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.

Learner prompts

Codes: AC9M8A02, AC9M8A03. Goal: build and verify an equality plus a constrained inequality in a new fictional batch situation. Prepare: new-case Day20 learner check and public teacher worked key.

  1. Launch · 2 min. Explain the first work tells us what to teach next; the scenario is not a real procurement decision.
  2. Prior example · 5 min. Revisit different Day17 plans at n=6 and the Day18 n≤5 boundary check. Remove example figures before check.
  3. Instructions · 3 min. Ask for an equation, inequality, exact solutions and substitution. Offer a blank balance/graph board without numbers.
  4. Fresh check · 10 min. Give new-case Items 1–2. Allow neutral reading, AAC, large print or tactile symbols. Record content hints separately.
  5. Transfer exit · 3 min. Item 3 asks for an interpretation with a model limit, not a shopping recommendation. Save first response before coaching.
  6. Note · 2 min. Mark equations, inequality direction, graphical relation, verification and context independently. Use later D20 choices with different numbers.

Later: Day20 extra is only for practice after the held-out response.
