... of the same size) with the minimum number of cuts? For example, to cut a pancake into four pieces, four cuts could be made, each starting at the center and going to the edge. But it would be much simpler to make just two cuts to cut it into four pieces. The maximum number of pieces that can be creat ...

... numbers. They show how the square numbers can be calculated by adding odd numbers. • Allow the students time to prove that this happens for 72, 82, 92 and 102.(1+3+5+7+9+11+13+15+17+19). • This can then be extended so that they students can predict how many odd numbers will be in 152, 202 and 372. ...
