Learning Objectives
By the end of the lesson, students should be able to:
Identify parts of a whole and its shaded parts
Identify and count the divided parts
Name each fractional part
Previous Knowledge
Students already know how to divide objects into equal parts when sharing.
Instructional Materials
Mathematics textbook for Grade 3
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Teacher asks students: “If I cut one apple into two equal parts and give you one, what part of the apple do you have?” Teacher shows objects like fruits, bread, and paper and divides them into equal parts. Students discuss their observations.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
A fraction is a way of showing a part of a whole. For example, if a circle is divided into 2 equal parts and 1 part is shaded, then the shaded part is written as ½. In a fraction, the number on top is called the numerator. It tells us how many parts are shaded or taken. The number at the bottom is the denominator. It tells us how many equal parts the whole is divided into. Examples:
Circle divided into 2 equal parts, 1 shaded = ½
Rectangle divided into 3 equal parts, 2 shaded = ⅔
Square divided into 4 equal parts, 3 shaded = ¾
Learners’ Activities (Expanded):
Students fold papers into halves, thirds, and fourths, then shade the given parts. They work in groups to draw circles and rectangles divided into equal parts, naming each fraction. They compare which fractions represent bigger or smaller parts.
Assessment Checks:
What is the numerator in ¾?
What does the denominator show in a fraction?
If 2 out of 3 parts of a shape are shaded, what fraction is shaded?
Notes (Expanded & Detailed):
Fractions show equal parts of a whole. Numerator = shaded or taken parts. Denominator = total number of equal parts. Fractions can be represented with drawings, shading, and objects.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Fractions represent parts of a whole. Numerator is the top number, denominator is the bottom number. Examples include halves, thirds, and fourths.
Evaluation Method (Expanded):
Exit slip/quiz: Write the fraction for a rectangle divided into 4 equal parts with 1 shaded.
Teacher will collect slips and provide oral feedback.
Assignment (Expanded):
Draw a circle divided into 3 equal parts. Shade 2 parts and write the fraction.
Follow-up Activity:
Students will look for real-life objects at home (bread, cake, oranges) and show fractions by dividing them equally.
Differentiation / Inclusive Strategies
Use visual aids for learners who need concrete objects. Provide advanced learners with more examples of improper fractions.
