Codes: AC9HE7K01, AC9HE7S04, AC9M7N06, AC9E7LY06. Goal: make a conditional choice under one slot/$25 cap, naming monetary cost, possible benefit and opportunity cost. Prepare: fictional optional outreach brief.
- Open · 3 min. Core large-print/text/tactile access is already provided; ask what scarce resources remain for an extra: one showcase slot and $25 discretionary funds.
- Model · 5 min. A practice station costs $18 and leaves
$7; B take-home cards cost $24 and leave$1. Both fit cap. Price is monetary cost; next-best option's possible benefit is opportunity cost under a stated ranking. - Investigate · 8 min. List A's possible immediate-feedback benefit and B's possible repeat-practice benefit; both are unmeasured predictions. Choose two decision criteria without pretending access is optional.
- Choice · 10 min. D18-A/B/C: committee note, ranking cards or cost/benefit board. State rank1/rank2, exact arithmetic, one given-up benefit, condition to verify.
- Check · 6 min. If ranked B>A and B chosen, what is forgone? A's possible immediate-feedback benefit, not $24. Ask what still needs checking before an actual choice.
- Note · 3 min. Record whether price, remaining funds and opportunity cost stayed distinct; recheck with reversed ranking if not.
Later/home: Compare A/B on paper only. No real procurement or family cost disclosure.
