Repeated addition

Take a look at these doughnuts, when you see this image what do you see?

We can see two calculations here.

An addition and a multiplication which means two groups of 5 is equal to 10.

5 + 5 = 10

and

2 x 5 = 10

You can rearrange objects to form both multiplication and repeated addition number sentences, and there is more than one way to represent and work out the same calculation.

Now the doughnuts have been arranged in a different way.

What calculations do you see here?

The two calculations here are a repeated addition of

2 + 2 + 2 + 2 + 2 = 10

and a multiplication of

5 x 2 = 10

This means 5 groups of 2.

Example

Here are 14 flowers, have a look at the slideshow to see how we can arrange them into multiplication and repeated addition sentences.
