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: describe a feature hidden by a view as NOT VISIBLE rather than absent, and ask for a better safe view. Proposed codes: AC9SFU01 (model reasoning), AC9SFH01, AC9SFI03. Prepare: N1/N2 lower-page cut-off, Notebook claim C, two-pair log, Card 147.
Locate · 3 min. Show that the bottom of N1/N2 is cut off in the invented notebook.
Claim · 4 min. Read “N1 has no roots because none are drawn.” State that the notebook supplies no lower view.
Model · 5 min. Record “roots NOT VISIBLE IN THIS DRAWING”; do not add a hidden root to the evidence record.
Child try · 7 min. Card 147 routes rewrite the claim and suggest an approved fuller real view or source question rather than pulling up a plant.
Probe · 4 min. Ask if the same “not visible” wording works for a photo cropped above an animal's feet; child preserves the image limit.
Exit · 2 min. Save precise unknown, safe next question and source label.
