 This is a mathematical snack from the Association of Teachers of Mathematics. This is a game for two players called squares. It's a bit like noughts and crosses, but in this game you have to make a square rather than a line. One player is a nought and the other a cross. The first player to make a square wins. Watch us play the game. Christine, I'm going to start and I'm starting there. I'm going to put my nought there. I'm going to put my cross... Let's have a look... I'm going to put my cross there. I'm going to put my nought there. I'm going to put my cross there. I'm going to put my knot there. Ah, and I am going to put my cross there and I've made a square. There it is, there's my square. Let's play another game. Christine, you may start. Okay, I'm going to start with my knot there. I'm going to put my cross there. My next knot is going to be there. I'm going to put my cross here. My knot is going to go there. And I'm going to put my cross there. And my knot is going to go there and then I have made a square. You have. Well that's how to play the game and now you have a go at playing the game. You might want to work out how many ways of making a square there are. You could alter the game and play until you fill the board and see who's made the most squares. Happy game playing.
