03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 100 cm | One metre is always 100 centimetres. |
| 2 | 300 cm | Each metre is 100 cm, so 3 metres is three hundreds. |
| 3 | 2 m 50 cm | 250 divided by 100 gives 2 metres with 50 cm left over. |
| 4 | Centimetres | A pencil is only about ten-odd centimetres long. |
| 5 | Metres | A blackboard is several metres long, so metres read more simply. |
| 6 | 75 cm | The units match, so just add 45 and 30. |
| 7 | 120 cm | Change 1 metre into 100 cm first, then add 20 cm. |
| 8 | 1 m 40 cm | 140 divided by 100 gives 1 metre with 40 cm left over. |
| 9 | 40 cm | Convert both to centimetres: 500 minus 460 is 40. |
| 10 | 100 cm | The factor between metres and centimetres is 100, not 10. |
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.
