# Learn

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

### Example 1:

Here are some boats.

Let's arrange them into groups to count them.

There are 4 boats in a row.

There are 2 rows.

4 + 4 = 8

There are 8 boats 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.

5 + 5 + 5 + 5 = 20

There are 20 apples altogether.

### Top tip

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