Editor's Notes
#3 This is an example problem pair. The best place to start out with these is Craig Barton’s book ‘How I Wish I Taught Maths’. The basic idea is this : they copy down the slide. You do the example, writing on the powerpoint and they copy it down. You then reveal the ‘your turn’ question. They then have a go and you can check they can apply the procedure correctly. It’s a really nice way of teaching, I’ve found. I have left the explanation completely up to you, as I wanted to get away from clicking through explanations, which I’m not a fan of.
