Why do this
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
What does circumference mean?
Show me where the circumference of this circle is.
How many centimetres are there in a metre ... in two
How many metres are there in a kilometre?
Which wheel will turn the most during the journey?
Learners could tackle the
problem which also requires them to use time as well
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.
