03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | $23 | $14 + $9 = $23, so the total is $23. |
| 2 | $29 | $48 − $19 = $29, so the new price is $29. |
| 3 | $24 | $6 × 4 = $24, so 4 buns cost $24. |
| 4 | $32 | $100 − $68 = $32, so the change is $32. |
| 5 | $20 | $7.50 + $12.50 = $20, so the total is $20. |
| 6 | $31.5 | $50 − $18.50 = $31.50, so the change is $31.50. |
| 7 | $24 | $5 × 4 = $20 and $2 × 2 = $4, so $20 + $4 = $24. |
| 8 | $10 | $3.60 + $4.40 = $8 and $8 + $2 = $10, so the total is $10. |
| 9 | $0.63 | $2.70 − $2.07 = $0.63, so the difference is $0.63. |
| 10 | $14 | $100 − $86 = $14: borrow one ten from the hundreds, so not $24. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
