Here is a cube.

If you had two cubes, you would have double.

Double means two lots of something.

For example, double one is two.

1 + 1 = 2

Here is a set of five toy cars.

If you double this, it makes this many:

Double five is ten.

5 + 5 = 10

Top tip

You can double a number by adding it to itself.

For example, double four is the same as saying 4 + 4.

4 + 4 = 8

Practise doubling numbers and representing them.

Eva has three cakes.

Can you draw how many cakes Eva has after she has doubled them?

Doubles are always even numbers and end with 0, 2, 4, 6 or 8.
