TOPIC: FRACTIONS OF OBJECTS AND SHAPES
A: TEACHING AND LEARNING MATERIALS
- Fraction chart.
- Paper circles.
- Paper squares and rectangles.
- Fruits such as oranges.
- Coloured pencils.
B: REFERENCE MATERIALS
- Scheme of work.
- Recommended Mathematics textbook for Primary 3.
- Online educational resources.
C: PREVIOUS KNOWLEDGE
The pupils have learnt that objects can be divided into equal parts.
D: PERFORMANCE OBJECTIVES
By the end of the lesson, pupils should be able to:
- Explain the meaning of a fraction.
- Identify ½, ⅓ and ¼.
- Identify ⅕ and ⅙.
- Divide shapes into equal parts.
- Shade given fractions of shapes.
E: CONTENT
Meaning of a Fraction
A fraction is a part of a whole.
If an orange is divided into 2 equal parts, each part is called one-half (½).
🍊 → ½ + ½
Common Fractions
- ½ = one-half
- ⅓ = one-third
- ¼ = one-quarter
- ⅕ = one-fifth
- ⅙ = one-sixth
Fractions of Shapes
If a square is divided into four equal parts and one part is shaded, the shaded part is:
¼
If a circle is divided into two equal parts and one part is coloured, the coloured part is:
½
Equal Parts
The parts of a fraction must be equal.
For example, a cake divided into four equal pieces gives quarters.
🎂 → ¼ + ¼ + ¼ + ¼
