The numbers in the five times table are:

5, 10, 15, 20, 25 ...

I could shift these numbers up by 3 and they would become:

8, 13, 18, 23, 28 ...

In this activity, the computer chooses a times table and shifts it.

Can you work out the table and the shift each time?

Can you explain *how* you worked out the table and shift each time, and why your method will always work?

Levels 1 and 3 include tables up to 10.

Levels 2 and 4 include tables up to 20.

On levels 1 and 2, the numbers will always be the first five numbers in the times table.

On level 3 and 4, the numbers could be any five numbers from the shifted times table.
