1. Divide students into groups of 4 or 5.

2. Each group will select a loan scenario (for example, a loan for buying a smartphone, a laptop, etc.).

3. Groups should define the principal amount (P), the monthly interest rate (i), and the duration in months (n).

4. Using the formula J = P * i * n, each group will compute the simple interest.

5. Calculate the total repayment amount using M = P + J.

6. Each group will prepare a brief presentation explaining their scenario, the calculations performed, and their findings.

7. Present their results to the class, fostering discussion about the different interest rates and terms chosen.

Apply the simple interest concept in a practical setup and enhance teamwork and presentation skills.
