This lesson includes:

  • one interactive activity
  • two downloadable activities


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 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.
