Question

Each of the following pairs of diagrams shows a first and second step that could be used to represent a multiplication problem. For each pair, write a multiplication problem and its solution.

Answer 1

We will see that the first diagram represents a multiplication of 2 by 3, and the second one represents a multiplication of 6 by 4.

How to model the diagrams?

Let's look at the first diagram. First, we have a rectangle divided into 3 parts. Then it is divided into 6 parts.

We can think that each of the first 3 parts is multiplied by 2, then we got:

3*2 = 6

So this represents a multiplication by 2.

For case b, we can see 6 circles, and each one of these generates 4 parts, then we have a multiplication by 4.

6*4 = 24

On the left side, we have 6 individual elements, and on the right side, there are 24.
