Answers

Primary 2 Mathematics Quiz - Length (Answer Key)

Total Marks: 20
Topic: Length (syllabus-first, not past-year derived)

Q1. m
Marks: 1
Teaching note: The short form for metres is "m". We use metres to measure longer things like a classroom.
Common mistake: Writing "metres" instead of "m" – the question asks for short form.

Q2. 1.5 m
Marks: 1
Teaching note: From the ruler image, the line starts at 0 and ends at the 1.5 m mark. So length = 1.5 m.
Image check: Ruler must show 0, 0.5, 1.0, 1.5, 2.0; line ends at 1.5 m.

Q3. 3 m
Marks: 1
Teaching note: 3 m = 300 cm. 300 cm is more than 80 cm, so 3 m is longer.
Method: Convert to same unit (cm) to compare: 3 m = 300 cm > 80 cm.

Q4. 2.5 m
Marks: 1
Teaching note: 100 cm = 1 m, so 250 cm = 200 cm + 50 cm = 2 m 50 cm = 2.5 m.

Q5. 400 cm
Marks: 1
Teaching note: 1 m = 100 cm, so 4 m = 4 × 100 = 400 cm.

Q6. 90 cm, 150 cm, 2 m, 3 m
Marks: 1
Teaching note: Convert all to cm: 90 cm, 150 cm, 200 cm (2 m), 300 cm (3 m). Order: 90 < 150 < 200 < 300.

Q7. Ruler: 30 cm ✓
Marks: 1
Teaching note: Compare: 15 cm < 25 cm < 30 cm. Ruler is longest.

Q8. 1 m ribbon
Marks: 1
Teaching note: 1 m = 100 cm. 100 cm < 120 cm, so 1 m ribbon is shorter.

Q9. >
Marks: 1
Teaching note: 2 m = 200 cm. 200 cm > 180 cm, so use ">".

Q10. Ahmad
Marks: 1
Teaching note: 1 m = 100 cm. 100 cm > 95 cm, so Ahmad jumped farther.

Q11. 3 m
Marks: 1
Teaching note: 2 m + 1 m = 3 m. Add lengths in same unit.

Q12. 3 m
Marks: 1
Teaching note: 5 m − 2 m = 3 m. Subtract the cut part.

Q13. Bookshelf 1 (3 m) is wider
Marks: 2 (1 for converting 250 cm to 2.5 m, 1 for correct comparison)
Working: 250 cm = 2.5 m. 3 m > 2.5 m.
Teaching note: Always convert to same unit before comparing.

Q14. 120 cm
Marks: 2 (1 for converting 2 m to 200 cm, 1 for subtraction)
Working: 2 m = 200 cm. 200 − 80 = 120 cm.

Q15. 95 cm
Marks: 2 (1 for each day's addition or 1 for setup, 1 for total)
Working: 40 + 55 = 95 cm.

Q16. 5 m
Marks: 2 (1 for identifying subtraction, 1 for answer)
Working: 8 m − 3 m = 5 m.

Q17. Student draws a line labelled Start and End representing 2 m
Marks: 1
Teaching note: Accept any clear line in the box with Start and End marked; concept is showing 2 m length.

Q18. 150 cm
Marks: 2 (1 for 1 m = 100 cm, 1 for adding 50)
Working: 1 m = 100 cm, 100 + 50 = 150 cm.

Q19. 2 m 70 cm (or 270 cm)
Marks: 2 (1 for adding 120+150, 1 for unit answer)
Working: 120 cm + 150 cm = 270 cm = 2 m 70 cm.

Q20. 3 m
Marks: 2 (1 for total cm, 1 for converting to m)
Working: 4 × 75 cm = 300 cm. 300 cm = 3 m.
