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.
Goal: connect one bounded statement to raw stops, including interruptions and uncertainty. Proposed codes: AC9SFU02, AC9SFI03, AC9SFI04. Prepare: actual dated run if present or M, claim-limit, Card 97.
Source label · 3 min. Display ACTUAL/date or M MODEL at every stage. Do not substitute M for an actual mixed result.
Re-read · 4 min. Read all valid positions and any interrupted entry aloud in original order.
Model · 5 min. Say of M, “In this invented set, narrow-face tries both stopped at MIDDLE; broad-face stops differed. This does not tell what a real carton will do.”
Child try · 7 min. Card 97 routes point/say/scribe one claim with the supporting exact entries and one unknown. If actual attempts are too few or mixed, “not clear yet” is valid.
Check · 4 min. Offer unsupported N strip 2. Child rejects “always” because four pretend entries cannot carry it.
Exit · 2 min. Keep child's actual wording, source, prompt and uncertainty.
