Multiplying Negative Integers: Understanding Equal Groups

This lesson teaches how to multiply negative integers by using the concept of equal groups. It introduces models to represent positive and negative integers, such as zero pairs, and explains the use of a product box to visualize multiplication problems. Through examples, the lesson demonstrates how removing negative groups from a neutral field results in positive products, reinforcing the concept that multiplying two negative integers yields a positive result.
