This is an introduction to Column subtraction aimed at Year 3 (UK) or Second grade (US). It starts of with basic examples and moves to explain exchanging ten, hundred and both tens and hundreds in a visual, child friendly and easy to understand way. The children will have great fun defeating my mathematics villain, Dr Doom! It has four worksheets which correspond to a code that the children use to defeat each stage of Dr Doom's plan. The PowerPoint has logical break off points meaning it's perfect to complete over multiple sessions.
I have tried to provide children with a clear understanding of the methods underpinning column subtraction which relates directly to the new style mastery curriculum. I hope the children have as much fun with it as my students did!
Happy learning :)
