This activity may be carried out with step by step guidance, or by allowing the student to follow their own method of solution. The approach should be chosen in sympathy with students' skills and depth of understanding.


When a student suggested that boys have bigger feet than girls and another student said it was just a matter of how tall you are if your feet are bigger, the teacher decided to launch an investigation.

The class collected data from all their year group. They made response cards on coloured paper to allow them to sort and to make graphs of the results. Using these cards, can they say that boys feet are bigger than girls feet? Or, is foot size related to height?

Choose one of these questions to investigate. You may use the data provided, or survey/measure your own class.
