Target/codes: independently change size of a new five-corner form while holding its shape and frame; AC9AVAFD01, AC9AVAFC01. Prepare: public Check I, I A4, broad five-corner card. Keep the teacher key closed until first response.
- Welcome · 3 min. Say this is a new picture puzzle to inform the next lesson, not a neatness test.
- Access · 4 min. Give two equal frames: the first has a small five-corner form; the second is blank. Read “make a larger version in the second frame while it keeps five corners.” Do not point to an answer.
- Independent plan · 5 min. Child decides what must stay and what will change using a chosen route.
- Child response · 7 min. Child draws, places or directs the second five-corner form and identifies the change. A neutral adult records the first response without adjusting it.
- Self-check · 4 min. Ask if the form still has five corners and which fills more frame. This is a question, not corrective coaching.
- Close · 2 min. Save the first response; only then open the key. The next two lessons explore marks and materials, a different decision.
