Representing Adding & Subtracting

Contributor: Alanta’ Story Sample NearPod Lesson

In this unit, Kindergarteners will be understanding the concepts of adding and subtracting numbers within five while using various representations. Students may not understand the definitions of addition and subtraction, so the terms “putting together” and “taking away”, will be used throughout the unit to help them understand the meaning. As a whole, the class will discuss key vocabulary regarding subtraction and addition, including symbols. Students will then explore various visual and hands-on representations such as drawings, linking cubes, counters, fingers, etc. 4. Students then will connect addition/subtraction symbols and equations to their representations. Students are using word problems as a guide to making these representations. During this unit, students will use technology such as tablets and Nearpod, an interactive lesson approach to access content. Also, there are multiple apps that would be used during intervention groups to focus on mastering the skills. Understanding addition and subtraction with the use of word problems is important for society because it helps students understand how numbers and various quantities relate to each other. After grasping the concept, students can then move to adding and subtracting within more complex numbers such as the number ten.

Understanding addition as “putting together” and subtraction as “taking away” is a learning cluster outlined in Common Core Mathematics: Operations and Algebraic Thinking, Standard 1.

Represent addition and subtraction with objects, fingers, mental images, drawings, sounds, acting out situations, verbal explanations, expressions, or equations.

Analyze learners Adding & Subtracting within 5 In the kindergarten class at Gower Elementary, there are 15 students total. There are nine boys and six girls. The students range from the ages of five and six years old. All of the students speak the English language. The students range from Caucasian to African American. Two students have IEPs and spend most of their time outside of the classroom with a paraprofessional to assist them. Gower Elementary is a school that teaches students grades Pre-k through 4th grade located in Nashville, TN. The school is predominately Caucasian, but has a mixed population with African American and Hispanic. Above 40% of students receive free and reduced lunches. Gower Elementary is apart of the most top 30% of diverse schools in Nashville, TN.

To complete this lesson, students will need to know how to count from 1-10. Students should already have an understanding of counting and cardinality.

To complete this lesson, students will need to know how to navigate and operate computers/tablets. They should be able to enter numbers in the particular assignment.

State & NETS*S objectives

K.OA.A.1 Represent addition and subtraction with objects, fingers, mental images, drawings, sounds, acting out situations, verbal explanations, expressions, or equations.

1c- Students use technology to seek feedback that informs and improves their practice and to demonstrate their learning in a variety of ways.

Behavioral Objective:

Given blank worksheets and access to the Nearpod lesson, the students in the kindergarten class will use different objects and/or drawings to represent and demonstrate addition and subtraction problems. There will be multiple opportunities for students to draw and show their thinking using interactive quizzes from Nearpod and the exit activity.

Language Objective:

Key vocabulary: add, plus, sum, subtract, take away, put together, equal, less than, more than

To express understanding, students will use the vocabulary terms to understand and solve word problems. The word problems will consist of the key vocabuary words that will require the students to add or subtract. Students will explain how the pictures they drew correspond with the correct number in the number sentence or word problems. The students will be able to explain how they got the sum or difference.

The vocabulary terms, including symbols will be taught at the beginning of the lesson to give students an understanding of the words they will need to know in order to solve equations and use the correct number of representations to show that specific problem. Students then will connect addition/subtraction symbols and equations to their representations. Students are using word problems as a guide to making these representations. The students will watch a video that will introduce representing addition and subtraction number sentences. After, the class as a whole will discuss key terms and keep them posted up on the board to reference during the remainder of the lesson.

Require learner participation After the teacher explains to the students how to use the interative Nearpod lesson, students will follow along each slide of the lesson with the teacher. The first slide requires students to use their drawing skills to answer the word problem, “Susy picked 4 red apples. She got 6 more from her brother. How many red apples does she have altogether? Draw pictures to represent the problem.” This is the beginning skill for students to understand representation/modeling. The second interactive slide has students match the number of objects with the corresponding number. The students are then broken into pairs. Each student is given a pair of dice and marker, with the subtraction game worksheet. The students are to roll the dice two times and subtract both numbers. The students color in the corresponding circle with the number. The students continue the game until one has “four in a row”. The students are then required to take out a sheet of paper and model their work of the word problem. The students are to type their answers on the collaborative board when they are finished.

Evaluate and revise

Formative assessments used in this lesson were questioning and observing students using the content in Nearpod. Students will demonstrate understanding by solving word problems and using drawings/manipulatives to show their thinking. They will complete up to four word problems during the duration of the lesson. The teacher will monitor students as they work to complete and ask them questions on how they have composed that answer. Asking questions help students to think more critically when it comes to problem solving. The Nearpod app already has the answers programmed and will grade each student individually. All the students are expected to put forth their best effort and answer each question thoroughly, while providing work. When it is time for group work, students are expected to work together and participate. I would like for each student to participate in discussions and be able to explain their work. I will provide positive feedback to students and let them know where there’s work needed to be fixed or done. I will provide extra instructional time if needed for those students.

Summative Assessment (Product):

Summative assessments used in this lesson would be the “adding and subtracting in winter worksheet”. This worksheet requires students to use representations to solve the equations. The numbers used in the equation are between the numbers one and five. This is a milestone for kindergartners because they have to master the concepts up until the number 5 before they begin working on larger numbers. The worksheet includes using objects and drawings to show their addition or subtraction. The student’s work will document the student’s mastery of the standard, “Represent addition and subtraction with objects, fingers, mental images, drawings, sounds, acting out situations, verbal explanations, expressions, or equations.”
