Anzac Biscuit Problems

In Te Ngahere we have been doing maths around anzac. Our problem was that the original recipe makes 30 anzac biscuits, then we had to work out our own biscuit problem. My group had come up with different examples of how to show our evidence, even if we weren’t quite sure if the examples were right. With the anzac biscuit problems we used trebling and thirding because trebling and thirding is easy to understand if you have the right numbers. I knew that if you times 3 by 9 you get 27 so if you times 30 by 90 you get 270, it is easier if you use 3 times tables even though the number is odd. So now you know what 3 times 9 is so you times the original recipe by 9 because the original recipe makes 30 biscuits. I really enjoyed learning different way to solve these problems . I think I did well understanding how to treble and third the recipe to get 270.
