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

Warm up

Start with quick number facts or a counting game to build fluency and connect to the last lesson.

25 minutes

Model and practise

Show the new idea with objects, pictures and number lines, then work through examples together before your child tries some alone.

10 minutes

Check for mastery

Finish with a few targeted questions or an explain-it-back task that shows what is secure and what to revisit.
