Some of you might like to take the challenge and sign up for World Maths and Spelling Day. Click on the picture to find out all about it. Make sure you read the rules. Parents you can sign up too, but no prizes if you are a maths whizz and earn a great score. This starts as far as I can see at 12.00am on 1st March and I think goes for 24 hours. I have yet to read all the details myself.
