Knowing your three times table really helps with your mental arithmetic, which will be handy in everyday life.

Here is the three times table:

Watch the video from Supermovers to help you learn the three times table with Professor Pipette.

Bertie bought 7 boxes of cupcakes. Each box has 3 cupcakes. How many cupcakes has he bought altogether?

Use the array to help you work this out.

3 lots of 7 (or 7 lots of 3) is 21.

3 x 7 = 21

7 x 3 = 21

Take a look at the bar model. How could you work out the missing values?

There are 3 missing values. So 3 x ? = 18.

Use the inverse operation to work out the missing value.

18 ÷ 3 = ?

Let’s share 18 counters into three groups to help.

The missing value is 6.

6 x 3 = 18

3 x 6 = 18

Compare these two number sentences. Which symbol should be added to the box < , = or > ?*

First, you need to work out what each division or multiplication equals.

36 ÷ 3 = 12

3 x 4 = 12

They both have the same answer! Therefore you need to use the equal sign.

Did you know that there is an easy test to see whether a number is a multiple of 3 or not?

If you added up all the digits of the number, and the answer is 3, 6 or 9, it is a multiple of 3!

For example, is 324 a multiple of 3?

3 + 2 + 4 = 9

Yes it is!
