, Leila).  Have the children draw a picture of the radio character that they like the most. They can also colour in their drawing and write the name of the character under it. Singing a Song and Identifying a Pattern  Teacher, you need the lyrics of the song: “The Magic Number is Two” on the chalkboard (see box). The way the song is presented and sung: chorus, verse, chorus, verse,… can be an example of a pattern.  Read the chorus with the children, and then read the verse. Ask the children: 5 min “Which part do you sing first?”, “Which part comes next?”, “… and next?” (chorus, verse, chorus, …). Ask them to see if they recognize a pattern and what they like most about this song.  End this activity by singing the song together.

Using the Checkered-line Exerecise Book  Teacher, as you already know, the children need to learn how to use the checkered-line book correctly, using the squares as a guide. It will be helpful to 5 min E W 1 practice how to do this. 3 1 5  Ask the children to get their exercise books and pencils ready.  Give the following instruction: (a) Write 11, leave a space, write 13, leave a space, write15. The children need to understand the meaning of “leave a space”, remembering not to write 1113 instead of 11 13. They can also use one little square to write each digit, and leave 2 squares space in between each number.  Then, ask the children to go down and (b) draw four marbles in a ROW. The children can use one little square for each marble and be sure that each marble is drawn side by side. Review 1

Review activities TEACHER: Facilitate the following activities Number Bonds of 10 10 min  Teacher, tell the children that they will use their fingers to find the answer to the following exercise: 6 +? = 10  Ask two children to show 10 fingers, and then put their hands down. Ask one of them to show any number of fingers that they wish to show (e.g.: 6 fingers). Tell the other child to show the number of fingers (e.g.: 4 fingers) that will make a total of TEN (10) fingers between the two children.  Emphasize that putting together the two groups of fingers gives the ten fingers.  Keep working this way with other pairs of children to make a total of 10 fingers between each pair.  Teacher, show the class “two fingers on one hand and one finger on the other hand” (while hiding all other fingers). Ask them: “How many fingers am I hiding”? (7) Continue with more exercises: showing 4 fingers with both hands and hiding 6; showing 2 fingers with both hands and hiding 8; showing 7 fingers and hiding 3. Singing the Song:  Tell the children you are going to review the song “I Would Fly”.  Read aloud the lyrics to the song for the children so that they are clear on all the words.  Ask them to sing the song with you.

……………………...

10 min Counting by Tens and Ones. Identifying the Ones.  Teacher, for this activity each child needs a pouch with 35 counters (or each group of children sitting together can use 35 counters). Explain that they are going to count their counters by “tens” and “ones”.  Tell the children to take away 35 counters and put them in a group. Observe whether the children are counting each counter one by one to have the group of 35 counters or if they are using different strategies.  Tell the children to put those counters (35) in groups of TENS.  Then ask them: “Are all your counters in a group of TEN?” (no) “How many groups of ten do you have?” (3) “How many counters are not in a group of ten?” (5)  With the children, count all the counters like this: TEN, TWENTY, THIRTY, THIRTY-ONE, THIRTY-TWO, THIRTY-THREE, THIRTY-FOUR, THIRTY-FIVE.

 Discuss with the children the strategies of “counting one by one” and “counting by tens and ones”. Ask “Which strategy is faster?”, “Which one is easier?”, “Why?”  Teacher, continue counting by ten’s and one’s: Ask the children to put 2 groups of ten counters and 2 loose counters on their tables. Ask them to 10 min count them (ten, twenty, twenty-one, twenty-two). Continue this way with 10 and 8, 20 and 9. Allow the children to go faster as they become comfortable counting by tens and ones. Colouring the Boundary and the Interior of a Shape (region)  Teacher, draw two shapes on the chalkboard (see box). While you draw these shapes on the chalkboard, ask the children to copy them into their notebooks.  Ask them to look at the boundary of the two shapes and tell you about them (what do they look like… both are closed).  Ask them to move their finger along the edge (contour) of the closed shapes. Discuss how their finger starts at “a point” and keeps moving until it reaches the same “point”, making a closed line.  For each shape, tell them to colour the boundaries (contour) of the shapes with one color and the interior with another colour.  Encourage them to write “boundary” (contour) and “interior” in the appropriate coloured parts of each shape For the next lesson, you will need 9 groups of 10 sticks each, and each child will need their pouch of counters (20 counters each).

PART 2: The After-Audio Programme TEACHER: Facilitate the following activities 10 min Colouring the Boundary and the Interior (inside) of a Shape (region)  Teacher, you will need: Shapes made of cardboard. They can be a square, a rectangle, a triangle and a circle.  Give each group of children ONE shape (square or rectangle or triangle or circle). Encourage each group to look at the shape, mark “a point” on the boundary (contour) and move their finger along the boundary, stopping at the point they marked (beginning “point”). Tell them to pass their hands by the interior of the shape and say the name of the shape.  Teacher, go around the groups and ensure the children are experimenting with the shape.  After a while, ask each child to make a drawing of the shape and colour its boundary and its interior using different colors. Ask them: “Is the boundary (contour) of that shape an open or closed line?”  Invite one child from each group to come in front of the class and show the boundary and the interior of their shape. Ask the child to give the name of the shape. Allow the other children to ask questions about each shape. 10 min Counting Objects or Counters by Tens and Ones  Teacher, have 9 bunches of ten sticks each ready on your table, in front of the class.  Explain that, as a group, you will count BY TENS the bunches of sticks as you show them, and then continue counting BY ONES with the help of the counters that each child has.  Begin with 30 and 8. You, teacher need to have 3 bunches of ten sticks and the children need to have 8 counters. Teacher, show them the bunch of sticks and count: Ten, twenty, thirty. Then ask each child to show one counter and say: Thirty-one. Next ask each child to show two counters and say: Thirty-two. Keep counting this way until you reach thirty-eight. End this 3exercise by asking: “How many counters do we have all together?” (38)  Explain to the children that you have the TENS and they have the ONES.  Continue counting this way with the following exercises: 60 and 9, 90 and 8, 70 and 6, 50 and 1 Copying Vertical Addition for Homework  Teacher, copy the following exercises on the chalkboard and ask the children to copy 5 min them into their exercises books to complete for homework: 24 46 + 15 + 32 For the next lesson, you will need 64 sticks.

PART 2: The After-Audio Programme TEACHER: Facilitate the following activities Checking the Homework (vertical addition) 5 min  Teacher, invite four children to show, on the chalkboard, their answers to the homework exercises. Ask them to show how they got each answer. While they explain, ask the rest of the class to correct their homework. Reading and Writing Numbers of Three DIGITS  Show the children the number flash cards, 3, 8 and 4 SIDE BY SIDE to make 10 min the number 384. Ask them to read the number (three Hundred Eighty-four). Teacher, make sure that children are not using the word “and” when reading.  Ask the children to write the number 384 in their exercise books. If the children are using chequered-line exercise books, make sure that each digit is written in a separate square. Discuss how the number “384” is written. Demonstrate on the chalkboard and explain how 384 520 712 993 384 is written (three, eight, four). When you read place emphasis on the word HUNDRED (three HUNDRED, eighty-four). 670 125 678 890  Ask the children to look at the number they have written and ask them: “How many DIGITS does 384 have”? (three digits)  Do the same for the remaining numbers in the box (see box). For each number, explain how each number is read and how it is written. Estimation and Counting by Tens and Ones to Verify  Have ready a bunch (group) of sticks or counters (no more than 64) and put 10 min them on a table in front of the class. Some of them can be in bunches of TEN sticks (e.g. 4 bunches of ten sticks each and 24 loose sticks).  Invite the children to look at the sticks or counters and THINK (guess) the number of sticks that are there altogether. Ask the children: “Do you think there are more than 5 sticks?”, “Are there more than 20 sticks?”, “Are there more than 100 sticks? Tell the children to write the number that they are thinking in their exercise books and to remember it. You may also write all their ‘guesses’ on the chalkboard.  Ask the children: “How can we check?” “Will it be faster to count one by one or by tens?” (As a group, decide how you will count the sticks, and if necessary, count using both ways).  Invite the children to count the sticks. (or counters) Write this number on the chalkboard.  Ask them: “How close were you?”, “Were you nearly right?” Change the number of sticks in the bunch or group (no more than 70) and repeat the activity. *For the next lesson, you will need the following shapes cut out of cardboard: rectangle, square, triangle, and circle.

Tell them to answer the following questions: “Do you have the 12 counters in a group (or row)?” “How many groups of TENS and ONES can you have with those counters?”  Encourage the children to show one group of tens and the two loose counters. Walk around the class to help students who need it. The counters may also be organized in rows.  Ask them again: “How many groups (rows) of tens and ones do you have?” Continue the same way with the following numbers of counters: 15, 18, 14, 17. Encourage the children to recognize the number of tens and ones by looking at and reading the numbers. Also encourage them to say how the numbers are written (12 is written “one, two”).

10 min Showing the Boundary, Interior (inside) and Exterior (outside) of a Shape (region)  Teacher, you will need: Shapes made of cardboard. They can be a square, a rectangle, a triangle and a circle.  Take one of the shapes (Triangle or Square or Rectangle or Circle) and show it to the class. Ask them to say the name of the shape.  Invite one of the children to come to the front of the class and show the BOUNDARY, the INTERIOR (inside) and EXTERIOR (outside) of the shape. Allow the other children to ask him/her questions about the shape and help the child to answer. Encourage them to use the words “boundary”, “interior”, “exterior”.  Continue the same way with the other shapes.  To close this activity, ask them: “Are the boundarys of these shapes ‘closed lines’?” (Yes)  Ask them to explain why they are closed lines. Ask “Can you colour the interior of each shape?” (yes) “What about the exterior?” (no boundary is showed and if they colour will not know where to stop). Allow them to explain why. Ask them to colour the shapes as homework. *For the next lesson, you will need 40 counters for each group of children, or a pouch of counters. Lesson 12 IRI Mathematics Grade Two

PART 2: The After-Audio Programme TEACHER: Facilitate the following activities 5 min Review of the Homework  Teacher, invite some of the children to come to the front of the class and share their drawings. Ask them to discuss how they coloured the boundary, interior and exterior of each shape. Allow the other children to ask questions to make sure they understand the concepts of “boundary”, “exterior” and “interior” related to a shape (region). Encourage the children to use these words when talking about their drawings.  While these children come to the front of the class, allow the rest of the class to correct their homework.

Grouping Objects (counters) in Tens and Ones 17  Teacher, ensure that each child has his/her pouch of counters. Ask them to put 10 min 17 counters in a group, close to them. OOOOOOOOOO  Ask the children: “Do you have the 17 counters in a group?”, “How many groups OOOOOOO of TENS and ONES can you have with those 17 counters?” Encourage the children to form 1of tens and 7 ones groups (rows) of tens and ones. Walk around the class to help any children who may need it.  Ask them again: “How many groups (rows) of tens and ones do you have?” (1 group of ten and two ones)  Continue the same way with the following numbers of counters: 18, 12, 19, 11. Encourage the children to identify the number of tens and ones present in each exercise, either by looking at the number, by reading it, or by saying how it is written. Making Patterns with Sounds 10 min  Ask the children to listen carefully to the following sound pattern: Make a sound with two sticks, making the same sound twice. Follow with a sound made by hitting one stick on the teacher’s table. Follow with the sound with two sticks again (twice), sound of one stick hitting the teacher’s table, … Stop suddenly and ask which sound would come next sound with two stick, (sound with the two sticks - twice). twice, sound with one  Ask one of the children to repeat the same sound pattern. Then ask the other children to stick on the table once, describe the pattern (sound with two sticks twice, sound with one stick on the table once). …  Ask each group of children to create one or two patterns using sounds using their hands, fingers, mouth or objects. Give them a few minutes for this, and walk around the class to help them.  Invite some of the groups to show the pattern they created. Allow the other children to ask questions about the pattern or describe the pattern. *For the next lesson, you will need 9 groups of 10 sticks ready. Lesson 13

5 min

Continue Adding Numbers Teacher, follow the instructions given by the radio teacher and solve the exercises with the chick. Keep Counting Counters by Tens and Ones (up to 99) 5 min  Teacher, each child should have 9 counters in front of them and you need to have 9 bunches of ten sticks each on your table, in front of the class.  Explain that all of you will count BY TENS the bunches of sticks that you will show them and continue counting BY ONES using the counters that each child has. Begin with 30 and 4. You, teacher need to have 3 bunches of ten sticks and the children need to have 4 counters. Teacher, show them the bunches of sticks and count: Ten, twenty, thirty. Then each child shows one counter and says: Thirty-one, shows two counters and says: Thirty-two keep counting until you reach Thirty-four. End this exercise by asking: “How many counters do we have all together?” (34)  Explain to the children that you have the TENS and they have the ONES.  Continue counting this way for the following exercises: 20 and 8, 60 and 7, 80 and 5, 90 and 9. Every time you begin a new exercise (20 and 8) ask them: “How many tens (groups of ten counters) do I need to have?” (2), “How many ones do you need to have?” (8)

23 36 9 8 + 45 + 21 - 5 - 1

Drawing a Circle and Colouring it’s Interior 10 min  Tell the children to have a blank page and their pencils ready. Ask them to draw a shape called a CIRCLE. Observe how they are drawing (sketch, use of coins, use of round counters, etc.) Allow them to draw how they think a circle should be.  Discuss how these drawings can be improved so that they look more like what a CIRCLE looks like. Teacher, if the children did not use round objects (coins, corns, base of a cup, round eraser, etc.) to draw, you can suggest this to them. Tell them not to erase what they already drew, but that they can improve their drawings with the help of a round object.  Ask them: “Which of your drawings is closest to a circle?” Tell them to write the name CIRCLE below that drawing and mark the boundary of the shape (the one they think is closest to a circle) and colour its interior. Copying Exercises for Homework (addition and subtraction) 5 min  Teacher, copy on the board the exercises from the box. Tell the children to copy these exercises into their books and finish them for HOMEWORK. Lesson 14

Checking Homework  Tell the children to exchange their homework with another student to check the exercises. Ask the children to review the exercise and mark them (right, wrong) and give them back to their owners.  Then, ask four children to solve the exercises on the chalkboard. Allow them to use drawings of counters, fingers or other objects to find the answer to each exercise.  Ask the other children to check the exercises again to see if their partner checked their homework correctly.

Emphasize the word HUNDRED. 100: One Hundred 200: Two Hundred

A A B A A B A A B ..

5 min Writing Numbers and Reading  Tell the children that you are going to say a number and they will write in their exercise books.  Ask the children to write the following numbers: 100 200 300 400 500 600 700 800 900  Ask the children to say how each number is written. Ask one child to say how “100” is written (one, zero, zero or one, double zero). Then ask another child for “200”, and so on until 900.  Have the children read the numbers aloud, and pay attention to the way they say them (see box) Reading Patterns and Saying What Comes Next 10 min  Teacher, copy on the chalkboard the pattern shown in the box. Remember that all the children need to be able to see it clearly. (Make each drawing large enough for each student to see).  Ask the children: “What kinds of lines do you see on the chalkboard”? (closed line, closed line, open line, etc.) “In this pattern, what do you think would come next?"

5 min Recall the Audio Programme  Tell the children that you are going to review ‘The Children’s Song”  Read the lyrics to the song to them, aloud, so that they are clear on all the words.  Ask them to sing the song with you. 10 min

Interior

Boundary

Interior, Exterior and Boundary (contour) of a Shape  Ask the children to draw a circle and colour the boundary (contour) with one colour, the interior with another color and the exterior with their pencil.  Have them write the words ‘boundary’ (or ‘contour’), ‘interior’, and ‘exterior’ in the appropriate locations on their drawing.

Patterns 15 min  Teacher, organize the children in pairs. Tell them that they are going to shake each others hands according to the instructions you give them.  Ask each pair to follow your instructions: Say “Pair of children, shake with your right hands, shake with your left hands, shake the left hand with right hand.”  Ask each pair to repeat this pattern: shake with your right hands, shake with your left hands, shake left hand with right hand. Observe that each pair is making the right pattern.  Then, incorporate a change in the pattern. Ask the pairs of children to repeat the pattern, but every time they move their hands they need to say “right hand” or “left hand” respectively. Discuss with them the difference of these two patterns (the last pattern incorporates sound).

Check the worksheets to see the children’s progress and give special attention to those who need it. Review 4

PART 2: The After-Audio Programme TEACHER: Facilitate the following activities 10 min

Saying the Aproximate Number of Children in Our Class - Estimation  Tell the children: “Look at the children around the class and think about how many children there are all together. Write that number in your exercise book.” Teacher, as a strategy to improve the children’s ability to approximate the number of children, ask them: “Are there more than 10 children?”, “Are there more than 15 children?” “Can you say that there are less than a 50 children?”  After this discussion ask the children to think about the number of children that there are in the class, and to write this number in their exercise books again.  Teacher, ask the children: “How can we know how close you are?”, It’s possible that the children will suggest counting one by one. After the class does this, allow the children to form groups of tens and count by tens and ones. Write the number on the blackboard. The children should see that both ways of counting give the same number of children. As a class, discuss which way they think is easier.  At the end ask them: “Which of you were close?” “How close?” (verify the students answers)

5 min Colouring the Interior, Exterior and Boundary (contour) of a Triangle  Teacher, draw a triangle on the chalkboard (see box) and ask the children to copy it in their exercise books.  Using their crayons, tell the children to colour the INTERIOR (inside) of the triangle with one colour, the EXTERIOR (outside) with another colour, and trace the CONTOUR with a third colour. Write these names (interior, contour and exterior) on the appropriate parts of the triangle. 5 min

Answering to Combined Addition and Subtraction Exercises – Homework  Teacher, on the chalkboard, copy the exercises that are in the box. Ask the children to copy them into their exercise books.  As a class, find the answer to the first exercise: (3 + 2 – 1 =). Use counters, fingers or drawing circles as strategies to find the answer. Encourage the children to use their own way of finding the answer to each exercise. Tell the children to complete the remaining exercises for homework.

For the next lesson, you will need 12 sticks, each the same length, for each group of children. Lesson 17

Reviewing Homework 5 min  Tell the children that they are going to work in PAIRS to correct their homework. Tell them to switch their exercise books with their partner and mark each exercise using the usual marks for “right” and “wrong”. Give them a few minutes to do this and ask them to give back the exercises books to their owners.  Ask one of the children to READ the first exercise, including the answer. Ask the class: “Is three plus two minus one equal to four?” Allow the children to verify their answers using fingers or by drawing circles. Then, tell each child to look at the exercises that their partner marked and correct it if needed.  Continue marking the remaining exercises in the same way. Comparing Lengths – Longer Than, Shorter Than, Same Length. 5 min  Teacher, invite each pair of children to look around the class and choose the following objects according to the instructions: - Two objects of different length and say which one is “shorter” or “longer”. - Two objects of the same length.  Ask them to describe the lengths of each pair of objects. Encourage them to use sentences such as: “… is shorter than …”, “...is longer than...”. or “… has the same length ” Ask them to show you the length of each pair of objects and the difference in length between them.

10 min Explaining the Characteristics of a Triangle, a Square and a Rectangle  Teacher, you will need 12 sticks of the same length for each group of children.  Organize the class in groups and give each group twelve sticks. Explain to them that they will make shapes using these sticks, and that they need to use all of the sticks every time they make a shape.  Using the 12 sticks, ask them to make triangles and see how many triangles they can make. (4 triangles). Encourage them to discuss and identify the characteristics of the triangles they made. Ask them: “Can you use more than one stick as a side of a triangle?” (yes) “Can you make one triangle with the 12 sticks?” (yes). Ask them to show you this (four sticks per side)  After a while, allow the children to make squares with the 12 sticks and count the number of squares they made (three). Ask them: “Can you make one square with the 12 sticks?” (yes). Encourage the children to show this.  With the same 12 sticks, ask “How many rectangles can be made?” (two). The children need to remember the characteristics of a rectangle and make rectangles using the sticks. Lesson 18 IRI Mathematics Grade Two

Describing a Pattern of Shapes  Teacher, draw the two rows of shapes on the chalkboard. (see the box)  Talk with the children about the shapes on the top row. Tell them, “the first shape is a circle.” Ask “What is the second shape?” (triangle), “What shape is the third?” (circle), “What shape is next?” (triangle), etc. Encourage the children to keep saying the names of the shapes that come next. Next… Ask them: “How many more can I draw?”  Teacher: Explain to the children that this is a PATTERN: Circle, triangle, triangle, circle, …  Tell the children to look at the next pattern (on the second row) and read it loud: Circle, _________________ triangle, triangle, circle, triangle, triangle…  Ask the children: “What shape comes next?” (circle), “How do you know it’s a circle?”  Tell them to look at the same shapes and ask: “Do you see another pattern in the same row?” (coloured, not coloured, not coloured, coloured, not coloured, not coloured, …) Ask “What do you think could come next?” (coloured). Ask the children to copy this pattern in their exercise books and write the title ’PATTERN’. Comparing Lengths: Longer Than, Shorter Than, Longest, Shortest 5 min  Teacher, draw a “pipe” in the horizontal position, on the chalkboard. Ask the children to copy this drawing in their exercise book. (The pipe can be of any length).  Next, ask them to use their pencil and ruler to draw a line underneath this pipe that is longer than the pipe. Then, underneath of this, draw a shorter line. Underneath of this, draw a shorter line. Underneath of this, draw a longer line.  Go around the class to help the children and to make sure that they are drawing the lines according to the instructions. The children can also use a string/rope to measure.  Encourage the children to look at all the lines they drew. Then, choose the longest line and colour it. Explain that longest means the one that is longer than all the others, and shortest means the one that is shorter than all the others. Ask the children to mark the shortest line. *For the next lesson, you will need cardboard triangles of different sizes and different lengths of sides.

Recognizing Hundreds, Tens and Ones  Teacher, tell a story to children: “Mr. Joe sells exercise books to schools. He sends exercise books in boxes. The big boxes have 100 exercise books each and each small box has 10 exercise books. He also sends by exercise books by ones”. Tell the children to order exercise books in groups. Allow one group of children to only order boxes of hundred exercise books, another group can only order the ten boxes and a third group the ones. Teacher, ask a child from the group ordering hundreds, the following: “How many boxes of hundreds would you like to receive?” (e.g.: 4) “How many exercise books do you expect to receive”? (e.g.:400) Then, ask a child from the group ordering tens, the following: “How many boxes of tens would you like to buy”? (e.g.: 2) “How many exercise books do you expect to receive?” (e.g.:20) Then, ask a child from the group ordering ones, the following: “How many exercise books would you like to buy?” (e.g.: 5) “How many exercise books do you expect to receive”? (e.g.:5)  Teacher, on the Chalkboard, write the order of exercise books (write the numbers on the dotted line) and draw the relative numbers of boxes and ones. (see box)  Ask the class: “How many exercise books are you going to receive?” Tell them to write that number on their exercise books.  Continue this way, allowing the children to place two or more orders. Tell the groups that they are also allowed to say that they don’t want to place a particular order. (this can be interpreted as ZERO) Describing a Rectangle and a Square - Vocabulary 10 min  Teacher, show a RECTANGLE made of cardboard or a drawing of it on the chalkboard to the class. Ask for the name of the shape (rectangle).  Ask one child to come in front of the class and point to the four sides (straight lines). Talk about how two sides are longer than the other sides. Allow the children to verify.  Ask the children to identify the following: the interior (inside); exterior (outside); four corners/points;and the boundary/contour (a closed line containing the four sides)  Teacher, do the same for a SQUARE (four sides of the same length) Tell the children to draw a rectangle and a square in their exercise books, write their name of each shape, and colour the interior, exterior and boundary of each shape. *For the next lesson, you will need a string/rope.

This rectangle can be drawn using 3 little squares for one side and 2 little squares for the other side. (see box)  Ask them to look at the interior of their rectangle and count the number of little squares that are in there.  Ask the children: “How many little squares are there?” (6 little squares). Tell them to  colour the little squares.  Ask them to draw another rectangle. This rectangle can be: Two little squares by four little squares, or two little squares by one little square. NOTE: Teacher, the non-standard unit to measure the area of a rectangle, in this case is “a little square”. Measuring Lengths and Comparing Lengths – “Longer”, “Shorter”

10 min

 Teacher, draw a small rabbit and an outline of the same rabbit, but without its tail and whiskers on the chalkboard or a piece of paper (poster). The children need to measure the rabbit’s tail and the whiskers.  Tell the children to copy the outline of the second rabbit and finish this drawing by following these instructions: - Give the second rabbit a shorter tail than the first. - Give the second rabbit longer whiskers than the first. TEACHER: Encourage the children to use the piece of string/rope to measure the length of the tail or the whiskers.  Teacher, the children can also complete the outline by drawing a tail and whiskers of he same lengths. Allow them to colour their drawing. *For the next lesson, you will need different sizes of cardboard squares, rectangles, triangles and circles, and a bag. Lesson 22

Ensure that the children are writing the numbers in the correct columns (ones, tens).  Ask one child to read the whole first exercise, including the answer (thirty minus twenty is ten) and allow the other children say if the answer is correct or not. Make corrections if necessary. Check the other exercise in the same way.

10 min

Name the Shapes knowing their Characteristics  Teacher, you will need shapes made of cardboard: a square, a rectangle, a triangle and a circle. These shapes need to be in a cloth bag.  Tell the children to pay attention to the description of the shapes that you give as you draw them.  Draw a large square and describe it as you draw it. I am drawing a shape with four straight sides. Look, it has four corners. Each side is the same length.  Repeat the process as you draw a large rectangle, a large triangle and large circle. As you draw each shape encourage the children to copy you, using their finger to draw the shape on the table, or in the air.  Once you have drawn all four shapes, show the children the cloth bag full of shapes.  Choose a child to take out a shape. Before they show it to the class, help them describe it while using their fingers to identify each line or corner. It has straight sides. It has corners. Encourage the rest of the class to guess the shape. Ask “Is it a square?”, “Is it a rectangle?” Tell them to point to the matching shape on the chalkboard  Repeat this exercise with different children.  Ask the children to draw a square, a rectangle, a triangle and circle as homework. *For the next lesson, you will need a rectangular piece of paper and a square sheet of paper for each pair of children in the class.

 Tell the children to turn to a “blank space” in their exercise books and write a title that says: Number of little squares in a rectangle. You can write this title on the chalkboard too.Tell the children to draw a rectangle using the little squares in their checker line exercise books. This rectangle should be 4 rows of 2 little squares. (see box).  Ask them to look at the interior of their rectangle and count the number of little squares.  Ask the children: “How many little squares are there”? (8 little squares). Tell them to colour in those little squares.  Tell the children to turn to another ‘blank space’ in their exercise books. The next rectangles that they can draw are: Two rows of four little squares, three rows of three little squares (notice that this second shape is a square that has little squares in its interior). NOTE: Teacher, the non standard unit used to measure the area of a rectangle, in this case, is “a little square”. Comparing Lengths of the Sides of a Rectangle and a Square

5 min

 Teacher, this activity can be done in pairs. Each pair of children needs to have a sheet of paper that is in the shape of a rectangle, and another one that is in the shape of a square.  Ask the children to look at both shapes and say what is the difference between the two shapes (Rectangle: Not all sides are equal in length – 2 sides are short and two sides are long. Square: 4 straight sides that are all the same length)  Ask them: “How can you show me what you just said about the rectangle?”, “…and about the square?” (Folding the paper to compare the sides, using a cord/ruler to measure the sides, etc.) Allow the children to find diferent strategies to show this. *For the next lesson, you will need a Hundred Square (one large one or small ones for each child.

Tens and Ones Digits - Hundred Square  Teacher, you will need the Hundred Square for this activity. If you have more than one Hundred Square, make as many groups of children as there are squares. If you only have one, work with the class as a whole.  Organize the children in groups or pairs according to the number of Hundred Squares that you have available (in case that you have a hundred square for the class, work with the whole class).  Ask one group of children to read the numbers in the Hundred Square, from 1 to 20 (1, 2, 3, … 10… 19, 20). Make them notice that those numbers are in ROWS. Ask another group to read the column of tens (10, 20, 30, … 100), and a third group to read the second column (2, 12, 22, 32, …. 92)  Have each group of children point to each number in the thirth column as they observe the ones digit and the tens digit of each number. Ask them: - “Do the ones digits of those numbers (2, 12, 22, 32, ..92) change?” (No) - “Do the tens digits of those numbers change?” (yes)  Teacher, copy the second column on the chalkboard and, with the children, identify the ones and tens digits of each number (observe changes in the tens digit: 2, 12, 22, 32, 42, etc. (0 tens, in the case of the number 2 which is also 02); 2 tens; 3 tens, etc)  Next, have the children observe the second row and find that this time the tens digit of each number in that column does not change, but the ones digit changes (11, 12, 13, 14, 15, 16, 17, 18, 19, 20 ).  Ask a group of children to show (represent) some of the numbers of the second column using counters or drawings of balls. Ask them to represent numbers such as: 2, 12, 22, 32, 42. Recall the Song  Tell the children that, as a group, you are going to review ”The Canoe Song”  Read the lyrics of the song to them so that they are clear on all the words.  Ask them to sing the song with you.

Solving Subtraction Exercises 10 min  Teacher, copy the exercises from the box on the chalkboard and ask the children to copy them in their exercise books. Tell them to find the answers to each of them.  Solve the first exercise with the children. Encourage them to use drawings of little balls for the ones and boxes for the tens to find the answer. Ask them: “Do we begin with the ones or tens?” (ones) 68 “eight minus three”: OOOOOOOO .Then, the tens: “six minus four” / / / / / / - 43 25  For the remaining exercises, the children can continue using this strategy or another strategy that they are more comfortable with (fingers, counters).

10 min

Comparing Lengths of Cords and Using the Respective Vocabulary  Teacher, you will need 4 strings/ropes of different sizes for each group of children.  Organize the children in groups and give each group FOUR STRINGS of different lengths.  Ask the children to discuss how one string is the longest and one is the shortest out of this group of four strings. Compare the lengths.  Teacher, ask some of the groups to explain how they organized the strings. As they describe the strings, encourage them to say “this string is the longest of the four”, “this is the shortest of the four”. Ask the other children if they agree.  Ask the children to draw the four strings in order, from the shortest to the longest. Allow them to apply different strategies to draw (use the same strings as ruler, measure them with a rule, estimate the length, use other object to measure, etc.)

Once they have finished, ask one child to read the whole first exercise, including the answer and allow the other children to say whether the answer is correct. Allow them to make corrections to their work if necessary. Check the other exercises in the same way. Using Non-standard Units to Measure Length 10 min  Teacher, organize the children in pairs. Each pair will work together to find the length of their exercise books.  Ask them what they think they could use to measure the length of their exercise books. If they only suggest using a ruler, ask them what they could use if there were no rulers in the room.  Encourage the children to think of their pencils, erasers, sticks, a piece of string, matchsticks... as units to measure.  Ask each pair of children to measure their exercise books. Allow each pair to use different units to measure - some using pencils others string, erasers, etc.  Ask each pair to tell the others how long their exercise book was. Encourage them to say, “8 matchsticks long” or “5 erasers long” or “4 pencils long”, etc.  Discuss anything that they notice, i.e. that the number of erasers differs in different groups, etc. TEACHER: LET THIS DISCUSSION BE LED BY THE CHILDREN Finding the Area of Rectangles - Multiplication 10 min  Teacher, the children need to use their checker line book. Remind them to use the little squares as a guide so that they can draw fast.  Tell the children to draw a 3 by 2 rectangle (3 rows of 2 little squares). After a few minutes ask them: “What is the AREA of that rectangle?” (6, six little squares) “How much is 3 TIMES 2?” (6). Then, tell the children to colour the area of the rectangle.  Continue the same way with the following exercises: 2 by 4, 2 by 3 and 2 by 2 (this last one is a square shape).  Ensure that all the children are doing this correctly.

15 min

Measuring the Length with a Tool and a Standard Unit – Centimetre (cm)  You will need: Rules (the scale has to be clear and in cm) for each group of children. You will also need 1 sheet of paper, all the same size, for each group.  Teacher, show the children all the sheets of paper. Explain to them that these sheets have the same length and width. Do the same with the rulers, pointing out that all have the same length and, scale that shows 1cm, 2cm, 3cm, etc.  Give each group 1 ruler and 1 sheet of paper. Ask them to look at the ruler and mark the length 1 centimetre and draw a “line” that measures 1 cm in their exercise books. Then write below it, “1 cm”. (see the box)  Teacher, use the ruler and draw a line that measures 1 cm on the chalkboard and write “1 cm.” Allow the children to read “one centimetre” (1cm).  Ask them to show you “2 cm” on their ruler, 3cm, 4cm, 5cm, … 10cm.  Invite each group of children to measure the length of the sheet of paper using the ruler. Encourage them to measure carefully and write the length of the sheet of paper in their exercise books.  Once each group has finished, draw the sheet of paper on the chalkboard. (same size) Then, ask each group: “What is the length of the sheet of paper”? Write the answers, as they say them, on the chalkboard. (see the box)  Discuss the findings with the children. If all the sheets of paper are the same size, you should expect the same measures of the length.

Finding the Answer to Oral Subtractions  Teacher, the exercises shown in the box can be done orally. Allow the children to use different strategies to find the answer. They may use fingers, drawings, counters or other ways that they are comfortable with.  Begin telling them: “Think about fourteen minus eight”. Give them some time to find the answer, as this is the moment when children use different ways to find the answer (some will still add: having 8 in mind they will say 9, 10, 11, 12, 13, 14, then have as answer, 6. Others can decompose 14 into 10 + 4 and take away 8 from 10 and have 2 left, then add 4 and 2 and say 6, etc. After a while, ask the children: “How much is fourteen minus eight?”  Continue with the remaining exercises.

Show them a ruler and ask: - “What is this for?” - “What things can we measure with this ruler?” (write them on the chalkboard) Discuss these answers with the children, highlighting the scale used in the ruler (1cm, 2cm, 3cm, 4cm, … 10cm (decimetre), 11cm,… ).  Ask the group of children to choose two things to measure with a ruler. They can get those two things from around the classroom.  Help the children to ensure that they measure the lengths of the objects, use the ruler correctly, read the scale correctly (position the zero at the beginning of the length of the object to be measured) and write the number of centimetres in their exercise books.  Then allow each group to share with the class the length of the objects they measured. The children should show the length of the object they measured and say: “This length measures …….. centimetres” Comparing Groups of Counters 10 min  Teacher, each child should have 25 counters.  Ask the children to make a group of 12 counters, then make another group/row of 10 counters. Each group/row of counters needs to have some space between them.  Have the children observe both groups (or rows) of counters and answer the following questions: - “Are there MORE counters in the group of 12 or the group of 10?” (12) - “Is twelve or ten the GREATER number?” (12 is greater than 10)  Ask the children to draw the group/row of counters and write 12 and 10 below the respective group of counters. Then, circle the greater number.  Continue the same way with the following pairs of numbers: 9 versus 10 8 versus 5 11versus 14 Review 7

Answering to Oral Addition Exercises  Teacher, tell the children that you will say some oral addition exercises (shown in the box on the left) for them to answer. Tell the children to raise their hand when they are ready to answer.  Begin by asking: “How much is eighty plus ten?” Once the children have had some time to think of the answer, choose a child that has his/her hand raised to say the answer. Allow the class to say whether the answer is correct. If needed, explain the exercise to the children to ensure they understand what they are adding.  Continue the same way with the remaining exercises. 15 min

Measuring Length wih a Standard Unit – Centimetre (cm) & a Non-standard unit.  Teacher, organize the children in groups – each group will measure the lengths of their exercise books. Select some groups (2 or more groups) to measure the length of their exercise books using counters (corks) as the unit of measure (non-standard unit), while other groups use a ruler with a centimetre as the unit of measure (standard unit).  Ensure that each group has the same kind of exercise books, one per group. Show the children the side of the exercise book that they will measure. Encourage the groups to measure and write the length (the number of corks or centimetres) in their exercise books.  Once all the groups have had a chance to write their measurement, write each group’s findings on the chalkboard in the following way: Findings of the groups Corks as unit Centimetre as unit ………….. corks ………… centimetres ..………… corks ……….. centimetres ..………… corks ……….. centimetres  Teacher, lead a discussion with the children about these findings. Point out to them that although each group measured the same length (show the length of the exercise book) there are different measurements. Discuss the findings of the groups that used corks and see if they are the same or not, and how close they are to each other. Do the same for the groups that used centimetres.  Ask the children: “Which way to measure the length of the exercise books do you prefer? Why?” *For the next lesson, you will need a ruler and pieces of string/rope. Lesson 29

Solving Horizontal Subtraction Exercises - Written Answers  Tell the children to complete the subtraction exercises (shown in the box on the left) according to the instructions given during the audio programme.  To help the children find the answers faster, an ilustration that show that only the ones can be touched or striked through may be helpful. For example : 57 – 4 = 53 OOOOOOO  Tell the children to write the answer to each exercise. As a group, check the answers to each exercise while the children correct their work.

10 min Measuring Length  Teacher, you will need: A ruler and a string/rope that is the length of your right foot.  Show the children the string/rope and tell them that it is the length of your right foot. You can also show them the ruler and its division in centimetres.  Discuss with them the various ways to measure the length of your foot (measure the string/rope, mark your foot on a piece of paper and measure it, measure it when you are standing, etc.). Tell the children to choose one way of measuring it and allow two of the children to find the length of your foot. Then, have all the children write in their exercise books the following: “the length of my teacher’s foot is…”  Ask the children to measure the length of their own right foot and write it in their exercise books.

3 min Homework  Teacher, for the next class, tell each child to bring a string/rope that shows his/her height. In their exercise books, each child should also make a drawing of himself/herself, with their height written in centimetres. Encourage them to ask for help at home. Lesson 30

Finding the Answer to Addition Exercises  Continue solving the exercises with the kitten. Reviewing Homework from Lesson 30  Review and mark the homework from the previous lesson. 5 min  Encourage the children to share how they measured their height and the kind of tool they used or who helped them.  Teacher, you may want to display the strings or cords that each pupil has brought to measure their height. Write the number of centimetres of each child’s height on cardboard. 10 min Naming a Shape and Create a Repeating Pattern.  Teacher, draw a square with divisions, as shown in the illustration on the left. The square is divided into four equal parts.  Tell the children to draw a similar square in their exercise books. Then, ask: “How many squares does the shape have?” (5). Ensure that each child counts the squares inside and the initial (larger) square before it was divided. Once the children identify the squares, tell them to colour in the squares, each with a different colour.  Draw a rectangle with divisions, as show in the illustration on the left. The rectangle is divided into three parts. Tell the children to draw a similar shape in their exercise books.  Ask them: “How many rectangles does the shape have?” (4). Tell them to colour in the rectangles, each of them with a different colour. 5 min Adding Numbers Which Sum is 10 – Number Bond to 10  Teacher, tell the children that you will play a game in which they will need to find a number with your help. You, teacher will give them some “clues”.  Begin, telling the children: “Listen, listen carefully. The number you need to find likes to be with another number and the sum of both of them is always TEN. This is why the number you are looking for is a friend of the number ten.” Ask “Which numbers are friends of 10?”, “Are 1 and 9 friends of 10?” (yes, because 1 + 9 = 10). Write “1” and “9” on the chalkboard. “Are there more friends of 10?” (yes) “Which ones?” (2 and 8, 3 and 7, 4 and 6, 5 and 5). Ask the children to write all of them in their exercise books while you write them on the chalkboard.  Tell the children: “So far you know that the number you are looking for is a friend of the number 10. You already found all the friends of ten. Do you need more help to find the number?” For the next clue, tell the children: Listen carefully: The number you are looking for is one of the friends of the number ten to which you add 4 and gives you 7. What is the number? (3) Lesson 31

The remaining exercises should be completed as HOMEWORK.  Tell the children to READ the first exercise, together, and aloud: “Two times three”. Ask: “How much is two times three?” (6). If the children have difficulty giving the correct answer, help them by drawing, on the chalkboard, the following: “a two by three rectangle” or “a group of two by three little balls.” OOO OOO Then, ask the children, how many little balls are there? (6). “So, how much is two times three?”  Complete the second exercise with the children. Ask them to complete the remaining for homework. Colouring the Area of Rectangles  Teacher, tell the children that we will now draw rectangles and squares in their checker exercise books. Tell them to begin by drawing a 2 by 3 rectangle. Once they have drawn this, ask questions such as: a. “What kind of shape did you draw?” (rectangle) 10 min b. “Is that rectangle 2 by 3? or 3 by 2?” (2 by 3) c. “How many little squares are there in that rectangle?” (6) d. “Are the little squares in the interior or exterior of the shape?” (interior) e. “What is the AREA of that rectangle?” (6)  Have the children colour each little square. They can use different colors for the little squares. Then count the little squares to verify that the area is 6.  Continue with the following rectangles: 4 by 2; 3 by 3 (square). The main question that the children should understand is “What is area?” and be able to colour the area of each rectangle or square. Lesson 34

Making Patterns with Our Body – “Guess” the Next Move 5 min  Teacher, stand in front of the class and ask the children to observe as you do the following moves in the order given: roll, twist, stretch, roll, twist, stretch.  Ask the children to follow a sequence of moves - roll, twist, stretch, roll, twist, stretch. Stop the children suddenly and ask which movement would come next (roll). Then, allow them to continue this pattern for a while.  To end this activity, ask one child to come in front of the class and make a new pattern with his/her body. Ask the rest of the class to follow this pattern.

10 min Measuring Parts of Our Body: Hand-span  Teacher, the children will need their rulers, at least one for each desk or table.  Show the children your hand span. Ask one of the children to help you to measure the length of it with a ruler. Then draw your hand span on the chalkboard and show the length of your hand span and write the number of centimetres that it measures.  Ask the children to do the same. Instead of drawing their hand spans on the chalkboard they can use a blank page in their exercise books. Tell them to write the number of centimetres under their drawing. Walk around the classroom as the children work to ensure that they are using the ruler well.  When they have finished, allow each child to share their findings with the class. *For the next lesson, you will need 10 pieces of cord, each cut to 10 cm in length, and ten pieces of cord, each cut to 1 cm in length.

Each part has a length of 10 centimetres and is called a DECIMETRE (see box). You will also need pieces of cord or paper that are 1 centimetre in length each.  Organize the children in GROUPS. Each group will measure the length of the cover of their exercise books (the longest side). Give each group a cord or piece of paper that measure 10 centimetres and a piece that measures 1 centimetre of length.  Tell the groups of children to discuss how they can use the two cords (or pieces of paper) to measure the cover of their exercise books.  Allow the children to discuss in their groups. After a while, ask “How many centimetres does that side have?”, “How did you measure it?”, “How many decimetres and centimetres is the length?”  Draw the cover of the exercise book on the chalkboard and measure the same side that the children measured using A DECIMETRE (10 centimetres) and 1 CENTIMETRE. Talk about how each is used to find the length of the longest side of the exercise book cover. Write the number of centimetres on the chalkboard (near the side being measured) or the decimetres and centimetres  Tell the children to copy this drawing (and the number of centimetres or decimetres and centimetres) in their exercise books.

Review activities TEACHER: Facilitate the following activities 10 min

2x3=6 4x2 3x3 2x2 1x2 3x2

Solving Multiplication Exercises with Rectangles  Tell the children to have their exercise books and pencils ready – we will use rectangles to solve multiplication exercises. Remind them to use the little squares on the pages of their exercise books to help them draw the rectangles easily. Begin with the first exercise (see box): 2 x 3. Ask the children to draw A TWO BY  THREE rectangle (see box). Then, ask the children: -“What is the area of that rectangle?” (suggest that they can count the little squares to find the answer) -“How much is “two times three”?” (six)  Ask the children to write: 2 x 3 = 6 below the rectangle they just drew.  Teacher, write the other exercises (see box) on the chalkboard and ask the children to solve those exercises in the same way. Help the children as needed.

10 min Writing Multiplication Exercises  Teacher, draw the rectangles (with the little squares in each) shown in the box on the chalkboard.  Tell the children to look at the first rectangle. Ask them: - “Is that rectangle a 3 by 2 rectangle or a 2 by 3 rectangle?” (3 by 2 rectangle) - “Why do you think that it is a 3 by 2 rectangle?” (allow the children show you the three rows and the little squares (2) in each row). “How much is three times two?” (6)  Write 3 x 2 below or close to the first rectangle (3 by 2 rectangle)  Ask the children to copy the remaining rectangles in their exercise books and write the multiplication exercise that goes with each of them. Encourage them to find the answer using the strategy you just used to solve the first exercise.

*For the next lesson, you will need 2 boxes. Review 9

10 min

Making 10 (Number Bond to 10)  Tell the children you are going to call out a number below 10 and they are to call back the number that, with your number, will make 10.  Give an example; “If I say 1 – you must think what needs to be added to 1 to make 10.” Let the children tell you 9. Once they understand you call out 1 they call back 9.  Begin by calling the numbers in order forwards: 1, 2, 3, 4, 5, 6, 7, 8, 9. Then, call the numbers backwards: 9, 8, 7, 6, 5, 4, 3, 2, 1 and zero. If the children are able to answer the exercises correctly, continue by calling out the numbers in random order.

10 min Vocabulary for Circle  Have a range of circles (cut out of card, lids from containers…) to show to the children; give at least two circle to every table of children.  Ask them to look and play with the circles and think of words that describe them.  Record the words the children say on the chalkboard. Help them to think of terms such as curve, round, can roll, flat, circular, close line to describe the circles.  Tell the children to write in their exercise books the following title: ‘THE CIRCLE’. Below this title, tell them to draw a circle using a circular object or the cut outs that they have (cutouts from cards or the lids from containers).  TEACHER: MAKE A DISPLAY OF THE CIRCLES AND THE DESCRIBING WORDS IN THE CLASSROOM – you may even want to take some time during an art lesson to paint circles for the display.

.. cm ….. m …...cm

15 min Measuring Length Using a Metre  Teacher, you will need a metre stick.  Tell the children a story such as: “The head teacher of the school would like to replace the chalkboard for a new one of the same size. How can we find out the size of our chalkboard?” Chat with the children about this.  Show the children a metre stick. Ask them if they know what it is called. Tell them it is a metre and it is used to measure LENGTH. Ask: “Who would use a metre stick in their work?” (Seamstresses for measuring materials, carpenters, etc). “Can we use this to measure the size of the chalkboard?”  Hold up the metre stick up for the children to see. Ask them if the length of one side of the chalkboard is more or less than one metre. Hold the stick by the length of the side of the chalkboard so that all the children are sure. Ask the same question about the other side of the chalkboard.  Ask the children: “Who would like to measure the length of each side of the chalkboard?” Allow one or two students to come to the front for this exercise. Show them how to use the metre stick and how to read it. (e.g.:4 m and 20 cm) Encourage them to see if it is necessary to measure all the sides, or if they can know the length of the other sides without measuring each side. (rectangle shape – opposite sides are equal)  On the chalkboard, ask the children to draw a rectangle to represent the chalkboard. Tell them to write the length of each side that they measured by writing the number of metres and centimetres of each side.  Invite another group of children to measure the same sides and write their findings. Continue with other groups of children. Then, compare the results from each group and discuss the differences. (way of handling the metre stick, read it, counting, etc.)

Marking the Date of My Birthday in the Calendar (homework) 5 min  Teacher, tell the children to find out the day they were born and mark this day in a calendar. They also have to answer the following question for homework: “How old are you?” *For the next lesson, you will need 3 sticks of different lengths and a calendar. Lesson 42

Calendar: Days of the Children’s Birthdays  Teacher, you will need a calendar with the twelve months of a year.  Copy the table shown in the box on the chalkboard. Later, you and the children will complete this table.  Ask the children to write the month of their birthday in their exercise books.  On the calendar, ask each child to come up and mark the date and the day of their birthday. Then, tell each child to write the day of their birthday in their exercise books. Encourage them to write: My birthday is on …............(Sunday, Monday,…. Saturday)  Then, complete the table on the chalkboard, asking the children to raise their hands if their birthday is on Sunday. Ask one the children to count how many children have a birthday on Sunday, and write that number on the table. Do the same for the rest of the days of the week. At the end, read the table with the children: “On Sunday there are ……… birthdays”, “On Monday there are …. birthdays”,” On Saturday there are ……. birthdays”, and so on.  Ask the children: “How long does your birthday last?”, “Does your birthday last two days?” “Which day would you like the most for your birthday?” Point to that day in your calendar. Ask “Why do you like that day?”  Ask the children to copy the table in their exercise books.

10 min

Describing Symmetry  Teacher, you will need leaves of a plant that show symmetry and an exercise book to show the middle blank pages. You will also need to show examples of symmetry such us: a face of a child or yourself (right and left side of the face) and the whole body (right and left).  Teacher, cover the left side of your face. Have the children observe and tell you what they see on the right side (one eye, an eyebrow, half of the nose, etc.). Then uncover the other side and ask the children: “Do you see the same things on this side of my face?”, “Are they at the same distance from the middle line?”  Explain to the children the meaning of SYMMETRY (same things on both sides and they are at the same distance from the middle line).  Teacher, ask the children to make similar observations of symmetry for the leaves of the plants, their body or the middle blank pages of their exercise books.

Number Bonds to 10 – Different Combinations to Make 10 10 min  Teacher, the children will use their fingers to find answers to oral exercises. Explain that with three hands, they will show TEN (10) fingers. Ask a child to the front and show two fingers on one hand.  Then, tell the class “Get ready to show the fingers that, with the two fingers that the child at the front is showing, will make 10.” Tell them to use both hands. Encourage them to make different combinations (5 and 3, 4 and 4). Remind them to use their own two hands and take into account that there is a child showing two fingers.  Identify another child to come to the front of the class and ask him/her to show five fingers. Then, tell the class: “Show me fingers on two hands that, when added to the five fingers, makes 10.”  Continue inviting other children to show: 1 finger (others show 9); 0 fingers (others show 10 fingers; 9 fingers. (others show 0 fingers and 1 finger) 15 min Vertical Addition and Horizontal Subtraction  Teacher, copy the exercises shown in the box on the chalkboard and ask the children to copy them into their exercise books.  Solve the first addition exercise together. You can illustrate this addition on the chalkboard: 14 + 38

44 – 40 = 85 – 80 = 97 – 90 = 41 – 40 =

oooo oooooooo

Then, add the ones (oooo oooooooo) and show that the sum is oo = 12. Show them that the 2 is written below the eight (in the ones column) and the 1 is written above the one (in the tens column). Then ask the children to add the numbers in the tens column: and and OR 1 + 1 + 3 = 5 ( ). Show them the 5 is written below the 3.  Summarize with them that the whole exercise can be seen like this: 14 + 38

oooo oooooooo

52 oooooooooooo This is the same as oo  Invite the children to solve the remaining exercises by themselves, including the subtraction exercises. Allow them to use their own strategies to find the answers. *For the next lesson, you will need one calendar, and metre sticks for each group of children. Review 11

To start, have the children write the title of this project in their notebooks: Project: Making my own METRE. Then, ask: - “What are you going to need to construct a metre (tool)?” Write the list of materials suggested by the children on the chalkboard. Choose some materials that are easy to find at home and have the children write these in their exercise books. - “At home, with whom are you going to talk about this task?” Have each child write the name of the person whom they will ask for help at home. - “When can you construct this metre?” Have the children mark the dates on the calendar or write the dates in their exercise books. NOTE: Plan this project so that the children can have their metre (tool) ready by the day before the closing lesson of this term.  Teacher, give some guidelines to the children for their project Their metre has to show each cm up to 100 cm Each mark for the centimetres has to be clear. They can use a ruler to help themselves in the marking process. Show them how to mark each cm, draw this on the chalkboard using the ruler.  By reviewing these guidelines with the children, you will be able to show them that all the tools (metre) will have the same length (1 metre), the same scale, and that each mark will represent the following: 1cm, 2cm, 3cm, … 100 cm. Although each student’s project will have these characteristics in common, the materials used for each tool can be different.

Singing “The Song for the Months of the Year”  Teacher, invite the children to sing “The song for the months of the year.”  Discuss with the children the celebrations in each of the months mentioned in the song. *For the next lesson, you will need a calendar.

Applying Symmetry when Making a Paper Airplane  Teacher, you will need a sheet of paper for each child. They will make an airplane (see the drawing in the box) by applying what they know about SYMMETRY.  Show the children a model airplane made of paper.  Give each child a sheet of paper and ask them to make an airplane like the one you showed them.  Give them the first instruction or step and point out how each side of the airplane should look. Ask the children to look for symmetry. Then give them the next step and ask them to look for symmetry. Continue giving them one step at a time, and each time reminding them to look for a symmetrical pattern.  You can also invite the children to color parts of their airplane, keeping in mind that they should colour the parts in such a way that it shows symmetry.

Vacation Months: - December - March, April - July, August (not always the entire month)

Planning My Vacation – Calendar  Teacher, on the calendar, show the children the month(s) of the next vacations.  Ask them: - “What month(s) are you going to be on vacation?” - “Are you going to be on vacation during December?” 10 min - “How many days does December have?” - “On which day in December does your vacation begin?” - “Which day is the last day of December?” - What important celebrations are there in December?” (Christmas, some birthdays, and perhaps other days the children consider important)  Tell the children, for HOMEWORK they are to draw the December calendar and mark all the days of vacations and important celebrations in their exercise books. Encourage them to use colours and ask for help at home. Singing a Song “The Days of the Week”; Ordinals  Say the days of the week, in order, to the class. Ask them to say them with you.  Ask questions such as: “What day is today?”, ‘What days do you come to school?”, “What days do you stay at home?”, “On which day will vacation begin?”  Teacher, invite the children to sing the song: “The Days of the Week”

*Teacher, remind the children to bring their METRE-TOOL for tomorrow.

Reviewing Homework: December Calendar – Vacation Time 10 min  Teacher, invite the children to show their December calendar (Homework) and explain that together, we will review. Each child should have a pencil to check their homework.  Lead this review by asking: - “Do your calendars have the name of the month?”, “What is the name?” (December). Write it on the chalkboard or show the name in a calendar. - “What day of the week is the first day of December”? (all need to have the same day if the calendar is of the same year) - “What day of the week is the last day of December”? (all need to have the same day). - “How many days does December have?” (have each child counts – 31 days). - “Did you mark the day for Christmas?”, “What day is it?”, “What date? (25th of December), “What other days did you mark in your December calendar?” - “How many days did you mark for vacation?”, “On what day does vacation begin?”, “What date?”  Teacher, end this activity by asking: “In which month are we coming back to school?”, “What day of that month are we going to begin school again?”

10 min Sharing the Student’s Projects: The Metre (tool)  Teacher, the children can show their metre-tools to the class.  Invite one of the children to show his/her METRE and explain how he/she made.  Ask the class: - “Do all the metre-tools you made have the same length?” (yes - discuss this and allow the children to compare, putting the tools side by side) - “How many centimetres does you metre-tool have?” (100 cm – allow them to verify) - “How is your metre-tool marked?”, “Did you put a mark for each centimetre”?, “… each decimetre?”  End this activity by allowing the children to share their work with each other. NOTE: Teacher, ask the children to have their metre sticks and December calendar ready for the display during the last day of mathematics class. Lesson 51
