Preamble
Discussion, especially establishing the initial strategy, is an important aspect of the task. It also gives pupils the opportunity to practice their previously learned skills of calculating measures of location.
Possible content
Calculating and interpreting measures of location and also the range in order to make decisions.
Resources
Calculator in order to work out means.
Solution/Notes
Pupils’ own decision based on use of measures of location. Overall, because of its smaller range and not that much greater times, Wood Street is the better choice.
