In the maths group, we have been learning about tidy numbers. How tidy numbers work to say that you have 49+25. What you would do you would get 49+1 and that would make 50 and then you would add 49 and that would be 75. And then you would - 1 and that would be 75 and that is a better way to add and subtract.
Hi Milly
ReplyDeleteHow has learning about tidy number helped with your Maths? I wonder can you use tidy numbers when you are doing subtraction as well?
