Compare equal quantities rather than ticket prices

Local four criteria

• Formulate: identify what is known, what is unknown, and what the quantities count; choose a model that matches the supplied situation.

• Solve: connect a representation with a correct number sentence and use a suitable efficient strategy; distinguish selected no-calculator evidence from a digital check.

• Check: choose an estimate, inverse operation or second representation appropriate to the day; explain its limits for a close budget decision.

• Interpret: give the result with a contextual unit and a usable conclusion that respects the stated constraints and assumptions.

Record real exposure, reasoning and support. A/B/C/D choices are not independence or official A–E bands. Hide staff models before own work.

V07A · Complete held case

Whole neutral prompt

Exactly 18 blank picture cards are required. Offer A: 6 for a made-up $18; B: 3 for $12. Whole packs only and no extras. Compare full costs and explain the cheaper plan.

Specific criterion

Use whole packs to supply the same target quantity and compare full costs with contextual units.

One acceptable staff response

A:3 packs,18 items,$54. B:6 packs,18 items,$72. A costs $18 less.

Support/interpretation

Treat the worked model as one acceptable example, not an exhaustive answer list. Accept an equivalent accurate representation and explanation. Record actual reasoning, help and units; do not infer mastery from a copied answer.

Separate changed practice

Exactly 36 items are now required, with the same whole-pack offers. Compare again.

Changed practice staff model

A:6 packs/$108; B:12 packs/$144; quantities both 36.
