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: Compass use and angle vocabulary
Fluency: Angle bisectors and a 60-degree angle
Reasoning: Explain which equal distances the compass arcs establish.
Application: Construct a figure meeting length and angle constraints
Common misconception: A measured sketch does not replace a ruler-and-compass construction.

Video brief

Model how to bisect angles and construct triangles. Explain each step; pause for a matching shadow question.
