## Lesson: Multiplying and Dividing With Negative Integers

Introducing the Concept

In order to help your students understand and remember the rules for multiplying and dividing integers, you should connect the rules to three key ideas: (1) multiplication can be thought of as repeated addition; (2) multiplication is a commutative operation; and (3) division is the inverse operation of multiplication. Having students explore patterns with negative integers will also help them justify the rules.

**Prerequisite Skills and Concepts:** Students should be familiar with the idea that multiplication can be thought of as repeated addition and that division is the inverse operation of multiplication.
