Today there are a few options to choose from depending on how confident you are...
You can practise dividing a 2 digit by a 1 digit
a 3 digit by a 1 digit
a 4 digit by a 1 digit.
The 2 digit and 3 digit work is labelled as Year 4 as it is a recap of previous learning, but please feel free to start here if you need to.
Just pick ONE! You don't need to do it all! If you start one and it is too easy, move on up to the next level!
