Primary 4 Mathematics Quiz - Measurement (Answer Key)

Total Marks: 40

Section A: Multiple-Choice Questions (10 × 1 mark = 10 marks)

1. Answer: (3) metres
Explanation: A classroom is typically several metres long. Millimetres and centimetres are too small for measuring room dimensions, while kilometres are used for much longer distances like between towns.

2. Answer: (2) 3045 m
Explanation: 3 km = 3 × 1000 m = 3000 m. 3000 m + 45 m = 3045 m.
Common mistake: Forgetting that 1 km = 1000 m, not 100 m.

3. Answer: (2) 2050 g
Explanation: 2 kg = 2 × 1000 g = 2000 g. 2000 g + 50 g = 2050 g.
Common mistake: Thinking 2 kg 50 g = 250 g (treating kg and g as same unit) or 2500 g (thinking 50 g = 500 g).

4. Answer: (3) 1250 mℓ
Explanation: 1 ℓ = 1000 mℓ. 1000 mℓ + 250 mℓ = 1250 mℓ.

5. Answer: (2) 1 h 25 min
Explanation: From 4:20 p.m. to 5:20 p.m. = 1 hour. From 5:20 p.m. to 5:45 p.m. = 25 minutes. Total = 1 h 25 min.
Alternative method: 5:45 − 4:20 = 1:25 (since 45 − 20 = 25 minutes, 5 − 4 = 1 hour).

6. Answer: (4) 24000 cm³
Explanation: Volume = length × breadth × height = 40 × 30 × 20 = 24000 cm³.
Common mistake: Adding instead of multiplying, or calculating surface area.

7. Answer: (2) 1 ℓ 750 mℓ
Explanation: 3 ℓ 500 mℓ − 1 ℓ 750 mℓ. Convert to mℓ: 3500 mℓ − 1750 mℓ = 1750 mℓ = 1 ℓ 750 mℓ.
Alternative: Borrow 1 ℓ = 1000 mℓ: 2 ℓ 1500 mℓ − 1 ℓ 750 mℓ = 1 ℓ 750 mℓ.

8. Answer: (3) 6 kg 150 g
Explanation: 4 kg 300 g + 1 kg 850 g = 5 kg 1150 g = 5 kg + 1 kg 150 g = 6 kg 150 g.
Key step: 1150 g = 1000 g + 150 g = 1 kg 150 g.

9. Answer: (2) 2 h 35 min
Explanation: From 09 15 to 11 15 = 2 hours. From 11 15 to 11 50 = 35 minutes. Total = 2 h 35 min.
Alternative: 11 50 − 09 15 = 2 h 35 min (50 − 15 = 35 min, 11 − 9 = 2 h).

10. Answer: (4) 512 cm³
Explanation: Volume of cube = side × side × side = 8 × 8 × 8 = 512 cm³.
Common mistake: Calculating 8 × 3 = 24 (perimeter of one face) or 8 × 8 = 64 (area of one face).

Section B: Short-Answer Questions (10 × 2 marks = 20 marks)

11. Answer: 5080 m
Working:
5 km = 5 × 1000 m = 5000 m
5000 m + 80 m = 5080 m
Marks: 1 mark for correct conversion (5 km = 5000 m), 1 mark for correct final answer.

12. Answer: 47 cm
Working:
2 m 35 cm = 200 cm + 35 cm = 235 cm
235 cm ÷ 5 = 47 cm
Marks: 1 mark for converting to cm (235 cm), 1 mark for correct division and answer.

13. Answer: 5 kg 600 g
Working:
6 kg 400 g − 800 g
= 6 kg 400 g − 0 kg 800 g
Borrow 1 kg = 1000 g: 5 kg 1400 g − 0 kg 800 g = 5 kg 600 g
Marks: 1 mark for correct borrowing/conversion, 1 mark for correct final answer in kg and g.

14. Answer: 1 ℓ 650 mℓ
Working:
4 ℓ − 2 ℓ 350 mℓ
= 4000 mℓ − 2350 mℓ = 1650 mℓ
= 1 ℓ 650 mℓ
Alternative: Borrow 1 ℓ = 1000 mℓ: 3 ℓ 1000 mℓ − 2 ℓ 350 mℓ = 1 ℓ 650 mℓ
Marks: 1 mark for correct subtraction method, 1 mark for correct final answer in ℓ and mℓ.

15. Answer: 2 h 25 min
Working:
From 7:15 p.m. to 9:15 p.m. = 2 hours
From 9:15 p.m. to 9:40 p.m. = 25 minutes
Total = 2 h 25 min
Marks: 1 mark for correct hour calculation, 1 mark for correct minute calculation and final answer.

16. Answer: 40000 cm³
Working:
Volume of water = length × breadth × water height
= 50 cm × 40 cm × 20 cm
= 2000 cm² × 20 cm
= 40000 cm³
Note: Use water height (20 cm), not tank height (30 cm).
Marks: 1 mark for using correct dimensions (50 × 40 × 20), 1 mark for correct calculation and unit.

17. Answer: 1 h 30 min
Working:
First journey: 07 30 to 08 15 = 45 min
Second journey: 09 00 to 09 45 = 45 min
Total = 45 min + 45 min = 90 min = 1 h 30 min
Marks: 1 mark for each correct journey duration, 1 mark for correct total in h and min. (Award 2 marks if final answer correct with clear working.)

18. Answer: 1187.5 mℓ (or 1187 mℓ if rounding to whole number)
Working:
8 ℓ 500 mℓ = 8500 mℓ
3 ℓ 750 mℓ = 3750 mℓ
Remaining = 8500 − 3750 = 4750 mℓ
Each bottle = 4750 ÷ 4 = 1187.5 mℓ
Note: At Primary 4, students may give answer as 1187.5 mℓ or 1 ℓ 187.5 mℓ. Accept 1188 mℓ if rounded.
Marks: 1 mark for correct conversion and subtraction, 1 mark for correct division and answer in mℓ.

19. Answer: 7 kg 800 g
Working:
Mass of durian = 2 kg 600 g = 2600 g
Mass of jackfruit = 2600 g × 3 = 7800 g
7800 g = 7000 g + 800 g = 7 kg 800 g
Alternative: 2 kg 600 g × 3 = 6 kg 1800 g = 6 kg + 1 kg 800 g = 7 kg 800 g
Marks: 1 mark for correct multiplication method, 1 mark for correct final answer in kg and g.

20. Answer: 9000 cm³
Working:
Volume = base area × height
= 600 cm² × 15 cm
= 9000 cm³
Marks: 1 mark for correct formula (base area × height), 1 mark for correct calculation and unit.

Marking Notes for Teachers

  • Unit conversion: Always check that students convert to the same unit before adding/subtracting.
  • Regrouping: For subtraction involving mixed units (e.g., kg and g, ℓ and mℓ), students must show borrowing/regrouping clearly.
  • Time calculation: Encourage timeline or "counting up" method for time duration questions.
  • Volume: Distinguish between volume of container (full capacity) and volume of water (using water height).
  • Decimal answers: For Q18, accept 1187.5 mℓ or 1 ℓ 187.5 mℓ. If student writes 1188 mℓ (rounded), accept with note.
  • Working marks: Award method marks even if final answer has calculation error, provided the method is correct and clearly shown.
