03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | Largest 730, smallest 307 | A 0 cannot lead, so the smallest is 307 and not 037. |
| 2 | 582 (18 away) | Checking the arrangements: 582 is 18 away and 528 is 72 away, so 582 wins. |
| 3 | 33 pages | 128 minus 95 is 33; subtract the pages read from the total. |
| 4 | 800 | First 250 plus 360 is 610, then add 190 to reach 800. |
| 5 | 2 steps (850 to 825 to 800) | 850 minus 800 is 50, and 50 divided by 25 is 2. |
| 6 | About 700 | 400 plus 300 is 700; the exact answer is 695, very close. |
| 7 | 10 numbers (50 to 59) | Counting 50 to 59 gives 10 numbers, each with 5 in the tens place. |
| 8 | 46 tens | 460 divided by 10 is 46; every ten ones make one ten. |
| 9 | 443 | 268 plus 175 is 443; the larger number is the smaller plus the gap. |
| 10 | Four digits | 1,000 has thousands, hundreds, tens and ones, four places; digits are not counted by zeros. |
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.
For estimation items, write the rounded values first, then the estimate.Tutor Registration →
