Contributor: Alanta’ Story Sample NearPod Lesson In this unit, Kindergarteners will be understanding the concepts of adding and subtracting numbers within ve while using various representations. Students may not understand the de nitions 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, ngers, 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, ngers, mental images, drawings, sounds, acting out situations, verbal
