3bExplain how you got answer to 3a.Multiply by 3 or p.
4aEstimate the diameter if the circumference is a certain value.Varies.
4bExplain how you got answer to 4a.Divide by 3 or p.
5Describe the relationship between circumference and diameter.C = pi D or equivalent.

Below are the results for the pupil questionnaires. The key is as follows:

~:correct answer (using three instead of pi on questions 3-5)
+:correct answer (using pi or approximation to pi e.g. 3.14)
.:no answer given

Questionnaires 1 and 2 were completed immediately before and after the activity, and no prior warning of the topic was given. Questionnaire 3 was completed approximately 2 weeks later, again without prior warning.
