Watch the tutorial if you need a reminder about subtraction. Remember that we call it exchange, not borrowing (we are exchanging 1 ten for 10 ones, or 100 for 10 tens etc)
Pick the challenge that is right for you! If it is too easy, have a go at the next challenge. Make sure you look for the exchanges before you start calculating (make sure most of your calculations have exchanges!). Remember to write your calculations as columns.
Chilli 1: 2-digit numbers take away 2-digit numbers e.g. 76 - 38 =
Chilli 2: 3-digit numbers take away 2 or 3-digit numbers e.g. 457 - 88 = 534 - 286 =
Chilli 3: 4 - digit numbers take away 3-digit or 4-digit numbers e.g. 7236 - 1879= 7236 - 768=

As well as the activity on the grid, make sure that you read to someone today and think carefully about what you have read (make sure you understand!)
