Thirty6: A fraction tool

This is a fraction tool that I call “Thirty6” It includes a game board (red) and a variety of game pieces. Although you can use it for any purpose you want, this is how I propose that it's a tool for exploring collections of fractions whose sum is 1. When you cover the board completely with a set of tiles, you’ve collected a set of fractions whose sum is 1. For example, you could cover the board with the brown (½), blue (¼), green (1/6), orange (1/18), and yellow (1/36) tiles. That means that ½ + ¼ + 1/6 + 1/18 + 1/36 = 1. How cool is that!?
