Multiplying Positive and Negative Integers Using a Number Line

In this lesson, students will learn how to multiply two positive or two negative integers using a number line. They will explore the commutative property of multiplication and understand that switching the order of factors does not change the result. The lesson also addresses the common misconception of multiplying two negative numbers resulting in a negative product. By using examples and flipping over the origin on the number line, students will see that multiplying two negative numbers actually yields a positive product.
