Section A: Multiple Choice (12 marks)
| Q | Answer | Explanation |
|---|---|---|
| 1 | C) 1/4 | 1 part shaded out of 4 equal parts = 1/4 |
| 2 | A) 1/2 | 1/2 > 1/4 (fewer parts = bigger pieces) |
| 3 | B) 3/5 | 2/5 + 1/5 = 3/5 (add numerators, keep denominator) |
| 4 | A) 1/2 or D) 3/6 | 3 out of 6 = 3/6 = 1/2 (both acceptable) |
| 5 | B) 1/6 | 1/6 < 1/3 (more parts = smaller pieces) |
| 6 | B) 3/8 | 5/8 - 2/8 = 3/8 |
| 7 | C) 4 | 4 quarters = 1 whole (4/4 = 1) |
| 8 | B) 4 equal parts | Denominator tells how many equal parts the whole is divided into |
| 9 | B) 1/4, 1/3, 1/2 | More parts = smaller fraction: 1/4 < 1/3 < 1/2 |
| 10 | C) 5/6 | 1/6 + 4/6 = 5/6 |
| 11 | A) 1/3 | 1 part not shaded out of 3 = 1/3 |
| 12 | C) 3/7 | 4/7 - 1/7 = 3/7 |
Section B: Short Answer (13 marks)
13. (2 marks)
⬛⬛⬜⬜ (2 out of 4 parts shaded)
Award 2 marks for shading exactly 2 parts
14. (3 marks)
a) 3/5 < 4/5 (same denominator, compare numerators: 3 < 4)
b) 1/2 = 2/4 (1/2 is equivalent to 2/4)
c) 2/6 < 4/6 (same denominator, compare numerators: 2 < 4)
1 mark per correct comparison
15. (2 marks)
Working: 2/8 + 3/8 = 5/8
Answer: 5/8
16. (3 marks)

Teacher's Notes
Key Concepts:
- Numerator = number of parts we have
- Denominator = total number of equal parts
- Same denominator: add/subtract numerators only
- Unit fractions: 1/2 > 1/3 > 1/4 > 1/5 (more parts = smaller pieces)
Common Errors:
- Q3, Q6: Adding denominators (wrong!)
- Q9: Thinking 1/4 is bigger because 4 > 2 (opposite is true for unit fractions)
- Q14b: Not recognizing equivalent fractions
P2 Fraction Limits:
- Denominators up to 12
- Same denominator only for addition/subtraction
- Focus on understanding, not procedures
