Watching the Wheels Go 'round and 'round

Why do this problem?

This short problem requires children to be able to convert centimetres to metres, to caculate using units of distance and it will consolidate their understanding of circle circumferences.

Key questions

Possible extension

Learners could tackle the Bike Ride problem which also requires them to use time as well as distance.

Possible support

Some children may find it helpful to find a toy with wheels or a wheel from a construction set, then to mark a point on the wheel and watch it turning.
