Previous Knowledge
Students already know addition and subtraction of two-digit numbers
Instructional Materials
Mathematics textbook for Grade 2
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Teacher asks: How many boys are in our class? How many girls? How many in total? Pupils answer.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Population means the total number of people in a group. We can use addition to find the total and subtraction to find differences.
Example 1: In a family, there are 3 boys and 2 girls. Total children = 3 + 2 = 5
Example 2: In a school, 60 pupils are present. If 25 are boys, girls = 60 – 25 = 35
Learners’ Activities (Expanded):
Pupils solve family data problems in groups
Draw population charts and solve questions
Share real data from home and practice addition/subtraction
Assessment Checks:
If 32 pupils are boys and 28 are girls, how many pupils in total?
There are 50 students, 20 are absent. How many are present?
Notes (Expanded & Detailed):
Population concepts show how math applies to real life. Addition finds totals while subtraction finds what remains.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Pupils recap that addition is used to combine groups, subtraction is used to find what is left.
Evaluation Method (Expanded):
Exit slip/quiz: Boys = 24, Girls = 26. What is total population?
Teacher will collect slips and provide oral feedback.
Assignment (Expanded):
Solve: (i) Father = 1, Mother = 1, Children = 3. What is family size?
(ii) Total students = 80, Boys = 35. How many girls?
Follow-up Activity:
Students collect population data from their families and practice.
Differentiation / Inclusive Strategies
Give visual aids for weaker learners. Encourage group discussions for peer support.
