Students will discover for themselves how to find the mean from a grouped table. They will then get lots of practice with it whilst trying to find the patterns in each puzzle in the collection.
They are very rich tasks, with a low entry point (students only need to know how to find the mean of a set of numbers) and an extremely high ceiling (involving sequences and series).
Very easy to differentiate for different abilities (either skip pattern 10 or add the brainbox questions).
The task ends with a paired activity where students create their own patterns.
