Percentage Calculations

This collection contains a wide range of worksheets about percentages aimed at levels 5 - 8 of the new GCSE 9-1 curriculum. Use multipliers to calculate percentages, increase or decrease amounts and see how to use multipliers in repeated change questions ( especially simple and compound interest problems ). The sheets explain the methods used and check understanding as students work through them. Answers are provided. There is also a powerpoint about reverse percentage calculations as it is a topic that students often find particularly difficult to grasp.
