03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 1 ten and 4 ones | The tens digit of 14 is 1 and the ones digit is 4, so 14 is 1 ten and 4 ones. |
| 2 | 13 | 8 plus 2 makes 10, then add 3 more to get 13. |
| 3 | 8 | Take 7 away from 17 to reach 10, then take 2 more to get 8. |
| 4 | 2 | Only 13 and 14 sit between 12 and 15, so there are 2. |
| 5 | 19 | The odd numbers are 1, 3, 5 … 19, and 19 is the largest under 20. |
| 6 | 12 | 3 plus 4 is 7, and 7 plus 5 is 12. |
| 7 | 5 | A difference is found by subtracting: 18 – 13 = 5. |
| 8 | 16 | 9 comes before 16 on the number line, so 16 is greater. |
| 9 | 17 | Altogether means addition: 10 + 7 = 17. |
| 10 | 12 | 20 – 8 = 12; 14 comes from subtracting 6 instead of 8. |
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.
