Today we have been investigating how many different ways you can make a square on a chess board.

At first we thought it was 64, but it turns out that there is a lot more.

What if….

• What if the grid was 12 x 12?
• What if the grid was any number x any number?
• Can you find a rule to apply to all grids no matter what the size so that no one has to count any more squares?
