The activity should be sufficiently open ended to allow the students freedom of choice in their approach. It may be scaffolded with guidance that leads to a solution, and/or the students might be given the opportunity to solve the problem independently. The approach should be chosen in sympathy with their skills and preferred method of solution.

Andrew wants to store his caravan in a shed with clearance of 2.25 m to get into the shed.

The caravan body is 1.85 m high and is on wheels of diameter, 40 cm. He is going to fit a dome ceiling window in the roof of the caravan.
