# 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. ## Named next lesson If this target needs more teaching, use N21. ### Give the exact material [Complete neutral V06A](../sources/V06A.html) · [Separate four-empty-response page](../own/V06.html#V06A) · [Exactly source-matched paper](../paper/V06A.html) · [Matched family blank SVG](../../assets/aids/P06.svg) · [Complete matching blank alternative](../../assets/aids/P06.alt.html) · [Full next teaching N21](../../supplementary/N21.html) # V06B · Complete held case ## Whole neutral prompt 5 pretend workshop packs cost a made-up $17 each plus one $6 fee.
