Children grasp the idea of compound interest by visualizing how money multiplies over time. This activity uses balloons to represent increasing amounts, making the concept of growth tangible and exciting.
Using balloons for visualization taps into embodied cognition, as children see and feel the growth. The physical act of popping balloons after inflating them repeatedly reinforces the concept of exponential growth through a fun, memorable experience.
1. Gather 5 balloons and a marker. 2. Write different amounts of money on each balloon (e.g., ₹10, ₹20, ₹30, ₹40, ₹50). 3. Inflate the first balloon and tie it. 4. For each subsequent balloon, inflate as before but add an extra ₹10 to the amount. Tie each balloon. 5. Once all are inflated, pop each balloon in sequence and observe how much money you would have if you saved each amount for 5 years at 10% interest! 6. Discuss with a family member how much money you’d have after 5 years.
