Hi. I've been recently looking for a maths investigation that we used during teacher training. It's for KS2... Basically the children get a page of squares divided into 4 smaller squares (like a window) and using 3 colours they have to colour in the 4 squares and then keep going until they have covered all possible patterns and colours...does this sound familiar? Does anyone know where I can get info on this as I can't remember how many possibilities there are! I've tried it myself and I think there are 24 but it would be hard on the children if I didn't actually know!! Thank you to anyone who has a look!
