Why do this problem?
requires a systematic approach and a good method of recording. The second part of the problem challenges children to calculate using distance and time.
How do you know you've got all the routes?
How will you record the routes?
Have you written the distances on the picture?
What is the calculation you need to do?
Knowing how long the journey took and the speed she travelled, how can you work out the total distance they went?
Using this and the second piece of information, how far is it between D and E?
Learners could make up a simple map of their own and ask a friend some questions relating to it.
Having a copy (or copies) of the map will help children have a go at this problem.
