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: Fraction of a full turn
Fluency: Find arcs, sectors and sector angles
Reasoning: Explain the relationship between the lengths or regions used.
Application: Calculate a sector perimeter or shaded area
Common misconception: Radius and diameter are different; sector perimeter includes radii.

Video brief

Model how to calculate arc lengths and sector areas. Explain each step; pause for a matching shadow question.
