LO: I can use column subtraction with more than one exchange.

 

Hopefully, you remembered the exchange yesterday and are ready to move onto more than one exchange. If you are not sure then carry on practising with one for now.

If you are ready then today we are doing more than one exchange.

Again, 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.
