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: transfer two-way table, conditional denominator and claim-scope judgement to a new invented sticker-card case. 25 = 2 + 3 + 10 + 6 + 4.
0–2: State that this public check is new relative to lessons but can be read in advance; locally adapt if prior access matters.
2–5: Offer exact read-aloud, tactile grid, calculator, AAC or scribe without explaining the fresh totals.
5–15: Learners independently answer Check B, preserving first work.
15–21: General reflection after collection: which cell / which group / what absent category / what claim?Routes: count tiles; shaded table; spoken/signed fraction audit.
21–25: Teacher reads the public key and picks a next step based on the learner's actual evidence. Next move: fresh local case for later reassessment if prior prompt access mattered.
Another setting: Invented craft-template cards with a different two-way register. Optional/home: explain given versus all using a made-up fraction, no real survey.
