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: Ratio and measurement dimensions
Fluency: Compare numerical ratios using consistent units
Reasoning: Explain which dimensions scale linearly, quadratically or cubically.
Application: Explain why two volume ratios differ
Common misconception: Length, area and volume scale factors differ.

Video brief

Model how to compare length, area and volume ratios. Explain each step; pause for a matching shadow question.
