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.

V04B · Complete held case

Whole neutral prompt

For labels for repair kits, 3 groups need 18 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

3 × 18 = 3 × 10 + 3 × 8 = 30 + 24 = 54 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 3 groups, with 19 items in each. Use the earlier strategy to find the new total and explain why it changes by 3.

Changed practice staff model

3 × 19 = 30 + 27 = 57 items.

V04C · Complete held case

Whole neutral prompt

For tokens for game packs, 6 groups need 14 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

6 × 14 = 6 × 10 + 6 × 4 = 60 + 24 = 84 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 6 groups, with 15 items in each. Use the earlier strategy to find the new total and explain why it changes by 6.

Changed practice staff model

6 × 15 = 60 + 30 = 90 items.

Named next lesson

V04D · Complete held case

Whole neutral prompt

For picture cards for learning trays, 5 groups need 19 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

5 × 19 = 5 × 10 + 5 × 9 = 50 + 45 = 95 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 5 groups, with 20 items in each. Use the earlier strategy to find the new total and explain why it changes by 5.

Changed practice staff model

5 × 20 = 50 + 50 = 100 items.
