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?
I think 49
Or 124
Prove it!
