Teacher's Notes
Common Errors to Watch:
- Q4: Starting from 1 instead of 0 when measuring
- Q6, Q10: Adding instead of subtracting for "how much longer/shorter"
- Q7: Confusing shortest to longest with longest to shortest
Partial Marks:
- Q12, Q14: Award 1 mark if calculation is correct but unit missing
- Q13: Award 1 mark if order is correct but reversed
- Q15: Award 1 mark per reasonable estimate
Practical Activity: Before the quiz, have students practice measuring real objects:
- Their erasers (about 4-6 cm)
- Their palms (about 6-8 cm)
- Their books (about 24 cm)
Key Concepts:
- cm = centimetre (for small lengths)
- Start from 0 when measuring
- "Longer" = bigger number, "Shorter" = smaller number
