## Ideas

Do you remember how multiplication can be thought of as  equally sized groups  ?

### Examples

#### Example 1

Complete the statement below with the missing numbers.

The image shows groups of leaves.

Worked Solution
Create a strategy

Each clover is a group. Count the number of clovers and the number of leaves on one clover.

Apply the idea

There are 5 clovers, and each has 4 leaves.

The image shows 5 groups of 4 leaves.

Idea summary

Groups have the same size if they each have the same number of items.

## Arrays as products

In this video we see how rows and columns (called an array), can be used to solve multiplication.

### Examples

#### Example 2

Select the array that shows the following statement:\quad 3 \text{ times } 7

A
B
C
D
Worked Solution
Create a strategy

3 times 7 can also be thought of as 3 groups of 7.

Apply the idea

The option that shows 3 times 7 is option A because it has 3 rows of 7.

Idea summary

We get the same answer whichever way we look at our array.
