Understanding Integers and Absolute Values

Mrs. Lopez introduces rational numbers, focusing on positive and negative numbers, their positions on the number line, and the concept of absolute value. She explains how to add integers using a number line and introduces the concept of additive inverse, emphasizing that opposite numbers sum to zero. The lesson concludes with a summary of key points.
