Averages - mean
Key Stage: 3 ★★
What combinations of 3kg and 8kg weights can you find that have a mean weight that is a whole number of kilograms?
This problem offers students a chance to consolidate their understanding of average as a central measure, representative of the set.
It also offers a chance to rehearse the key mathematical processes of exploring, conjecturing, generalising and justifying.
This resource has comprehensive teachers' notes and resources, linked from the problem page. This includes possible approaches and key questions, as well as possible support and extensions.
