Exploring Integer Addition Screencast

Lesson: Exploring Integer Addition Screencast

Intended Audience: 7^th Grade Students

Objectives: After completing this lesson, students will be able to represent addition expressions of real-world integer scenarios. Students will also be able to create their own real-world scenarios given an addition expression including integers. (7.NS.A.1)

Rationale: Before getting into strategies for adding integers, it's important for students to understand the key words or phrases that give away whether a number is positive or negative. For example, words such as "won, increased, gained, and earned" represent positive numbers or positive integers. On the other hand, words such as "decreased, lost, and owed" represent negative 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 remainder of the school year. 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.
