Target/codes: identify the source's two stated fields, including one border not shown; AC9TDIFK02 partial. Prepare: A illustrated badge source, A material guide, five broad physical stand-ins.
- Welcome · 3 min. Say “These are invented paper badges. They are not things we saw outdoors.” Ask what question the source could help answer.
- Model · 4 min. Point to ID 1: circle shape and solid border. Separate ID, shape and border. Show ID 5's circle is visible but its border is explicitly NOT SHOWN.
- Try together · 5 min. Child matches two physical stand-ins to their pictures and neutral labels; adult reads only the fields printed in the source.
- Child choice · 7 min. Child chooses another ID and shows its known fields by objects, pointing, AAC, drawing or agreed symbols. They place a question mark on any unavailable border.
- Notice · 4 min. Save exact ID/feature claim and route. A fictional badge is no Science observation of a living thing.
- Close · 2 min. Leave the source visible for tomorrow's chosen rule.
