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: Inverse powers and roots
Fluency: Isolate the subject before taking roots
Reasoning: Justify each inverse operation when changing the subject.
Application: Find a radius from an area formula
Common misconception: An operation must act on the whole relevant expression.

Video brief

Model how to rearrange formulae involving powers and roots. Explain each step; pause for a matching shadow question.
