Integer Addition and Number Line Concepts

Mr. Wooly introduces a lesson on using number lines to model integer addition. He provides examples of adding positive and negative integers, explains the commutative property, and discusses absolute value. The lesson includes modeling expressions on a number line and using diagrams to understand sums. The video concludes with homework instructions.

What is the main focus of the lesson introduced by Mr. Wooly?

• Subtraction of integers

• Multiplication of fractions

• Division of decimals

• Addition of integers using a number line
