MA.3.NSO.1.2 – Compose and decompose four-digit numbers in multiple ways using thousands, hundreds, tens and ones. Demonstrate each composition or decomposition using objects, drawings and expressions or equations.

OBJECTIVE: Students will identify different ways that a four-digit number can be written using decomposition.

MATERIALS: (Per Group of 4)

10 red counters

60 yellow counters

60 blue counters

60 green counters

4 small paper cups

1 Decomposition sheet

1 marker

LESSON DISCUSSION:

• Explain that a four-digit number can be decomposed in more than one way.

• Explain how regrouping works (10 ones equal 1 ten, 10 tens equal 1 hundred, and 10 hundreds equal 1 thousand.)

Procedure:

Step 1: Print one Decomposition sheet for each group of 4 students.

Step 2: Provide each group with 10 red counters, 30 yellow counters, 30 blue counters, 30 green counters, 4 small paper cups, 1 Decomposition sheet, and 1 marker.

Step 3: Instruct the students to arrange the 4 small paper cups in a row.

Step 4: Tell the students to label the first cup “THOUSANDS”, the second “HUNDREDS,” the third “TENS,” and the fourth “ONES.”

Step 5: Explain to the students that these cups will serve as the place value exchange.

Step 6: Ask the students to take out their Decomposition sheets. As a class, do the first one as an example. Use the colored tokens to decompose the first number. Explain to the students that each red counter represents 1 thousand, each yellow counter represents 1 hundred, each blue counter represents 1 ten, and each green counter represents 1 one.

Step 7: The first number on the Decomposition sheet is 1,234. To decompose this number, place one red counter in the THOUSANDS cup, two yellow counters in the HUNDREDS cup, three blue counters in the TENS cup, and four green counters in the ONES cup. Explain to the students that the counters in the cups represent one way to decompose 1,234. Record this decomposition in the second column of their Decomposition sheet.

Step 8: Instruct the students to take one yellow counter from their HUNDREDS cup. Ask them again what this one yellow token represents (1 hundred).

Step 9: Tell the students to exchange the one yellow counter with ten blue counters, as 1 hundred equals 10 tens. Put the ten blue counters into the TENS cup. Ask the students to write another way to decompose 1,234 using the current number of counters in the cups. Have the students record their chosen ways in the third column of their Decomposition sheet.

Step 10: Instruct the students to take two blue counters from the TENS cup. Ask them again what these two blue counters represent (2 tens).

Step 11: Tell the students to exchange these two blue counters with twenty green counters, as 1 ten equals 10 ones and 2 tens equal 20 ones. The students should add twenty green counters in their ONES cups. Ask the students to write another way to decompose 1,234 using the current number of counters in their cups. The students should record their way in the fourth column of their Decomposition sheets.

Step 12: Have the students use the methods taught to them to complete the rest of the numbers on the Decomposition sheet as a group.

Essential Question for Discussion or Journaling:

Explain how decomposing a multi-digit whole number is related to writing the multi-digit whole number in expanded form.

DIRECTIONS: Decompose each number three different ways.

Explain why using 10 tens instead of 1 hundred does not change the value of the number.

Name: LEVELED PRACTICE 2 – MA.3.NSO.1.2

DIRECTIONS: Decompose each number using ones only, then using tens and ones only, and then using hundred and ones only.

Decompose the number 4,752 in three different ways. How would you draw a picture to represent each of these decompositions?

DIRECTIONS: Use decomposition to fill in the missing values.

4,250 = 4 thousands + 2 hundreds + _____ ones = _____ hundreds + 5 tens

8,060 = 8 thousands + _____ ones = _____ hundreds + 6 tens

1,504 = _____ hundreds + 4 ones = 1 thousands + _____ tens + 4 ones

3,780 = 3 thousands + _____ ones = 3 thousands + _____ tens

5,714 = 5 thousands + _____ hundreds + 14 ones = 5 thousands + _____ tens + 4 ones

7,980 = 7 thousands + 9 hundreds + _____ ones = 7 thousands + _____ tens

9,030 = 9 thousands + _____ ones = _____ hundreds + 3 tens

2,400 = _____ thousands + 40 tens = 2 thousands + _____ ones

Explain why using 100 ones instead of 1 hundred does not change the value of the number.

Ma.3.NSO.2.1 – Add and subtract multi-digit whole numbers including using a standard algorithm with procedural fluency.

Objective: Students will learn how to fluently add and subtract whole numbers using knowledge of place value.

Materials: (Per TEACHER)

1 classroom dry erase board

1 dry erase marker

1 dry eraser

Materials: (Per group of 2 students)

1 regular deck of playing cards

1 Write and Wipe holder

1 Adding and Subtracting Worksheet

1 dry erase marker

1 dry eraser

2 numbered bingo chips

2 tens base-ten blocks

Lesson Discussion:

• Review the different terms in place value, such as ones, tens, hundreds, and thousands.

• Teach the students how to perform addition and subtraction using place value. Help the students understand that when adding or subtracting multidigit numbers using place value, always start from the “ones” place value then move left.

• The students will only add and subtract multi-digit whole numbers in this activity.

PART A:

Teacher Preparation:

Step 1: Remove the tens cards and face cards (Jokers, Jacks, Queens, and Kings) from each deck of cards for each group of 2 students.

Step 2: Write the number 10 on 2 bingo chips for each group of 2 students.

Step 3: Place an Adding and Subtracting worksheet into a Write and Wipe holder for each group.

Step 4: Divide the students into groups of 2. Distribute the materials to each group of 2 students.

Procedure:

Step 1: Write the following example on the classroom dry erase board.

Step 2: Explain that the 3 cards in the top row form a three‐digit number, and the 2 cards in the bottom row form a two‐digit number.

Step 3: Ask the students if they know how to find the sum of 537 and 95. Have the students pull the same cards from their deck to follow along with the example. They should put it in the following formation and take out their bingo chips.

Step 4: Explain that to find the sum of multi‐digit numbers, they should add the numbers with the same place value, starting from the ones place and moving left. Tell the students they should treat each place value as an individual addition problem.

Step 5: Have the students find the sum of the numbers in the ones place. Since 7 + 5 = 12 and 12 = 2 + 10, write 2 in the ones place on the dry erase board, and add the 10 to the tens place drawing the bingo chip to represent the 10 being carried over.

Step 6: Have the students go to the next place value and add the numbers in the tens place. While 3 + 9 = 12, we have one 1 tens from the sum of the ones place. So, we have 12 + 1 = 13 for the tens place. Since 13 = 10 + 3, write 3 in the tens place, and add the 10 to the hundreds place, drawing another bingo chip to represent the 10 being carried over.

Step 7: Now have the students to go to the hundreds place value and add the numbers in the hundreds place. Since we only have 5 in the hundreds place, we add the one 1 hundreds from the sum of the tens place to 5. Hence, 5 + 1 = 6.

Step 8: Tell the students that the sum of 537 and 95 is 632.

Step 9: Have the students turn to Part A of their Adding and Subtracting worksheet, return the cards to their deck, and shuffle the cards together.

Step 10: Tell the students that for the 6 problems on Part A of the worksheet, they are to draw 5 cards from their deck, write the numbers that are represented by the cards in the corresponding boxes, and add.

Step 11: Tell the students that whenever the problem calls for them to carry over, they are to indicate it by coloring in the circle next to the number that has the 10 carried over as they indicated with the bingo chip in Step 5 and 6.

PART b:

Step 1: Explain to students that they will be subtracting multi‐digits numbers.

Step 2: Draw the following 5 cards on the dry erase board. Ask the students to pull the same cards from their deck, and place them in the following formation.

Step 3: Explain that when the students start the activity, they will have to draw 1 card at a time. The students cannot have a card with a value of 1 in the tens or hundreds place of the minuend (top number.) They will have to redraw if an Ace is pulled. For the cards pulled to represent the tens and hundreds for the minuend, they must search through their deck to find a card with a value 1 less than the card they drew in an instance where they need to “borrow” when subtracting. For example, if they drew a 2, they will have to find an Ace in their deck to represent 1 and place it behind the 2. In the example below, the card drawn in the tens place was a 5 and the card drawn in the hundreds place is a 2. Therefore, students must find a 4 and place it behind the 5, and an Ace (value of 1) and place it behind the 2.

Step 4: Tell the students to subtract the numbers in the ones place, 3 − 4. Explain that 10 must be borrowed from the tens place in order to subtract. To indicate the borrowing, tell the students to place 1 tens base– ten block next to the 3 to represent 13 − 4, which equals to 9, and remove the 5 card from the tens place to show the 4 in the tens place.

Step 5: Ask the students to subtract the numbers in the tens place, 4 − 9. Explain that 10 must be borrowed from the hundreds place in order to subtract. To show the borrowing, tell the students to place 1 tens base-ten block next to the 4 to represent 14 − 9, which equals to 5, and remove the 2 card from the hundreds place to show the ace in the hundreds place.

Step 6: Ask the students to subtract the numbers. The should get an answer of 159.

Step 7: Have the students turn to Part B of their Adding and Subtracting worksheet. Tell them to replace the cards in their deck, and reshuffle the deck.

Step 8: Tell the students that for the 6 problems on Part B of the worksheet, they will draw 5 cards from their deck, write the numbers that are represented by the cards into the corresponding boxes, and subtract.

Step 9: Tell the students that whenever the problem calls for them to borrow to solve, they should indicate it by coloring in the tens base-ten block next to the number that needs to borrow the 10 like they indicated with the base-ten block in steps 4 and 5.

Extension Activity

Step 1: Have the groups take turns coming up to the board to write and solve addition and subtraction problems up to 1,000 that require carrying over and borrowing. Continue until every group has had a turn and is comfortable with the material.

Ma.3.NSO.2.3 – Multiply a one-digit whole number by a multiple of 10, up to 90, or a multiple of 100, up to 900, with procedural reliability.

Objective: Students will learn how to multiply one‐digit whole numbers by multiples of 10 and 100.

Materials: (Per

TEACHER)

1 dry erase board

1 dry erase marker

1 dry eraser

Materials: (Per student)

1 dry eraser

Lesson Discussion:

• Review how to multiply whole numbers by 10 or 100.

• Review the properties of multiplication, especially the associative property of multiplication.

• Teach how to multiply one‐digit whole numbers by multiples of 10 and 100. Help the students understand that an equation such as 9 × 70, is the same as 9 × (7 × 10) = (9 × 7) × 10, and the equation 9 × 700 is the same as 9 × (7 × 100) = (9 × 7) × 100.

• The students will learn how to multiply one‐digit whole numbers by multiples of 10 within the range of 10 to 90, and by multiples of 100 within the range of 100 to 900.

PART A:

Procedure:

Step 1: Ask the students if they can find the product of the multiplication problem below. Tell the students to copy the expression shown below on their dry erase board.

3 × 50 =

Step 2: Explain to the students that since 50 = 5 × 10, we change the value of 50 in the multiplication problem to 5 × 10.

3 × (5 × 10) =

Step 3: Tell the students that when using the associative property of multiplication, we learn that in an expression solely involving multiplication, the grouping or order of performing operations does not affect the final answer. Thus, for the multiplication sentence shown in step 2, we can either find the product of 5 × 10 first or find the product of 3 × 5 first.

3 × (5 × 10) = (3 × 5) × 10

Step 4: Tell the students to try finding the product of 3 × 5 first and then see what happens to the multiplication problem.

Step 5: Tell the students that since 3 × 5 = 15, the multiplication becomes an expression involving multiplication by 10.

(3 × 5) × 10 = 15 × 10

Step 6: Tell the students to find the product of 15 × 10 using their knowledge of multiplying whole numbers by 10.

15 × 10 = 150

Step 7: Explain to the students that they could solve the problem (3 × 50) by just mentally multiplying 3 and 5, and then adding a zero. Explain that adding the zero is the same thing as multiplying by 10.

Step 8: Tell the students to erase their boards and write the expression below.

3 × 500 =

Step 9: Explain to the students that since 500 = 5 × 100, we can change the value of 500 in the multiplication problem to 5 × 100.

3 × (5 × 100) =

Step 10: Tell the students that when using the associative property of multiplication, we learn that in an expression solely involving multiplication, the grouping or order of performing operations does not affect the final answer. Thus, for the multiplication sentence shown in step 9, we can either find the product of 5 × 100 first or find the product of 3 × 5 first.

3 × (5 × 100) = (3 × 5) × 100

Step 11: Tell the students to find the product of 15 × 100 using their knowledge of multiplying whole numbers by 100.

15 × 100 = 1,500

Step 12: Now explain to the students that they could solve the problem (15 × 100) by just mentally multiplying 15 and 1, then adding two zeroes. Explain that adding two zeroes is the same thing as multiplying by 100.

Step 13: Let the students practice by using steps 1 to 6 to find the product of the multiplication problems shown below.

6 × 40 =

8 × 300 =

PART B:

Materials: (Per group of 4 students)

1 set of “dominoes” from Domino template

Teacher Preparation:

Step 1: Cut out 1 Domino template for each group of 4 students.

Procedure:

Step 1: Divide students into groups of 4. Distribute 1 set of dominoes from the Domino template to each group. Tell the students to shuffle the dominoes and to each take 4 at random.

Step 2: Whoever has the domino with "Domino #1" written on it drops the first domino. Students take turns dropping a domino that that matches the left or right of the domino(es) already on the table. If a student does not have a domino that matches, the next student tries to make a match. The dominoes can be matched either vertically or horizontally.

MA.3.FR.1.2 – Represent and interpret fractions, including fractions greater than one, in the form of m/n as the result of adding the unit fraction 1/n to itself m times.

OBJECTIVE: Students will learn how to build fractions, including those greater than one, using unit fractions.

MATERIALS: (Per Student)

2 sheets of paper (8.5 × 11 inches, white)

2 sheets of construction paper (8.5 × 11 inches, any color)

1 box of crayons (shared with group of 4 students)

1 pair of scissors (shared with group of 4 students)

LESSON DISCUSSION:

• Review the concept of fractions with the students. Recall that a fraction of the form 1/n represent a fraction that is one part of a whole divided into n equal parts.

• Recall that the number above the fraction bar, called the numerator, represents equal parts of a whole.

Procedure:

Step 1: Instruct the students to take 1 sheet of construction paper and fold it horizontally and then vertically so that each rectangular fold represents 1/4 of the paper. Tell the students to fold the paper horizontally again, thus dividing each 1/4 into 2.

Step 2: Tell the students to open the construction paper. Instruct them to use a pair of scissors to cut along the folds on either side of the construction paper.

Step 3: Explain to the students that since they divided one whole paper into 8 equal parts, 1 part represents 1/8 of the whole. Tell the students to use a crayon to label each cut piece of construction paper as 1/8.

Step 4: Instruct the students to repeat steps 1 to 3 on the other construction paper. Ultimately, each student should have 16 sections, each labeled 1/8. Tell the students to set these pieces aside.

Step 5: Instruct the students to take 1 sheet of paper and fold it horizontally and then vertically so that each rear fold represents 1/4 of the paper. Tell the students to fold the paper horizontally again, thus dividing each 1/4 into 2.

Step 6: Tell the students to open the paper and use a crayon to trace the folds of their paper.

Step 7: Instruct the students to repeat steps 5 and 6 on the other sheet of paper. Ultimately, each student should have two sheets of paper, each divided into 8 equal parts.

Step 8: Instruct the students to color 5 boxes on one of the sheets of paper with a crayon. They can pick any boxes to color.

Step 9: Instruct the students to take pieces of construction paper and cover the colored portions of the paper. They should only use 5 pieces.

Step 10: Explain to the students that since each piece of construction paper represents 1/8, and they used 5 pieces to cover the colored portion of the paper, which represents 5/8, then five pieces is equivalent to 5/8.

Step 11: Instruct the students to color 8 boxes on the other sheet of paper with a crayon.

Step 12: Instruct the students to take the pieces of construction paper and try to use as few pieces possible to cover the colored portion of the paper. They should only use 8 pieces.

Step 13: Explain to the students that since each piece of construction paper represents 1/8, and they used 8 pieces to cover the colored portion of the paper, which represents one whole, then eight 1/8 pieces is equivalent to 8/8, or one whole.

Extension Activity

Step 1: Instruct the students to place the two sheets of paper side by side and ask them to identify the shaded parts. They should say 13/8, or 1 whole and 5/8.

Step 2: Ask the students how many pieces of construction paper they think are needed to cover the colored portion of the papers. They should say 13 pieces.

Essential Question for Discussion or Journaling:

• Define the terms fractions, numerator, and denominator with the students.

• Show how to compare fractions.

• Explain how to identify equivalent fractions by observing and looking at their relative sizes.

Part a:

Teacher preparation:

Step 1: Copy and cut out 1 square from the square template for each student.

Step 2: Use a ruler to draw 4 × 4 squares onto the transparency sheets. Fit 4 squares onto each transparency sheet.

Step 3: Divide the transparency squares in the following manner so that each student has a transparency square that shows 1/2 , 1/3 , 1/4 , 1/6 , 1/8:

Step 4: Pass out the materials to each student.

Procedure:

Step 1: Explain that the transparency divided into 2 equal sections is the “ 1/2 square fraction sheet.”

Step 2: Explain that the transparency divided into 3 equal sections is the “ 1/3 square fraction sheet.”

Step 3: Explain that the transparency divided into 4 equal sections is the “ 1/4 square fraction sheet.”

Step 4: Explain that the transparency divided into 6 equal sections is the “ 1/6 square fraction sheet.”

Step 5: Explain the transparency divided into 8 equal sections is the “ 1/8 square fraction sheet.”

Step 6: Instruct the students to take the paper square template and place the 1/2 square and the 1/4 square fraction sheets on top of the paper. Tell the students to make sure that the paper template square and the squares on the transparencies are aligned.

Step 7: Ask the students to observe the fractions. Explain that 1 section of the 1/2 square is the same or equivalent to 2 sections of the 1/4 square. This means that one 1/2 is equivalent to two 1/4 or 2/4.

Step 8: Let the students use different combinations of fraction sheets to identify equivalent fractions. Suggest that students use the 1/3 square and 1/6 square, or the 1/4 square and 1/8 square, when trying to find equivalent fractions. The students will write the equivalent fractions they can identify on their sheets of paper.

Part B:

Materials: (Per group of 4)

1 set of Fraction Circles

1 dry erase board

1 dry erase marker

1 dry eraser

1 one minute sand timer

Procedure:

Step 1: Tell the students to empty the bag of fraction circles in front of them.

Step 2: Explain to the students that they should make as many 1/2 circles as possible. Tell the students to write down the fractions that equal 1/2 on their board.

Step 3: For every 1/2 circle that the groups create, they get 1 point. The group with the most points at the end of a minute is the winner.

Part C:

Materials: (Teacher)

1 sheet of paper

1 pair of scissors

1 marker

Materials: (Per group of 4)

1 set of Fraction Circles (1/2 , 1/3 , 1/4 , 1/5 , 1/6 , 1/8 , 1/10 , and 1/12)

Procedure:

Step 1: Tell the students to empty the bag of fraction circles in front of them.

Step 2: Have the students separate the yellow circle (1 whole) and place it in the middle of the group.

Step 3: Have the students take turns selecting 1 fraction piece and placing it in front of them until there are no more fraction pieces in the pile. Some students will have more fraction tiles than others.

Step 4: Tell one of the students who have the brown (1/2) fraction piece to place it onto the yellow circle (1 whole.) The students in the groups continue clockwise from that student and attempt to make a 1/2 circle with the pieces that they chose.

Step 5: The student with the least amount of fraction pieces after making as many halves as possible is the winner.

Extension Activity

Step 1: Divide a sheet of paper into 2 halves using the scissors. On half of the paper, write a large number 0, and on the other half, write a large number 1.

Step 2: Call 7 students at random. Tell the 7 students to stand in a line, with each student standing equal distance from the other.

Step 3: Give the paper with the number 0 to the first student in the line and the paper with the number 1 to the last student in the line.

Step 4: Ask the 5 students not holding a number which fractions they would represent on a number line, what fraction would they represent. The answer should be 1/6 , 2/6 , 3/6 , 4/6 , and 5/6.

Step 5: Continue repeating steps 2 through 4 using 5 students, 9 students, and 11 students.

MA. 3.AR.1.1 – Apply the distributive property to multiply a one-digit number and two-digit number. Apply properties of multiplication to find a product of one-digit whole numbers.

OBJECTIVE: Students will learn how to identify the properties of multiplication and apply the properties as strategies in solving multiplication and division problems.

MATERIALS: (Per group of 4 students)

1 set of Properties of Multiplication Cards

LESSON DISCUSSION:

• Explain the identity property of multiplication. Help students understand that the multiplicative identity is 1. It means that any number multiplied by 1 is itself. Example: 8 × 1 = 8 or 20 × 1 = 20

• Explain the commutative property of multiplication. Help students understand that in multiplication, the order in which 2 numbers are multiplied does not matter. Example: 3 × 6 = 6 × 3 or 12 × 4 = 4 × 12

• Explain the associative property of multiplication. Help students understand that in expressions solely involving multiplication, the order of performing an operation does not matter. Example: (2 × 9) × 4 = 2 × (9 × 4) or (3 × 2) × 5 = 3 × (2 × 5)

• Explain the distributive property of multiplication. Help students understand that the distributive property holds on multiplication over addition. Tell the students that the sum of products is equal to the product of sums. Example: 12 × 3 = (6 × 3) + (6 × 3) or 17 × 5 = (10 × 5) + (7 × 5)

Part A:

Teacher Preparation:

Step 1: Print out side A and B back and front of the Properties of Multiplication Cards handouts so the equations correctly align with their answers and cut them out for each group of 4 students.

Step 2: Divide the students into groups of 4 and distribute 1 set of Properties of Multiplication Cards to each group.

Procedures:

Step 1: Have each group shuffle the playing cards. Have each student in the group select 6 cards. Tell students to make sure that none of their group members can see the "answer" portion of their game cards.

Step 2: One student will go first and it will continue clockwise. The first student will show the equation on 1 of their cards to the student their left. That student has an opportunity to win the card and place it in a "win" pile if they correctly determine what property the equation represents. If the student does not guess correctly, the next student will have a chance to win the card and so on until the card is identified correctly.

Step 3: Have the students continue step 2 until all the cards have been identified. The student with the largest "win" pile is the winner of the activity.

Part B:

MATERIALS: (Per group of 4 students)

1 premade spinner from template

1 deck of playing cards

1 thirty second timer

1 pre-drawn dry erase board (or Write and Wipe holder)

1 dry erase marker

1 dry eraser

1 pencil

1 tally table

Teacher Preparation:

Step 1: Remove the face cards (Jacks, Queens, and Kings) from each deck of cards and shuffle.

Step 2: Print out 1 Spinner template for each group and tape it to the back of the spinner.

Step 3: Create a template on dry erase boards to be used by each team. To create the template, turn the board in a vertical position. Use a permanent marker to draw the illustration shown below. Alternatively, print the illustration and insert it in a Write and Wipe holder.

Step 4: Distribute the materials to each group of 4 students.

Step 5: Each student in the group takes turns spinning the spinner. Depending on where the spinner lands, students draw the number of cards indicated.

Step 6: The students will create a multiplication equation using the cards and the property they selected. Tell the students that the Ace card is equivalent to 1. Students cannot have any of the same numbers. If this occurs, the repeated card must be returned to the deck and a new card must be drawn.

Step 7: The students will locate the appropriate equation template on the dry erase board and use the numbers they drew to fill in the template to correctly represent the property of multiplication they selected. For example, if the student lands on Identity property, they draw 1 card. They will write the value of the card in boxes 1 and 2. For example, if they drew the 6 card, it would look like the following:

If the student lands on Associative property, they draw 3 cards. They will write the value of the first card in boxes 1 and 4. They will write the value of the second card in boxes 2 and 5. They will write the value of the third card in boxes 3 and 6. For example, if they drew the 9, 8, and 4 cards, it would look like the following:

If the student lands on Commutative property, they draw 2 cards. They will write the value of the first card in box 1 and 4. They will write the value of the second card in boxes 2 and 3. For example, if they drew the 9 and 5 cards, it would look like the following:

If the student lands on Distributive property, they draw 3 cards. They will write the value of the first card in boxes 1, 3, and 5. They will write the value of the second card in box 2. They will write the value of the third card in box 4. Box 5 will have to have the sum of boxes 2 and 4 written in it. For example, if they drew the 9, 3, and 7 cards, it would look like the following:

Step 8: Students have 30 seconds to correctly draw the cards and fill out the board. If they successfully do so, they earn 1 point on the tally table. They write an I (for Identity), A (for Associative), C (for Commutative), or D (for Distributive) to indicate which property they got correctly. If they do not answer correctly within the allotted time, it is the next student’s turn.

Step 9: Have the students continue taking turns. The first student to correctly get 2 of each property on the tally table is the winner.

Essential Questions for Discussion or Journaling:

(1) Explain the commutative property of multiplication and give an example.

(2) Explain the associative property of multiplication and give an example.

(3) Explain the distributive property of multiplication and give an example.

Step 2: Have the students place the Chip Collection Cup on the game board with 30 chips inside of it.

Step 3: Instruct each group to place the pawn they selected on the "Start" section of their game board.

Step 4: Tell each student in the group to roll the die once. The student who rolls the highest number goes first.

Step 5: The first player rolls and moves the amount of spaces indicated.

Step 6: Students follow the instructions written on the tile they land on.

Step 7: When a student lands on an equation tile, they must find the missing value that makes the equation correct. Once the correct answer is verified, the student may deduct the number of chips from their chip bag as indicated on the tile and place them into the Chip Collection cup.

Step 8: The students will continue alternating turns until there is a winner.

Step 9: The winner of the game is the first person to reach the finish line with no chips. If students reach the finish line with chips remaining in their bag, they must return to the start. If after each player has reached the finish line, but still have chips in their cup, the player with the least number of chips is the winner.

MA.3.GR.1.3 – Draw line(s) of symmetry in a two-dimensional figure and identify line-symmetric two-dimensional figures.

OBJECTIVE: Students will learn how to identify and draw lines of symmetry of two-dimensional figures.

MATERIALS: (Per group of 2)

1 math geoboard

10 rubber bands

LESSON DISCUSSION:

• Explain what lines of symmetry are. Students should understand that a line of symmetry divides a figure into two mirror images.

• It is important to stress to the students that not because a line divides a figure into two shapes of equal size and same shape means the line automatically becomes the line of symmetry. Cite for example the diagonal of a rectangle. The diagonal divides the rectangle into two shapes of same size and shape but the two shapes are not mirror image of each other.

Part A:

Procedure:

Step 1: Using a rubber band, instruct the students to create a square on their math geoboards.

Step 2: Instruct the students to use an additional rubber band to partition the square vertically into 2 equal areas.

Step 3: Tell the students to hold up their math geoboards when they are done partitioning the square and verify they have done so correctly.

Step 4: Ask the students what they notice about the 2 areas. The students should say the two areas have the same shape and size. The students should also notice that the two areas are mirror images of each other; that is, they can imagine folding the square along the vertical line and the 2 areas will fit over each other perfectly. Tell the students that this vertical line is 1 line of symmetry of a square.

Step 5: Instruct the students to clear their math geoboards and prepare a new square.

Step 6: Instruct the students to use rubber bands to partition the square into horizontally into 2 equal areas.

Step 7: Tell the students to hold up their math geoboards when done partitioning the square and verify they have done so correctly. Ask the students what they notice about the 2 areas. The students should notice they have the same shape and size.

Step 8: Ask the students whether this is another line of symmetry of a square. Let the students justify their answers.

Extension Activity

Step 1: Instruct the students to find the other lines of symmetry of a square.

Part B:

MATERIALS: (Per group of 2)

1 math geoboard

10 rubber bands

Procedure:

Step 1: Instruct the students to create a trapezoid on their math geoboards using 1 rubber band.

Step 2: Have the students partition the trapezoid vertically into two equal areas using 1 more rubber band. The students should get a shape similar to the figure below.

Step 3: Ask the students what they notice about the two areas. Then ask whether this is a line of symmetry of a trapezoid.

Step 4: Tell the students to remove the rubber bands from their Geoboards.

Step 5: Instruct the students to create a rectangle on their math geoboards using 1 rubber band.

Step 5: Have the students find the lines of symmetry of the rectangle. The students should get a shape similar to the figure below.

Step 6: Tell the students to remove the rubber bands once they have identified the correct lines of symmetry.

Step 7: Instruct the students to create an equilateral triangle on their math geoboards using 1 rubber band.

Step 8: Have the students find all the lines of symmetry of the equilateral triangle. The students should identify a shape similar to the figure below.

Essential Question for Discussion or Journaling:

(4) 1 - 9" × 3" (Color 4)

(5) 3 - 3" × 3" (Color 5)

(6) 1 - 4" × 3" (Color 6)

Procedure:

Step 1: Tell the students to use 2 of the rectangular cardstock cut-outs to partition Figure 1 into smaller rectangular shapes.

Step 2: Instruct the students to use the area formula for rectangles to find the area of the 2 rectangles individually using their dry erase grid boards.

Step 3: Explain to the students that since the 2 rectangles do not overlap, the area of the irregular figure is the same as the sum of the areas of the 2 rectangles. Instruct the students to calculate the area of each rectangle to find the area of the irregular figure: 6 × 5 = 30 and 10 × 2 = 20. Now, add the areas of each: 30 + 20 = 50. The area of the irregular shape will be 50 square units.

Step 4: Instruct the students to clear their dry erase grid boards and the rectangular pieces from the irregular shape.

Step 5: Have the students partition Figure 1 again, but this time using 3 rectangular pieces, as shown below.

Step 6: Instruct the students to calculate the area of each rectangle to find the area of the irregular figure.

Step 7: Have the students explain why the areas were the same even though they were partitioned into more pieces.

Step 8: Repeat steps 1 though 7 for Figure 2.

Step 9: Have the students partition Figure 2 into 4 rectangular pieces instead of 3, and repeat the steps again.

Ma.3.DP.1.1 – Collect and represent numerical and categorical data with whole-number values using tables, scaled pictographs, scaled bar graphs or line plots. Use appropriate titles, labels and units.

Part A:

OBJECTIVE: Students will learn how to read information from graphs.

MATERIALS: (Per TEACHER)

1 Bar Graph template on oversized paper

1 Pictograph template on oversized paper

1 Circle Graph template on oversized paper

1 Line Plot template on oversized paper

1 sheet of Data Question handout

1 pair of scissors

1 roll of tape

MATERIALS: (Per GROUP of 4 students)

1 whistle

LESSON DISCUSSION:

• Explain to the students the concept of different types of graphs, including bar graphs, circle graphs, pictographs, and line plots.

• Explain to the students how to read information from each type of graph.

Teacher Preparation:

Step 1: Print one copy of the Data Question handout. Use a pair of scissors to cut each card. Separate the cards into the categories of graphs (Bar Graph, Pictograph, Circle Graph, and Line Plot.)

Step 2: Print one copy of the Bar Graph template, Pictograph template, Circle Graph template, and Line Plot template on oversized paper. Place these graphs onto the classroom dry erase board. Alternatively, you can draw these graphs on the classroom dry erase board so that they are big enough for a large classroom to see.

Procedure:

Step 1: Divide the students into groups of 4 students.

Step 2: Provide each group with one whistle. Tell each group to assign one student who will be the one to blow the whistle.

Step 3: Tell the students that at the start of the activity, the whistle blower and 1 other student from each group will stand in front of the board ready to answer questions that relate to one of the graphs on the board. When either the whistle blower or the other teammate know the answer to the question, the whistle blower will blow the whistle and the first to do so will have the opportunity to answer the question correctly and win 1 point for their team. Keep score on the classroom board.

Step 4: Pick 1 question at random to begin the activity. Have 2 students from each group come up to the board. Call on the first group that blows the whistle. Award a point if the answer is correct. If the groups’ answer is incorrect, another group will have a chance to steal.

Step 5: The group who correctly answered the last question will get to choose the next category (bar graph, circle graph, pictograph, or line plot.) From the chosen category, a new question will be picked from the board.

Step 6: The whistle blower from each group will stay at the board, but a new member from each team will join them to be ready for the next answer.

Step 7: Continue asking questions from the cards until all have been answered. The group with the most points is the winner.

Essential Questions for Discussion or Journaling:

(1) How do you read information from a pictograph?

(2) How do you read information from a bar graph?

(3) How do you read information from a line plot?

(4) How do you read information from a circle graph?

Part B:

OBJECTIVE: Students will learn how to create and draw graphs and plots from data sets.

MATERIALS: (Per group of 4 STUDENTS)

1 dry erase grid board

4 dry erase markers of different colors

1 dry eraser

1 Write and Wipe holder

1 Bar Graph Data Table portion of Data Tables Side A sheet

1 sheet of a Supermarket circular

LESSON DISCUSSION:

• Introduce the students to the concept of creating graphs and plots. Ensure they understand that a graph or a plot represents a set of data, facilitating easy comparison of data sets.

• Discuss the properties and components of a bar graph. Emphasize that a bar graph has two axes, each representing a part of the data. The x-axis represents the data categories, while the y-axis represents the quantity of each category.

• Discuss the properties and components of a pictograph. Ensure the students understand that a pictograph uses images to represent a certain quantity. Pictographs require a legend or key to indicate the value each image represents.

• Discuss the properties and components of a line plot. Ensure they understand that a line plot is displayed on a number line to show the distribution of numerical variables, with each x representing a value.

Teacher Preparation:

Step 1: Make a copy of the Data Table Side A and B sheets for each group of 4 students and place them in the Write and Wipe holder. Explain to students they will only be using the Bar Graph Data Table portion of the Data Table Side A sheet.

Step 2: Place students into groups of 4 and distribute the materials to each group.

Procedure:

Step 1: Tell the students to choose 4 different items from the supermarket circular that they would like to use to complete this activity. This will serve as their data.

Step 2: Tell the students to record the name and cost of each item on the data table, arranged from cost to highest cost.

Step 3: Instruct the students to draw 1 vertical line and connect a horizontal line to it, forming a right angle on their dry erase grid boards.

Step 4: Tell the students to label the horizontal line as “Items from Supermarket Circular,” and write the names of the items they chose.

Step 5: Tell the students to label the vertical line as “Cost.” To make a scale to display the data, instruct the students to divide the vertical line into segments of equal lengths. There must be enough segments to contain the highest priced item in their data table.

$ (Dollar Amount)

$ (Dollar Amount)

$ (Dollar Amount)

$ (Dollar Amount)

$ (Dollar Amount)

Step 6: Tell the students to draw a vertical bar from the horizontal axis above each item name. The bar should be scaled to fit all the items.

Step 7: Give the students time to finish their bar graphs.

Step 8: Just by looking at their bar graphs, the students should answer the following questions about their findings:

• Which item has the highest price?

• Which item has the lowest price?

• What is the difference in price between the highest-priced item and the second highest-priced item?

• How much more or less does one item cost than another item?

Step 9: Have the students answer the questions under the data table as a group.

Extension Activity

Step 1: Ask the students to explain why they believe scales on a bar graph are important to accurately represent data.

Step 2: Below their bar graph, have the students make another bar graph using the same data, but without a scale. Tell them to compare the graphs and explain why their data is misrepresented in the second graph. Explain to students that the graph represents the data as if the prices of the items all differ by the same dollar amount.

Part C:

MATERIALS: (Per TEACHER)

60 red tokens

60 blue tokens

60 green tokens

60 yellow tokens

MATERIALS: (Per group of 4 STUDENTS)

1 dry erase grid board

4 dry erase markers of different colors

1 dry eraser

1 Write and Wipe holder

1 Pictograph Data Table portion of Data Tables Side B sheet

1 brown paper bag

Teacher Preparation:

Step 1: Mix the 60 red, 60 blue, 60 green, and 60 yellow tokens in a pile.

Step 2: Fill each brown paper bag with several tokens. It does not matter how many tokens are in each bag as long as the token colors are mixed.

Step 3: Explain to students that they will be using the Pictograph Data Table portion of Data Tables Side B sheet.

Procedure:

Step 1: Distribute the materials to each group of 4 students, including the bags of assorted tokens.

Step 2: Tell the students to open their bags of tokens and separate the tokens according to color. Ask them to record the number of tokens for each color in the Pictograph Data Table.

Step 3: Instruct the students to draw a table consisting of 2 columns and 5 rows on their grid boards. Tell the students to label the first column “Token Color” and the second column “Number of Tokens.” In the first column, the students should write the available colors of tokens in their bag (blue, green, red, and yellow). Their table should look like this:

Step 4: Tell each group to decide what picture they will use to represent tokens. It can be anything. Then, tell the students to decide on the number of tokens each picture will represent. For example, students can decide that use a picture of a token () to represent tokens, and each picture will represent 2 tokens.

Step 5: Tell the students to add this information at the bottom of their table. Their table should look like the example below:

TOKEN COLOR

NUMBER OF TOKENS

KEY:  = 2 tokens

Step 6: Tell the students to fill the table by drawing the number of tokens for each color using the key as a basis. For example, if there are 20 blue tokens in the brown bag, and the key that the students used was  = 2 tokens, then they should draw ten  in the row labeled “Blue.”

Step 7: Give the students enough time to finish their pictographs.

Step 8: Just by looking at their pictographs, the students should answer the following questions about their findings:

• Which token color has the greatest number in the bag?

• Which token color has the least number in the bag?

• How many more or less red tokens are in the bag than blue tokens?

Part D:

MATERIALS: (Per group of 4 STUDENTS)

1 dry erase grid board

4 dry erase markers in different colors

1 dry eraser

1 Write and Wipe holder

1 Line Plot Data Table portion of Data Tables Side B sheet

Procedure:

Step 1: Distribute the materials to each group of 4 students.

Step 2: Ask each student how many siblings each has. They will then record the findings in the Line Plot Data Table sheet.

Step 3: Once they have finished, tell the students to tally their tables. They will count how many of their classmates have 0 siblings, have 1 sibling, have 2 siblings, and so on.

Step 4: Instruct the students to draw a straight horizontal line on their grid boards. Tell the students to place 6 evenly spaced marks on the number line and label these marks “0, 1, 2, 3, 4, and 5 or more.” Lastly, tell the students to label the number line below as “Number of Siblings.” Their boards should look like the example below:

Step 5: Using the data from their Line Plot Data Table sheet, the students will draw 1 X per student. For example, if there are three students with 1 sibling each, the students must draw 3 X’s above the number 1.

Step 6: Give the students enough time to finish their line plots.

Step 7: Just by looking at their line plots, the students should answer the following questions about their findings:

• How many students have 0 siblings?

• How many students have 2 siblings?

• How many more or less students have 3 siblings than 2 siblings?

• How many more or less students have 4 siblings than 5 or more siblings?

Think Tank: The place values of the digits in a number are used to compare two numbers by starting from the leftmost digit (highest place value), which is the greatest place value. If the digits are equal, the comparison proceeds to the next digit to the right (next lower place value). This continues until a difference is found or until all the digits have been compared. The number with the larger digit at the first place of difference is the greater number.

Think Tank: The numerator is the top number in a fraction, which represents the part that we are considering or have. The denominator is the bottom number, which represents the total number of equal parts. For example, in the fraction 3/4, 3 is the numerator which means we have 3 parts, and 4 is the denominator which means the whole is divided into 4 equal parts.

MA.3.FR.2.1 - Leveled Practice 2 (Page 91)

Think Tank: The 1/2 mark will be positioned identically on both number lines because it represents the same relative position on each scale. On the line from 0 to 1, it's halfway, and on the line from 0 to 2, it's also halfway. Even though the second line is divided into smaller increments, the position of 1/2 remains the same because it's a relative measurement.
