Cycling and measuring distance challenge

Two cycling-mad pupils meet Paralympic champion Sarah Storey, who sets them a maths challenge related to cycling.

Two cycling-mad pupils meet Paralympic champion Sarah Storey, who sets them a maths challenge related to cycling. They're taken behind the scenes at the National Cycling Centre in Manchester. Can they find out how much further Sarah would cycle if she takes a line further up the velodrome, rather than taking an inner line? From BBC series 3,2,1 Go!

Teacher Notes

Students could discuss in pairs how they think the boys will do the task, then share their ideas with the rest of the class. What equipment will they need? What would their prediction be for the difference between the two tracks? How did the boys' method compare to the students' own? Students could be tasked with drawing a cycle track, and working out the length of the track using another way aside from measuring it (using the circumference of a whole circle and two straight sections). What information do they need? As an alternative, shapes made from semicircles and straight sections could be marked out on the floor. Students who need support can work with a partner to calculate and then measure them using a trundle wheel to compare their answers.
