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: Perpendicular height and formula substitution
Fluency: Find areas and missing dimensions
Reasoning: Explain a decomposition and identify the perpendicular height.
Application: Calculate material required for a shaped panel
Common misconception: A sloping side is not automatically the perpendicular height.
