What is it?

Finding a resource to fit a specific need can sometimes be a struggle. While planning a lesson on calculating the estimation of the mean from a frequency table, I found myself wanting examples for my class – lots of them. Thankfully, this resource provides just that.

Comprising of a simple spreadsheet, this fully interactive generator creates brand-new questions at the click of a button. Best of all, you can reveal each solution step-by-step, helping to fully cement your students’ understanding.

How can it be used?

Why not generate examples for your learners to practise before checking the solutions together? Alternatively, screenshot the incomplete tables and walk through the necessary steps needed to complete the calculations.

To stretch more-able students, I’d suggest projecting multiple questions on the board at any one time. This way you can ensure that all pupils are practising at their own pace.
