Primary 3 Mathematics - Whole Numbers Quiz 01 - Answer Key
Section A: Multiple Choice Questions (1 mark each)
1. C) 500
The digit 5 is in the hundreds place, so its value is 500.
2. D) 3,564
Comparing the hundreds place: 5 > 4, so 3,564 and 3,546 are larger. Comparing tens: 6 > 4, so 3,564 is the largest.
3. A) 2,800
The tens digit is 4, which is less than 5, so we round down to 2,800.
4. B) 6,672
5,672 + 1,000 = 6,672
5. B) 4,125, 4,251, 4,512, 4,521
Ascending order means from smallest to largest.
Section B: Short Answer Questions (2 marks each)
6. 6,342
Six thousand = 6,000, three hundred = 300, forty-two = 42. Total = 6,342
7. 7,842, 7,824, 7,428, 7,284
Descending order means from largest to smallest.
8. 3,030
The first 3 is in the thousands place (value = 3,000). The second 3 is in the tens place (value = 30). Sum = 3,000 + 30 = 3,030
9. 4,208
4 thousands + 2 hundreds + 0 tens + 8 ones = 4,000 + 200 + 0 + 8 = 4,208
10. 6,560
The ones digit is 5, so we round up to 6,560.
Section C: Problem Solving (2 marks each)
11. 3,800 beads
2,458 rounded to nearest hundred = 2,500
1,326 rounded to nearest hundred = 1,300
Estimated total = 2,500 + 1,300 = 3,800
12. Five thousand, eight hundred and ninety-two
5,892 = 5 thousands + 8 hundreds + 9 tens + 2 ones
13. 7,070 (Accept any valid answer like 7,071, 7,072, 7,073, 7,074, 7,075, 7,076, 7,078, 7,079, 7,170, 7,270, 7,370, 7,470, 7,570, 7,670, 7,870, 7,970)
The number must have 7 in the thousands place and 7 in the tens place.
14. 3,900
4,000 - 100 = 3,900
15. 3,850, 4,050
The pattern increases by 200 each time. 3,650 + 200 = 3,850, 3,850 + 200 = 4,050
