Splitting subtraction into tidy numbers...Term 2 09

We are learning how tidy numbers work in maths.
We are learning to make the connections using part whole thinking.

You can see how we make tens!






This group worked incredibly hard today.

Our learning intention: To group numbers and subtract in parts.

eg making tidy numbers using tens. Can you see the hard work? We had to imagine 75-7 and then say we know that if we take away 5, it will look like 75-5=70 and I know that I have to take away another 2, so 70-2= 68. We had to think, visualise and look at tidy numbers. We are learning to think like a 'part whole thinker' . We were very proud of our work!
