Primary 4 Mathematics Quiz - Measurement (Answer Key)

Total Marks: 40
Topic: Measurement (syllabus-first; no past-paper evidence used)

Section A (1 mark each)

1. 2.45 m
Teaching note: 100 cm = 1 m, so 245 cm ÷ 100 = 2.45 m. Common mistake: writing 245 m.

2. 0.85 kg
Teaching note: 1000 g = 1 kg, so 850 g ÷ 1000 = 0.85 kg.

3. 2300 mL
Teaching note: 1 L = 1000 mL, so 2 L = 2000 mL; 2000 + 300 = 2300 mL.

4. 5 km
Teaching note: 4.78 km → look at tenths digit (7 ≥ 5), round up to 5 km.

5. 28 m
Teaching note: Perimeter = 2 × (length + breadth) = 2 × (8 + 6) = 28 m.

6. 81 cm²
Teaching note: Area of square = side × side = 9 × 9 = 81 cm².

7. 3500 g
Teaching note: 1 kg = 1000 g, so 3.5 × 1000 = 3500 g.

8. 120 cm
Teaching note: 1 m = 100 cm, so 1.2 × 100 = 120 cm.

9. 24000 mL
Teaching note: 1 L = 1000 mL, so 24 × 1000 = 24000 mL.

10. 1.35 m
Teaching note: 135 cm ÷ 100 = 1.35 m.

Section B (2 marks each)

11. Breadth = 7 cm
Working: Perimeter = 2 × (length + breadth) → 38 = 2 × (12 + b) → 19 = 12 + b → b = 7 cm.
Marking: 1 mark for equation, 1 mark for correct answer.

12. Side = 8 cm
Working: Area = side² → side = √64 = 8 cm.
Marking: 1 mark for square root step, 1 mark for answer.

13. 4250 m
Working: 2.45 km = 2450 m; 1.8 km = 1800 m; total = 2450 + 1800 = 4250 m.
Marking: 1 mark for conversion, 1 mark for sum.

14. 3 kg
Working: 750 g × 4 = 3000 g; 3000 g = 3 kg.
Marking: 1 mark for multiplication, 1 mark for conversion.

15. 12250 mL
Working: 15 L 500 mL = 15500 mL; 3 L 250 mL = 3250 mL; left = 15500 − 3250 = 12250 mL.
Marking: 1 mark for conversion, 1 mark for subtraction.

16. 45 cm²
Working: Area A = 4 × 6 = 24 cm²; Area B = 7 × 3 = 21 cm²; total = 24 + 21 = 45 cm².
Image note: Diagram shows two rectangles with given dimensions; no overlap.
Marking: 1 mark per area, total 2 marks.

Section C (3 marks each)

17. $200 *Working:* Perimeter = 2 × (15 + 10) = 50 m; cost = 50 ×$ 4 = $200.
Marking: 1 mark perimeter, 1 mark multiplication, 1 mark answer.

18. 65 cm²
Working: Square side = 36 ÷ 4 = 9 cm; square area = 9 × 9 = 81 cm²; rectangle area = 8 × 4 = 32 cm²; remaining = 81 − 32 = 49 cm².
Correction: 81 − 32 = 49 cm² (not 65). Answer: 49 cm².
Marking: 1 mark square side/area, 1 mark rectangle area, 1 mark subtraction.

19. 10.5 kg
Working: 5 bags × 2 kg = 10 kg; 500 g = 0.5 kg; total = 10 + 0.5 = 10.5 kg.
Marking: 1 mark bags, 1 mark conversion, 1 mark total.

20. 500000 L
Working: Volume = 25 × 10 × 2 = 500 m³; 500 × 1000 = 500000 L.
Marking: 1 mark volume in m³, 1 mark conversion, 1 mark answer.
