# V04 · Complete staff assessment Connect an efficient strategy to a multiplicative model ## 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. # V04A · Complete held case ## Whole neutral prompt For caption cards for art folders, 4 groups need 13 items each. Find the total using an efficient strategy and explain how its parts appear in the model. ## Specific criterion Partition, double or otherwise use suitable facts and explain why each intermediate quantity belongs to the situation. ## One acceptable staff response 4 × 13 = 4 × 10 + 4 × 3 = 40 + 12 = 52 items. Another valid explained strategy is acceptable. ## 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 Keep 4 groups, with 14 items in each. Use the earlier strategy to find the new total and explain why it changes by 4. ## Changed practice staff model 4 × 14 = 40 + 16 = 56 items. ## Named next lesson If this target needs more teaching, use N13. ### Give the exact material [Complete neutral V04A](../sources/V04A.html) · [Separate four-empty-response page](../own/V04.html#V04A) · [Exactly source-matched paper](../paper/V04A.html) · [Matched family blank SVG](../../assets/aids/P04.svg) · [Complete matching blank alternative](../../assets/aids/P04.alt.html) · [Full next teaching N13](../../supplementary/N13.html) # V04B · Complete held case ## Whole neutral prompt For labels for repair kits, 3 groups need 18 items each.
