Can your students solve a tricky GCSE question using the equation of a circle? There’s only one way to find out!

The latest edition of my **GCSE Maths Question of the Week** series is a challenging question on circle theorems provided exclusively for my **Diagnostic Questions** website by OCR, but suitable no matter which awarding body you are following.

Here is one suggestion for using this resource:

- Print out the worksheet for use as a starter in lessons, or a homework.
- Discuss your students answers and explanations, their reasons for the incorrect answers, and their choice of alternative wrong answers
- Use our data analytics to see how the rest of the country performed on this question, and view alternative student explanations
- Set your students the entire quiz that this question comes from as a follow-up activity
- Direct your students to the Topic section on my website, where they will find videos, worksheets and extension material on this topic.

All of this is free.

At our school we are using this once a week with our Year 11 classes. I really hope you and your students find it useful.
