MODEL collection: 3 complete groups of 30 pieces and 12 loose pieces. Two fictional material batches are 238 and 346 pieces. Stock is 600 pieces. A ticket reports the combined batches as 58 pieces. No real class count, purchase or event is asserted.
Choose usual communication, exact scribing, private/untimed response, rest or pause. No physical action is inferred. A blank paper or typed page can replace this aid; keep each prompt separate.
1. Estimate the collection using a known group. Explain your clue; keep an estimate different from an exact count.
Own response: [genuinely empty; no worked answer]
2. Before exact addition, give a useful estimate of the two batches and explain a benchmark.
Own response: [genuinely empty; no worked answer]
3. Calculate the exact combined batches. Is stock enough, and what is left?
Own response: [genuinely empty; no worked answer]
4. Explain why 58 needs checking. Use a connected inverse check for your own exact total.
Own response: [genuinely empty; no worked answer]
