Instructional Materials
Mathematics textbook for Grade 3
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Teacher asks: “If you have 7 slices of cake and each cake is divided into 4 slices, how many whole cakes and slices do you have?”
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
An improper fraction is when the numerator is greater than the denominator. Example: 7⁄4. A mixed fraction is a whole number with a proper fraction. Example: 7⁄4 = 1 ¾. Equivalent fractions are different fractions that show the same value, like 2⁄3 = 4⁄6. Mixed fractions can be added and subtracted if they have like denominators. Example: 2 ⅓ + 1 ⅓ = 3 ⅔.
Learners’ Activities (Expanded):
Students convert improper fractions to mixed fractions and vice versa. They solve problems with addition and subtraction of mixed fractions. They practice drawing fraction models.
Assessment Checks:
Convert 9⁄4 into a mixed fraction.
Find 2 fractions equal to ⅖.
Add: 2 ⅚ + 1 ⅚.
Notes (Expanded & Detailed):
Improper fractions can be changed to mixed fractions by dividing numerator by denominator. Equivalent fractions can be made by multiplying numerator and denominator by the same number. Mixed fractions can be added by adding the whole numbers and then the fractions.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Improper fractions can be changed to mixed fractions. Equivalent fractions represent the same value. Mixed fractions with like denominators can be added and subtracted.
Evaluation Method (Expanded):
Exit slip/quiz: Change 11⁄5 to a mixed number. Add 3 ⅔ + 2 ⅔.
Teacher will collect slips and provide oral feedback.
Assignment (Expanded):
Convert 10 improper fractions into mixed numbers.
Follow-up Activity:
Students practice identifying equivalent fractions with fraction strips at home.
Differentiation / Inclusive Strategies
Provide number line diagrams for visual learners. Challenge advanced learners with unlike denominators.
