Mathematics is everywhere around you. Be it a bicycle, a search algorithm, or even the scenarios that we encounter in our day to day lives. Can we observe and uncover the mathematical principles animating these phenomena? And can we use these explorations to make learning maths fun? This project invites you to: 1. Pick one object or scenario around you that utilises a mathematical principle 2. Use the object or scenario to create a mathematical game, puzzle, or activity to teach the principle in a fun and accessible manner For instance, bicycles rely on angles and circular motion to achieve extraordinary efficiency and computer algorithms rely on statistical models, probability and logic. Similarly, the reality TV show called “Let’s Make a Deal” or “Khul Ja Sim Sim” (Indian version) popularised the “Monty Hall problem” as a probability-based brain teaser. In the show, you’re given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what’s behind the doors, opens another door, say No. 3, which has a goat. He then says to you, “Do you want to pick door No. 2?” Is it to your advantage to switch your choice? Surprisingly, the principle of probabilistic reasoning leads us to the conclusion that switching the door improves your chances of winning the car. You can pick any such object or scenario and uncover the mathematical principle behind its design. The final output of your project will be to create a game, puzzle or activity that uses the object or scenario to teach the mathematical principle behind it. You can submit your game, puzzle, or activity in the form of a written document, a visual presentation, or a video. The best submissions will be the ones that make learning maths more fun and accessible using an object of everyday use
