V06 · Complete staff assessment

Use an estimate without overstating what it decides

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.

V06A · Complete held case

Whole neutral prompt

4 pretend activity kits cost a made-up $19 each plus one $3 fee. Budget $80. Round both prices up to whole tens for a check. Explain whether that check decides affordability; then calculate exactly.

Specific criterion

Explain the direction and purpose of rounding, then use an exact total when an estimate cannot settle a close budget question.

One acceptable staff response

Upper check 4 × $20 + $10 = $90. It exceeds the budget but cannot alone prove an overrun. Exact cost $79, leaving $1.

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

The budget changes to the exact total, $79; the prices do not change. Is the plan within this new budget? Explain the role of the same upper estimate.

Changed practice staff model

It fits exactly with $0 left. The upper estimate stays $90; it is a check, not the paid total.

5 pretend workshop packs cost a made-up $17 each plus one $6 fee. Budget $90. Round both prices up to whole tens for a check. Explain whether that check decides affordability; then calculate exactly.

Specific criterion

Explain the direction and purpose of rounding, then use an exact total when an estimate cannot settle a close budget question.

Upper check 5 × $20 + $10 = $110. It exceeds the budget but cannot alone prove an overrun. Exact cost $91, over by $1.
