 This is a mathematical snack from the Association of Teachers of Mathematics for you to enjoy. This is a task which you could think was geometry. So my task is I'm going to draw a square and it's just a rough sketch of a square and I want to divide that square into smaller squares. They must all be squares. Here is one possibility. That's four squares. Or I could do it into more squares. For instance, I could divide squares this way and that's nine squares. But the question arises, can I divide this into other numbers, not four or nine or sixteen? So let's look at this. If we take this one and divide it there. I've got four little squares and three big squares. So I've got four plus three equals seven. I divided that square into seven squares. So the challenge to start with is can you divide a square into let's say eleven squares or twelve squares. And then you might want to move on and see what other numbers of smaller squares you could divide squares into. Go up to about twenty. Sometimes you can't do it at all and sometimes you can do it in lots of different ways. So you could explore that as well. So with this activity, this is your task. Have fun.
