03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 4. | The small brackets give 6, the square brackets give 30, and 120 / 30 = 4. |
| 2 | 50. | The brackets give 20 and 4, so 20 x 4 = 80 and 80 – 30 = 50. |
| 3 | 6. | The brackets give 12, then 3 x 12 = 36 and 36 / 6 = 6. |
| 4 | 80. | The brackets give 60, then 60 x 2 = 120 and 200 – 120 = 80. |
| 5 | 3. | Inside the square brackets 4 x 3 = 12 and 12 + 6 = 18; the divisor is 6; 18 / 6 = 3. |
| 6 | 22 dollars. | Four pens cost 7 x 4 = 28 dollars, so the change is 50 – 28 = 22 dollars. |
| 7 | 15. | The brackets give 8, then 240 / 8 = 30 and 30 – 15 = 15. |
| 8 | 41. | The brackets give 6, then 36; the division gives 5; 36 + 5 = 41. |
| 9 | 7. | The brackets give 42 and 6, and 42 / 6 = 7. |
| 10 | It should be 4. | The pupil did 24 / 4 first and then added 2; the bracket gives 6 and 24 / 6 = 4. |
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.
Check the answers; for a wrong item, circle the brackets and rewrite the steps in order.Tutor Registration →
