Addition and Subtraction: Find the Number (1-20)

This worksheet is about changing a story into maths.

Look at the ladybirds on this plant.

Count them.

There are 12 ladybirds.

Now look at this picture.

4 ladybirds have flown away.

How many are left on the plant?

8 are left on the plant.

We started with 12 and 4 flew away.

In maths, this can be written as:

12 - 4

Now 12 - 4 = 8

So 8 are left on the plant.

12 - 4 = 8 tells the story of how many ladybirds are left on the plant.
