In common with most Maths teachers, I love Don Steward’s site Median for the fantastic range of quality resources and ideas. All the ideas in post come from here. I have taken some of them and put them into a PowerPoint with some solutions. As teachers, we should do the Maths that we are asking our students to do in lessons. Which is, I guess, why most of the resources on Median don’t have solutions with them. However, in the midst of a busy term, lesson planning has to be time-efficient and so I have added a slide in here with some possible solutions (there may be more elegant options). The idea being that lesson planning is then a case choosing how to present this and involves deleting pieces of this solution which is much quicker that creating them from scratch.
