Understanding Absolute Values and Inverses

This video covers module two, lesson one, focusing on how opposite quantities combine to make zero. Students learn to add positive integers by counting up and negative integers by counting down. The concept of additive inverses is introduced, and students practice using a Venn diagram and number line exercises. The lesson includes an integer game to reinforce understanding, followed by a summary and problem set.
