Why do this problem?
will help pupils become more confident in calculating with units of time. It is also a practical example of optimisation.
The problem could be introduced by projecting the map onto a screen and children could be given copies of the routes.
How long is each route?
Which route is most bendy?
How are you going to decide on the best route?
How many stops would be needed for each journey?
The problem Delia's Routes
might be a good extension. It challenges learners to work in a systematic way to find possible routes.
Having a copy with the routes
will help children get started. Encourage them to work with a partner.
