Exploring Integer Addition Podcast

Lesson: Exploring Integer Addition

Intended Audience: 7^th Grade Students

Objectives: After completing this lesson, students will be able to show addition of integers on a vertical and horizontal number line. Students will also be able to show addition of quantities by showing positive or negative direction from one quantity to the other. (7.NS.A.1)

Rationale: The 7^th grade math curriculum begins each year with integers. Integers are a vital standard and skill all 7^th graders need to master because we constantly refer back to and use them throughout the school year. For example, we incorporate integers into equations, inequalities, ratios and proportions, geometry, etc. This lesson is just a brief introduction to two methods students can use to add integers. Instead of just giving students the basic rules for adding integers, in this lesson they can explore numerous ways of getting the correct answer. Once students have learned all of the strategies for adding integers, they can then choose whichever one works best for them. The podcast is split into 2 parts: part 1 covers adding integers with number lines and then gives students time to practice on their own and with a partner. Part 2 then covers using plus and minus signs for adding integers with again time for students to work independently and reflect on their answers with a partner. Both of these lessons can be differentiated to meet the needs of all learners. In part 1 students can be given number lines they can draw on with dry erase markers, and in part 2 students can be given chips with plus and minus signs on them.
