03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 85. | Ones: 7 + 8 = 15, write 5 and carry 1; tens: 5 + 2 + 1 = 8. |
| 2 | 84. | Ones: 8 + 6 = 14, write 4 and carry 1; tens: 4 + 3 + 1 = 8. |
| 3 | 86. | Ones: 9 + 7 = 16, write 6 and carry 1; tens: 6 + 1 + 1 = 8. |
| 4 | 132. | Ones: 8 + 4 = 12, write 2 carry 1; tens: 7 + 5 + 1 = 13, so a further carry makes three digits. |
| 5 | $92. | 63 + 29: ones give 12 so carry 1, then tens 6 + 2 + 1 = 9, giving $92. |
| 6 | 48. | Work backwards: 85 – 37 needs borrowing in the ones column and gives 48, and 48 + 37 is 85 again. |
| 7 | 113. | First 56 + 38 = 94, then 94 + 19 = 113; both steps carry from the ones column. |
| 8 | Yes, both are 82. | Taking 1 from one addend and adding it to the other keeps the total, so both give 82. |
| 9 | 91 and 107. | 64 + 27 = 91, then + 16 = 107; the second carry also goes to the tens column. |
| 10 | 82. | Ones: 5 + 7 = 12, write 2 and carry 1; tens: 4 + 3 + 1 = 8, so the answer is 82. The slip was a dropped carry. |
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.
