Numeracy is a serious issue, but that doesn't mean that we can't have some fun, so we've organised a Numeracy Challenge to celebrate National Numeracy Day this year.
Select the button below. Take the Challenge. Win the T-shirt. Good luck!
Note: you can still access the Numeracy Challenge but the deadline for winning the T-shirt has passed. You are still welcome to play the game but we recommend that if you choose an alias in the game, you don't use your real name or email.
