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: independently apply shape and border rules to a new five-card source, preserve unknown, and represent one entry in three forms; AC9TDIFK02 partial. Prepare:public A, A A4, five matching large physical tokens; teacher key closed.
Welcome · 3 min. Offer a new paper depot puzzle; no outdoor object, timer or device is needed.
Access · 4 min. Read the five new square/oval badges and their dotted/plain/NOT SHOWN borders neutrally; do not sort them.
Independent plan · 5 min. Child decides where each entry belongs under the two different questions.
Child response · 7 min. Save first complete shape and border groups, explicit unknown placement, and one physical-token/picture/symbol match.
Self-check · 4 min. Child traces source IDs and both question labels without an adult placing a solution.
Close · 2 min. Consult the separate key later; after-check practice uses other sources.
