Show answers and working
1. 1/4 shaded, 3/4 not shaded
Denominator = total equal parts = 4. Numerator = shaded parts = 1. Unshaded: 4 − 1 = 3, so 3/4.
2. 4/8 shaded, 4/8 not shaded
Denominator = total equal parts = 8. Numerator = shaded parts = 4. Unshaded: 8 − 4 = 4, so 4/8.
3. 5/6 shaded, 1/6 not shaded
Denominator = total equal parts = 6. Numerator = shaded parts = 5. Unshaded: 6 − 5 = 1, so 1/6.
4. 1/5 shaded, 4/5 not shaded
Denominator = total equal parts = 5. Numerator = shaded parts = 1. Unshaded: 5 − 1 = 4, so 4/5.
5. 7/9 shaded, 2/9 not shaded
Denominator = total equal parts = 9. Numerator = shaded parts = 7. Unshaded: 9 − 7 = 2, so 2/9.
6. 1/3 shaded, 2/3 not shaded
Denominator = total equal parts = 3. Numerator = shaded parts = 1. Unshaded: 3 − 1 = 2, so 2/3.
7. 5/9 shaded, 4/9 not shaded
Denominator = total equal parts = 9. Numerator = shaded parts = 5. Unshaded: 9 − 5 = 4, so 4/9.
8. 4/12 shaded, 8/12 not shaded
Denominator = total equal parts = 12. Numerator = shaded parts = 4. Unshaded: 12 − 4 = 8, so 8/12.
9. 2/3 shaded, 1/3 not shaded
Denominator = total equal parts = 3. Numerator = shaded parts = 2. Unshaded: 3 − 2 = 1, so 1/3.
10. 8/14 shaded, 6/14 not shaded
Denominator = total equal parts = 14. Numerator = shaded parts = 8. Unshaded: 14 − 8 = 6, so 6/14.
11. 9/11 shaded, 2/11 not shaded
Denominator = total equal parts = 11. Numerator = shaded parts = 9. Unshaded: 11 − 9 = 2, so 2/11.
12. 1/2 shaded, 1/2 not shaded
Denominator = total equal parts = 2. Numerator = shaded parts = 1. Unshaded: 2 − 1 = 1, so 1/2.

Common mistakes
What learners typically get wrong, and how to fix it.
Counts unequal parts as fractions.
Correction: Parts must be the same size.
Swaps numerator and denominator.
Correction: The denominator is down — it is the total number of parts.
Teacher tips
- · Fold paper strips into equal parts and label them.
Parent tips
- · Ask what fraction of the family is wearing blue.
Real-life applications
- · Sharing food fairly, telling the time (quarter past).
