The Mathematics of Beauty

This is a great resource for introducing the golden ratio and examining ratio in the real world. I have tried it with students in year 7 to 11 and they all seem to love the task. I usually get students to work in pairs and get them to measure each other, then have some of the groups measure the celebrity faces. It is a good idea to get them to complete the worksheet before revealing the value of the golden ratio as this prevents people fixing their data. I have included some celeb photo's but obviously these can be changed to suit. I have also included a brief powerpoint showing some examples of the golden ratio in the real world.
