This resource is accompanied by an answer document. It is aimed at students who have been taught to solve problems involving ratio and proportions, proportional change, and successive proportional change. The questions include proportions within real life contexts, such as taxation, and other cross-curricular contexts including scale factor enlargement. A grading system based on the new GCSE specification is suggested, but this resource would be equally useful in the US. The paper can be printed onto a single A3 folded sheet and there are a total of 60 marks. It can be used as a homework or a revision resource, or to assess general understanding at the end of the topic with plenty of extension and differentiated content available.
