Primary 4 Mathematics Quiz - Measurement (Answer Key)
Total Marks: 40
Section A: Multiple-Choice Questions (10 × 1 mark = 10 marks)
1. Answer: (C)
Explanation: The length of a classroom is typically a few metres. Millimetres and centimetres are too small (used for small objects like pencils or books). Kilometres are too large (used for distances between places). Metres are the appropriate unit for room dimensions.
2. Answer: (B)
Working:
3 km = 3 × 1000 m = 3000 m
3 km 45 m = 3000 m + 45 m = 3045 m
Key concept: 1 km = 1000 m. Convert km to m first, then add the remaining metres.
3. Answer: (C)
Working:
5 kg = 5 × 1000 g = 5000 g
5 kg 200 g = 5000 g + 200 g = 5200 g
Key concept: 1 kg = 1000 g. Convert kg to g first, then add the remaining grams.
4. Answer: (C)
Working:
1.5 ℓ = 1.5 × 1000 mℓ = 1500 mℓ
Key concept: 1 ℓ = 1000 mℓ. Multiply the number of litres by 1000 to get millilitres.
5. Answer: (B)
Working:
John's height = 1.35 m = 1 m 35 cm
Mary is 15 cm taller: 1 m 35 cm + 15 cm = 1 m 50 cm = 1.50 m
Common mistake: Adding 15 to 1.35 directly (1.35 + 15 = 16.35) without converting units. Always ensure same units before adding/subtracting.
6. Answer: (B)
Working:
Volume of water = Length × Breadth × Height of water
= 40 cm × 30 cm × 15 cm
= 18 000 cm³
Key concept: Volume of cuboid = L × B × H. Use the height of the water (15 cm), not the full tank height (20 cm).
7. Answer: (B)
Working:
600 g = 600 ÷ 1000 kg = 0.6 kg
Total mass = 2.4 kg + 0.6 kg = 3.0 kg
Key concept: Convert grams to kilograms by dividing by 1000 before adding to kilograms.
8. Answer: (B)
Working:
3 m = 300 cm
Length of each piece = 300 cm ÷ 5 = 60 cm
Key concept: Convert to the required unit (cm) first, then divide.
9. Answer: (A)
Working:
Container A = 2 ℓ 500 mℓ = 2500 mℓ
Container B = 1 ℓ 750 mℓ = 1750 mℓ
Difference = 2500 mℓ - 1750 mℓ = 750 mℓ
Alternative: Subtract directly: 2 ℓ 500 mℓ - 1 ℓ 750 mℓ = 0 ℓ 750 mℓ = 750 mℓ
10. Answer: (C)
Working:
Volume of cube = side × side × side
= 6 cm × 6 cm × 6 cm
= 216 cm³
Key concept: All sides of a cube are equal. Volume = side³.
Section B: Short Answer Questions (10 × 2 marks = 20 marks)
11. Answer: 4085 m [2]
Working:
4 km = 4 × 1000 m = 4000 m
4 km 85 m = 4000 m + 85 m = 4085 m
Marking: 1 mark for correct conversion of 4 km to 4000 m, 1 mark for correct final answer.
12. Answer: 7 kg 350 g [2]
Working:
7350 g = 7000 g + 350 g = 7 kg 350 g
Marking: 1 mark for correct kg (7 kg), 1 mark for correct g (350 g).
Note: 1 kg = 1000 g, so divide by 1000: 7350 ÷ 1000 = 7 remainder 350.
13. Answer: 32 cups [2]
Working:
8 ℓ = 8 × 1000 mℓ = 8000 mℓ
Number of cups = 8000 mℓ ÷ 250 mℓ = 32
Marking: 1 mark for converting 8 ℓ to 8000 mℓ, 1 mark for correct division and answer.
14. Answer: 5 kg 250 g [2]
Working:
Watermelon: 3 kg 400 g
Papaya: 1 kg 850 g
Total: 4 kg 1250 g = 4 kg + 1 kg 250 g = 5 kg 250 g
Marking: 1 mark for correct addition (4 kg 1250 g), 1 mark for correct regrouping to 5 kg 250 g.
Common mistake: Writing 4 kg 1250 g without regrouping (1250 g = 1 kg 250 g).
15. Answer: 2 m 65 cm [2]
Working:
5 m = 4 m 100 cm
4 m 100 cm - 2 m 35 cm = 2 m 65 cm
Marking: 1 mark for correct regrouping (5 m = 4 m 100 cm), 1 mark for correct subtraction and answer.
16. Answer: 1200 cm³ [2]
Working:
Volume = Base Area × Height
= 120 cm² × 10 cm
= 1200 cm³
Marking: 1 mark for correct formula/method, 1 mark for correct answer with unit.
17. Answer: 2 kg 550 g [2]
Working:
Total used = 1 kg 600 g + 850 g = 2 kg 450 g
Flour left = 5 kg - 2 kg 450 g
= 4 kg 1000 g - 2 kg 450 g
= 2 kg 550 g
Marking: 1 mark for correct total used (2 kg 450 g), 1 mark for correct subtraction with regrouping and final answer.
18. Answer: 40 000 cm³ [2]
Working:
Volume of tank = 50 cm × 40 cm × 30 cm = 60 000 cm³
Volume of water = ⅔ × 60 000 cm³ = 40 000 cm³
Marking: 1 mark for correct full tank volume (60 000 cm³), 1 mark for correct fraction calculation and answer.
19. Answer: 700 g [2]
Working:
Total mass = 3 kg 200 g = 3200 g
Mass of bag = 400 g
Mass of 4 books = 3200 g - 400 g = 2800 g
Mass of 1 book = 2800 g ÷ 4 = 700 g
Marking: 1 mark for finding mass of 4 books (2800 g), 1 mark for dividing by 4 to get 700 g.
20. Answer: 250 mℓ [2]
Working:
2 ℓ = 2 × 1000 mℓ = 2000 mℓ
Syrup per cup = 2000 mℓ ÷ 8 = 250 mℓ
Marking: 1 mark for converting 2 ℓ to 2000 mℓ, 1 mark for correct division and answer.
Total: 40 marks
