Subject: Mathematics
Grade Level: Grade 1
Date: Week 35
Lesson Duration: 45 minutes
Week & Period: Week 35, Period 6
Topic: Fractions
Sub-topic: Halves, Thirds, and Fourths
Learning Objectives
By the end of the lesson, students should be able to:
- Define and explain whole, half (½), third (⅓), and fourth (¼).
- Identify and show fractions using shapes and objects.
- Divide simple shapes into equal fractional parts.
Previous Knowledge
Students already know how to draw and identify shapes.
Instructional Materials
Paper folding shapes, fraction charts, fraction circles, chalkboard, textbooks.
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Teacher shows a loaf of bread and cuts it into two equal parts. Learners are asked what happens when something is divided into equal parts.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Fractions are parts of a whole. A whole is one complete object.
Half (½) means dividing into 2 equal parts.
Third (⅓) means dividing into 3 equal parts.
Fourth (¼) means dividing into 4 equal parts.
Teacher demonstrates folding paper into halves, thirds, and fourths. Teacher shows charts of fractions and colors the parts. Examples:
Circle divided into 2 = halves.
Rectangle divided into 3 = thirds.
Square divided into 4 = fourths.
Learners’ Activities (Expanded):
Learners fold paper into equal parts. They use fraction circles to color halves, thirds, and fourths. They draw shapes and divide them into fractional parts.
Assessment Checks:
What is a half? How many parts make a whole? Draw a circle and divide it into 4 equal parts.
Notes (Expanded & Detailed):
Fractions are equal parts of a whole. They are written with numbers: ½, ⅓, ¼. They help us share things fairly.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Teacher reviews fractions and checks learners’ drawings.
Evaluation Method (Expanded):
Exit slip/quiz: Divide a rectangle into halves and shade one part.
Assignment (Expanded):
Draw and divide 2 circles into halves, thirds, and fourths. Shade one part of each.
Follow-up Activity:
Learners will later connect fractions to numbers on number lines.
Differentiation / Inclusive Strategies
Struggling learners work with folding activities. Advanced learners explain fractions with real-life sharing examples.
