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.
Invite: What first evidence is available before help?
Encounter/model: Only unrelated recall if needed: SET0, ADD5, SHOW means5. Do not model the held source or repair.
Own practical action: Offer Fresh E. Capture own first prediction/design/change/reason; approved-device actual entry/run is recorded separately. One meaningful first component may precede another sitting.
Observe/check: Use separate descriptive key after first capture. No new hints/key during capture.
Possible misconception: A matching final number alone does not prove a general input-responsive repair.
Next teaching move: Give specific feedback after first capture, then a different changed batch if teaching is needed.
Use: choose one route, one model or neither where unnecessary. No30-route log or all-context quota. Home/extra 5 is an independent free offer, not required catch-up.
