Teacher copy: This page may include teaching prompts or answer keys. Answer keys in this public library can be viewed by anyone. Give learners a clean prompt, use checks as formative evidence, and change a case locally when prior access matters.
Target/codes: represent the source under a shape question using physical tokens and matching pictures/symbols; AC9TDIFK02 partial. Prepare:A source, B shape bays, C/T symbol cards.
Welcome · 3 min. Ask “Which badges show a circle; which show a triangle?” Name the rule before moving anything.
Model · 4 min. Put physical ID 1 in CIRCLE because its printed picture shows a circle. Badge 5 can still be grouped by shape despite unknown border.
Try together · 5 min. Child places IDs 2 and 3 by shape, with a reason grounded in their source pictures.
Child choice · 7 min. Child completes all five IDs in object, picture or symbol form, directs adult movement if needed, and checks the source position rather than memory.
Notice · 4 min. Save group membership and what was a physical object versus image. This is not a Mathematics count check or real feature grouping.
Close · 2 min. Keep the same badges; tomorrow the question changes.
