The learning framework

Anatomy of a focused lesson

Each session moves from a clear focus to guided practice and a quick check for understanding.

10 minutes

Retrieve and connect

Start with a short retrieval task on the earlier ideas this topic builds on, so gaps are picked up before they cause problems.

25 minutes

Reason and practise

Work through examples with clear mathematical reasoning and setting out, then move to independent problems in real-world contexts.

10 minutes

Check for understanding

Close with assessment-style questions that show what is secure and what to come back to next lesson.
