Averages

This list is aimed at the lower end of KS3. The resources are suitable for pupils who have not learnt about averages before. I would suggest using the resources in the order I have listed them. The first 2 resources are good for introducing the topic, teaching it, giving examples and the pupils having a go at questions. The third resource does the same but from a functional point of view. The other resources are all interesting cross-curricular functional ideas to do with pupils that show them the relevance of averages. This unit of work could take 3 or more lessons, depending on how many of the cross-curricular resources you choose to use.

What Is an Average?

This resource comes from the Census At School website. It is a good way of introducing the mean, median and mode to pupils for the first time. It also introduces pupils to using a spreadsheet for performing the calculations, so they can then analyse their results. Data is provided in a file, but you could also collect your own or go to the website to collect different data.

Issue 84: A Resource for the Classroom - Averages Mystery

Once pupils have understood how to calculate the mean, median and mode this resource will present a challenge to them. Pupils have to solve a set of clues to work out what the original data was. This is good for developing their problem solving and thinking skills and suitable for paired/group work.

Pixel Perfection

Once pupils have grasped the basics of calculating averages this resource provides an interesting application in real-life for them. Pupils have to work out the optimum viewing distance from a TV, dependant on the pixellation of the screen. This resource gets pupils working interactively in groups, using their averaging skills. A suggested lesson plan is in the teachers notes file. The other files contain pictures of different degrees of pixellation for the pupils to investigate.

Helicopter Seeds

Another good resource suitable for when pupils have got the basics of calculating averages. A suggested lesson plan is included in the teachers file. Pupils make helicopter seeds, flight test them, record and analyse the data. This is done in groups. The pupils then modify their seeds, flight test them, record and analyse this new data and draw conclusions based on their findings which can then be presented to the class. There is a helicopter template and data recording worksheet provided.
