## CHAPTER 8: MULTIPLICATION

**Lesson 7: Solving Problems by Making a Model **

**Goal**

Use a model to solve a multiplication problem.

**Instructions for Use**

Rectangle Multiplication displays arrays of squares on a grid to help you model and solve multiplication problems.

To change the array shown to model another multiplication problem (or array), click and drag the black square shapes at the left side and bottom of the screen to other positions (numbers).

The Mad Math Game - Multiplication provides you with multiplication problems that can be solved by using arrays.

Click “Start,” then read the multiplication problem. You may wish to model the problem using arrays on paper, using counters, or using Rectangle Multiplication. Type your answer in the white box, then click “Total” to check your answer.
