How to discover 22/7 and other rational approximations to $\pi$


A short article written for a magazine that caters to high-school students. The basic idea is to use continued fractions found using Euclid's algorithm, and then to chop off the continued fraction to get rational approximations. Written at a high-school level. Some of the material was already present in my book Maths Concepts.

Update: March 2014. This article is published in "At Right Angles." Here is a link to the published article.
