Making arrays

Learning focus

Learn how to make arrays by making equal groups and building them into columns or rows.

This lesson includes:

  • a catch-up quiz
  • a video
  • a learning summary
  • one activity


To get started, let's see how well you know this topic already. Take the catch-up quiz below to find out.


Watch this animation from 1st Level Maths and Numeracy. Fin and Snoot count Meebs by putting them into equal rows and columns.

Fin and Snoot count meebs by putting them into equal rows and using multiplication.

Example 1

Here are some doughnuts.

Let's arrange them into groups to count them.

There are 4 doughnuts in a row.

There are 2 rows.

We can write this as an addition.

4 + 4 = 8

or we can write this as a multiplication

4 x 2 = 8

There are 8 doughnuts altogether.

Example 2

Archie wants to arrange some apples in an array.

He has made a full row and started the other rows. Can you fill in the rest?

How many apples in a row?

There are 5 apples in a row.

How many rows are there?

There are 4 rows.

As a repeated addition this is:

5 + 5 + 5 + 5 = 20

or written as a multiplication

5 x 4 = 20

There are 20 apples altogether.

Top tip

Make sure you have the same number of things in each row.
