Watch the video which makes the link between repeated addition and multiplication. It explains that for every repeated addition there are two ways to write the multiplication.

Repeated addition is a key concept underpinning multiplication and helps you make the link from skip counting to the times tables.

When you understand that multiplication is simply repeated addition, you can see why it’s often more efficient to multiply the right numbers together, instead of doing the repeated addition or counting one by one.

For example, calculating 9 x 10 = 90 is more efficient than counting up to 90 or doing 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10.

By the end of the lesson, you should be able to write two multiplications for a given repeated addition statement.
