What is it?
I am a huge fan of increasingly difficult questions, and this particular sheet on mean average is just one example of the exercises available.
The concept is simple yet effective. Students are presented with a series of questions on mean average which get progressively more difficult. Incorporating a wide range of topics, this task encourages pupils to make connections between key subject areas while allowing them to fully experience the positive effects of interleaving. And, even better, the answers are provided, helping to make marking a dream!
How can it be used?
Learners benefit most from this exercise if they are familiar with the basics, so I’d suggested introducing this worksheet at the end of a topic unit.
Alternatively, why not set these questions as part of a revision task? The structure of this activity enables you easily identify the areas that pupils are struggling with, allowing for planned intervention where necessary.
