Target: child-select data, make three forms and test the matching key; partial AC9TDIFK02 with P01 category revisit. Ready: broad props/cards and blank board; optional willing reader.
- Welcome · 3 min. “You can choose a tiny pretend show message.” Choose two or three WAVE/SHOW STAR/SHOW MOON/FINISH items, or pass. No real safety directions.
- Model · 4 min. Adult invents a different short message and labels its source “Adult model.” Demonstrate how to attach the exact chosen key; remove the model before child work.
- Together · 5 min. Discuss what a reader needs: the intended message, its order and a matching key. A real name/photo is unnecessary. Do not supply the child's choices.
- Child task · 7 min. Child chooses, builds/directs/describes their own message in object, picture and symbol forms. Invite a willing private reader to read it, if desired. Compare actual interpretation with the child's stated message; revise one useful feature.
- Notice · 4 min. Record child-chosen source, representations, key, actual handling/support and actual reader response if any. A described object row remains a described plan until constructed.
- Close · 2 min. Child can enjoy a pretend tabletop show or keep their work private. Keep tomorrow's new check source unseen.
