Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Teacher asks learners to count objects in the classroom such as books or pencils. Learners solve quick oral drills: 3 + 5, 9 − 4, 2 × 3.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Teacher defines addition as putting numbers or objects together to find the total. Example: 23 + 16 = 39.
Teacher defines subtraction as taking away or finding the difference between numbers. Example: 54 − 28 = 26.
Teacher defines multiplication as repeated addition. Example: 4 × 3 = 4 + 4 + 4 = 12.
Teacher shows vertical and horizontal arrangements:
Horizontal: 25 + 34 = 59
Vertical:
25
+34
59
Teacher introduces word problems: A boy has 12 oranges. His friend gives him 8 more. How many does he have now?
Teacher uses arrays for multiplication: 3 × 4 = 3 groups of 4.
Learners’ Activities (Expanded):
Learners solve addition, subtraction, and multiplication problems using objects.
Learners draw arrays to show multiplication as repeated addition.
Learners practice solving simple word problems in groups.
Assessment Checks:
Solve 46 + 27, 92 − 48, 6 × 7.
Notes (Expanded & Detailed):
Addition uses the plus sign (+). Subtraction uses the minus sign (−). Multiplication uses the times sign (×). These are the three basic operations of arithmetic.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Teacher reviews definitions and examples of the three operations.
Evaluation Method (Expanded):
Exit slip/quiz: Learners solve one addition, one subtraction, and one multiplication problem. Teacher collects and gives oral feedback.
Assignment (Expanded):
Solve: 32 + 45, 76 − 28, 5 × 9.
Follow-up Activity:
Learners at home count and add or subtract objects like pencils or fruits.
Differentiation / Inclusive Strategies
Teacher pairs stronger learners with weaker ones and uses real objects for clarity.
