This lesson focuses on the formal column subtraction method, recapping how the method works and challenging children to start subtracting four- and even five-digit numbers (if they are feeling brave enough!). The main activity will have them competing with a friend to solve calculations with the highest answers to score points whilst the alternative activity will have them sorting calculations into the correct section of a Carroll diagram, depending on their answer.
