Suggested approaches

This task is suitable for individual or paired work, and could also be set as homework. It is useful as a ‘screener’ to identify students who need some revision of the basic processes involved in working with percentages. The activity also involves interpreting the results of calculations, and it is important to stress the importance of this; making sense of results will become increasingly crucial as students progress to more advanced work.

+
Resources/documentation

The resources provided comprise:
 The question paper (students answer the questions on paper / in exercise books)
 An answer sheet for teachers

+
Relevant digital technologies

Students will need access to calculators. They should be encouraged to develop efficient calculator procedures, for example by using decimal multipliers, the memory facility and brackets.

+
Possible extensions

This task forms a suitable introduction to any longer piece of work where students’ facility with percentage calculations will be assumed.
