@transum.bsky.social drag and drop exercises are great. I often use them. Indices true/false is another favourite. These are great for student self+study.

A speedy drag-and-drop task for anyone tempted to “solve” an identity. It often reveals other misconceptions too.

I've just spent a little time adding some content to taylorda01.weebly.com, specifically on the 'Stories' page (Alice's Adventures in Wonderland, remarkable prime numbers, a festive activity, Frobenius numbers, and Lagrange's Four Square Theorem).

Any more to be added?

Needed a new project so I’ve decided to make worksheets and accompanying videos to review each Unit of the GCSE Maths course. Unit 1 Higher (Number) just went LIVE on YouTube. I actually think these would be really powerful as a cover lesson. Bit.ly/gcsemathsH1Vid

Always like thinking about how to get students to do something tricky by slowly building up the skill - I hadn't seen many "easier" finding intersections questions so enjoyed making my own! #MathsToday #ALevelMaths
Series of questions where students need to find intersections
