Answers
Primary 5 Mathematics Quiz - Measurement
Answer Key
Section A: Multiple Choice Questions (10 marks)
1. C (kilograms)
Marking note: A watermelon typically weighs 2–5 kg. Grams are too small; tonnes are too large.
2. C (3,450)
Working: 3 km = 3 × 1,000 = 3,000 m; 3,000 + 450 = 3,450 m
3. C (5,000 ml)
Working: 1 litre = 1,000 ml; 5 × 1,000 = 5,000 ml
4. C (2,750)
Working: 2 kg = 2 × 1,000 = 2,000 g; 2,000 + 750 = 2,750 g
5. C (2 m)
Marking note: A standard door is approximately 2 m tall. 2 cm and 20 cm are far too short; 20 m is unreasonably tall.
6. C (4,500)
Working: 1 km = 1,000 m; 4.5 × 1,000 = 4,500 m
7. C (1,250 ml)
Working: 1 litre = 1,000 ml; 1.25 × 1,000 = 1,250 ml
8. B (6.8 kg)
Working: 1 kg = 1,000 g; 6,800 ÷ 1,000 = 6.8 kg
9. C (cm)
Marking note: A textbook is typically 1–2 cm thick. 15 mm (1.5 cm) is also reasonable, but cm is the more standard unit at this level. Accept C as the best answer.
10. C (6 litres 250 ml)
Working: 3 litres 400 ml + 2 litres 850 ml = (3 + 2) litres + (400 + 850) ml = 5 litres 1,250 ml = 6 litres 250 ml
Section B: Short Answer Questions (15 marks)
11. (3 marks — 1 mark per part)
(a) 7,000 m
Working: 1 km = 1,000 m; 7 × 1,000 = 7,000 m
(b) 8 litres 500 ml
Working: 8,500 ÷ 1,000 = 8 remainder 500; so 8 litres 500 ml
(c) 4,300 g
Working: 4 kg = 4 × 1,000 = 4,000 g; 4,000 + 300 = 4,300 g
12. 260 cm (3 marks)
Working: 2 m = 2 × 100 = 200 cm; 200 + 60 = 260 cm
Marking note: Award 1 mark for correct conversion of metres to cm, 1 mark for correct addition, 1 mark for final answer with unit.
13. 4 litres 500 ml (3 marks)
Working: 1 litre 500 ml × 3 = (1 × 3) litres + (500 × 3) ml = 3 litres 1,500 ml = 4 litres 500 ml
Marking note: Award 1 mark for multiplication step, 1 mark for converting 1,500 ml to 1 litre 500 ml, 1 mark for final answer.
14. 4,800 m, 520,000 cm, 5 km, 6,000,000 mm (3 marks)
Working: Convert all to metres:
- 5 km = 5,000 m
- 4,800 m = 4,800 m
- 520,000 cm = 520,000 ÷ 100 = 5,200 m
- 6,000,000 mm = 6,000,000 ÷ 1,000 = 6,000 m
Order: 4,800 m < 5 km < 520,000 cm < 6,000,000 mm
Marking note: Award 2 marks for correct conversions, 1 mark for correct order. Accept answers in original units as long as the order is correct.
15. 4 litres 250 ml (3 marks)
Working: 8 litres = 8 litres 0 ml; 8 litres 0 ml − 3 litres 750 ml Borrow 1 litre = 1,000 ml: 7 litres 1,000 ml − 3 litres 750 ml = 4 litres 250 ml
Marking note: Award 1 mark for borrowing/converting, 1 mark for correct subtraction, 1 mark for final answer.
Section C: Structured / Word Problem Questions (15 marks)
16. (3 marks)
(a) 11 litres 150 ml
Working: 4 litres 350 ml + 6 litres 800 ml = (4 + 6) litres + (350 + 800) ml = 10 litres 1,150 ml = 11 litres 150 ml
(b) 3 litres 850 ml
Working: 15 litres − 11 litres 150 ml = 14 litres 1,000 ml − 11 litres 150 ml = 3 litres 850 ml
Marking note: Award 1 mark for part (a), 2 marks for part (b) including working and final answer. If part (b) uses wrong answer from (a) but method is correct, award 1 mark (error carried forward).
17. 80 cm (3 marks)
Working: 4 m = 4 × 100 = 400 cm; 400 ÷ 5 = 80 cm
Marking note: Award 1 mark for converting m to cm, 1 mark for division, 1 mark for final answer with unit.
18. (3 marks)
(a) 25 kg 750 g
Working: 38 kg 500 g − 12 kg 750 g = 37 kg 1,500 g − 12 kg 750 g = 25 kg 750 g
(b) 64 kg 250 g
Working: 38 kg 500 g + 25 kg 750 g = 63 kg 1,250 g = 64 kg 250 g
Marking note: Award 2 marks for part (a), 1 mark for part (b). Award error carried forward for part (b) if part (a) is wrong but method is correct.
19. (3 marks)
(a) 8 litres 150 ml
Working: 2 litres 400 ml + 3 litres 800 ml + 1 litre 950 ml = (2 + 3 + 1) litres + (400 + 800 + 950) ml = 6 litres 2,150 ml = 8 litres 150 ml
(b) 1 litre 850 ml
Working: 10 litres − 8 litres 150 ml = 9 litres 1,000 ml − 8 litres 150 ml = 1 litre 850 ml
Marking note: Award 2 marks for part (a), 1 mark for part (b). Error carried forward accepted.
20. (3 marks)
(a) 7,500 kg
Working: 2 tonnes 500 kg = 2,000 + 500 = 2,500 kg; 2,500 × 3 = 7,500 kg
(b) 6,300 kg
Working: 7,500 − 1,200 = 6,300 kg
Marking note: Award 2 marks for part (a) including conversion and multiplication, 1 mark for part (b). Error carried forward accepted.
