Answers
Primary 3 Mathematics Quiz - Measurement (Answer Key)
Total Marks: 40
Topic: Measurement (Length, Mass, Volume conversions and compound units)
Section A Answers (1 mark each)
1. 3000 m
Teaching note: 1 km = 1000 m, so 3 km = 3 × 1000 = 3000 m.
2. 2 km 500 m
Teaching note: 2500 m = 2000 m + 500 m = 2 km 500 m.
3. 4000 g
Teaching note: 1 kg = 1000 g, so 4 kg = 4 × 1000 = 4000 g.
4. 3 kg 500 g
Teaching note: 3500 g = 3000 g + 500 g = 3 kg 500 g.
5. 2000 mL
Teaching note: 1 L = 1000 mL, so 2 L = 2 × 1000 = 2000 mL.
6. 4 L 500 mL
Teaching note: 4500 mL = 4000 mL + 500 mL = 4 L 500 mL.
7. 700 cm
Teaching note: 1 m = 100 cm, so 7 m = 7 × 100 = 700 cm.
8. 8 m 20 cm
Teaching note: 820 cm = 800 cm + 20 cm = 8 m 20 cm.
9. 5300 m
Teaching note: 5 km = 5000 m, plus 300 m = 5300 m.
10. 6250 g
Teaching note: 6 kg = 6000 g, plus 250 g = 6250 g.
Section B Answers (2 marks each)
11. 240 cm
Working: 2 m = 200 cm, plus 40 cm = 240 cm.
Marking: 1 mark for converting 2 m to 200 cm, 1 mark for total 240 cm.
12. 1500 mL
Working: 1 L = 1000 mL, plus 500 mL = 1500 mL.
Marking: 1 mark conversion, 1 mark final.
13. Boy is farther by 270 m
Working: Boy: 1 km 250 m = 1250 m. Friend: 980 m. 1250 > 980, difference = 1250 − 980 = 270 m.
Marking: 1 mark identify boy, 1 mark difference.
14. 5850 g
Working: 2 kg 750 g = 2750 g; 3 kg 100 g = 3100 g. Total = 2750 + 3100 = 5850 g.
Marking: 1 mark each conversion/addition.
15. 2600 mL
Working: 4 L 200 mL = 4200 mL; 1 L 600 mL = 1600 mL. Left = 4200 − 1600 = 2600 mL.
Marking: 1 mark conversion, 1 mark subtraction.
16. 250 cm
Working: 5 m = 500 cm. Each piece = 500 ÷ 2 = 250 cm.
Marking: 1 mark convert to cm, 1 mark divide.
Section C Answers (3 marks each)
17.
(a) 5 km 700 m
(b) 5700 m
Working: Mon: 2 km 500 m, Tue: 3 km 200 m. Total km: 2+3=5 km. Total m: 500+200=700 m. So 5 km 700 m = 5700 m.
Marking: 1 mark add km, 1 mark add m, 1 mark convert to m.
18.
(a) 8 kg 200 g
(b) 8200 g
Working: Morning 5 kg 400 g, afternoon 2 kg 800 g. kg: 5+2=7 kg; g: 400+800=1200 g = 1 kg 200 g. Total = 8 kg 200 g = 8200 g.
Marking: 1 mark add, 1 mark carry, 1 mark convert.
19.
(a) 650 mL
(b) 0 L 650 mL (or 650 mL)
Working: 3 L 250 mL = 3250 mL. 3250 ÷ 5 = 650 mL per cup.
Marking: 1 mark convert, 1 mark divide, 1 mark express.
20.
(a) 2 m 80 cm
(b) 280 cm
Working: 4 m 60 cm − 1 m 80 cm. Borrow 1 m = 100 cm: 3 m 160 cm − 1 m 80 cm = 2 m 80 cm = 280 cm.
Marking: 1 mark borrow, 1 mark subtract, 1 mark convert.
Common mistake: Forgetting to borrow when cm subtract needs it.
