A full lesson on the classic examination question based on unitary proportion. The powerpoint takes students through how we can very simply change a recipe for 4 biscuits into a recipe for 8 biscuits and then evolves to see how we could perhaps change recipes for 6 into recipes for 8 by scaling down and then up. There are two resources to accompany the lesson, both of which are fully differentiated and,when printed in A4 booklet form, allow the students to write on, including their working. Answers not supplied and the recipes are not real! I usually finish this lesson with the Maths 4 Real video with Ben Shepherd (although I cannot include this video as I do not own it)
