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: Areas of individual faces
Fluency: Exclude internal or joined faces
Reasoning: Explain which surfaces are exposed.
Application: Calculate paint needed for an exposed surface
Common misconception: Joined or internal faces should not be counted as exposed area.
