v1 mapping, pending teacher review. Only AQA and Edexcel are mapped so far. The first 3 pilot worksheets and their worked answers are available; remaining worksheets are coming soon. All videos are still coming soon.

Retrieval: Circle radius and perpendicular gradients
Fluency: Circles centred at the origin
Reasoning: Justify a perpendicular or tangent relationship.
Application: Find a tangent equation at a point
Common misconception: Perpendicular gradients are negative reciprocals when finite.

Video brief

Model how to use the equation of a circle and its tangent. Explain each step; pause for a matching shadow question.
