03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 25 | 12 minus 7 is 5, and 4 minus 2 is 2, so the answer is 25. |
| 2 | 25 | 13 minus 8 is 5, and 3 minus 1 is 2, so the answer is 25. |
| 3 | 26 | 11 minus 5 is 6, and 5 minus 3 is 2, so the answer is 26. |
| 4 | 36 | Borrow one ten so 14 minus 8 is 6, then 6 minus 3 is 3. |
| 5 | 44 | The 0 borrows a ten, so 10 minus 6 is 4, then 8 minus 4 is 4. |
| 6 | 28 | 15 minus 7 is 8, and 7 minus 5 is 2, so the answer is 28. |
| 7 | 34 | 13 minus 9 is 4, and 5 minus 2 is 3 because one ten was borrowed. |
| 8 | $22 | 50 minus 28: 10 minus 8 is 2, and 4 minus 2 is 2, so the change is $22. |
| 9 | 47 sweets | 72 minus 25: 12 minus 5 is 7, and 6 minus 2 is 4, so 47 sweets remain. |
| 10 | He forgot to reduce the tens by one; the correct answer is 27 | 13 minus 6 is 7, and after borrowing the tens go 5 to 4, so 4 minus 2 gives 2. |
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.
