 Lesson Development
Step 1: Revision of Kobo 
Show kobo values:
1K, 5K, 10K, 20K
Pupils read aloud with teacher.
 

Step 2: Addition of Kobo 
Explain: “Addition means putting money together.”
Examples:
5K + 5K = 10K
10K + 5K = 15K
10K + 10K = 20K
   
Step 3: Subtraction of Kobo 
Explain: “Subtraction means taking away money.”
Examples:
10K − 5K = 5K
20K − 10K = 10K
15K − 5K = 10K

Step 4: Class Activity
Give pupils simple questions:
5K + 10K = ___
20K − 5K = ___
    
Evaluation
Ask pupils:
What is addition?
What is subtraction?
Solve:
5K + 5K = ___
10K − 5K = ___

Conclusion 
Summarize:
Addition means putting together kobo
Subtraction means taking away kobo
Praise pupils for participation
