Notes on using Percentages.xls

This workbook was produced with a GCSE retake class in mind and  provides practice with the basic routines of percentages. Each sheet asks a randomly generated question and checks the students answer. I imagine it being used when all the types of problem have been covered as  revision or consolidation of the topic.

Students could use it independently for revision or during class time instead of  exercises.

A common difficulty of students is that they muddle up one method with another. Hopefully this workbook encourages an awareness of the different types of  problem and builds up flexibility in switching from one type to another.

At first students could be encouraged to work on one type at a time until they are confident with each and then move to switching between types frequently.

I had thought of adding help buttons to remind students of methods but then not everyone uses the same method so it might be confusing. Let me know if you think this would be useful.
