LO: I can use column subtraction with no exchange.


Last week we recapped column addition and I was really impressed with the work I saw so well done!

This week we are recapping column subtraction. I have done this in the same format of building it up. Starting with the process without an exchange, then with one exchange and then with more than one exchange. We then finished off with problem solving.

Today we are starting with recapping the process. There is no exchange in these calculations.

There is challenge 1, 2 and 3, you need to choose one of the challenges. Year 3 you should aim for Challenge 1 and 2 unless you want to challenge yourself then you could try challenge 3 after challenge 2.
