In this course, you’ll learn all about Platonic Solids, and you’ll do it by making a model. This is easy since I supply you with PDF worksheets so you can cut out the outlines, and then put the model together with sticky tape. Having seen how the Platonic Solids inscribe inside one another, we will then calculate and compare their volumes and surface areas … there is also a downloadable worksheet for this.
The Platonic Solids often come up in Maths tests and problems, and having a good understanding of them, means you will recognize them and find solutions quickly. They are also a thing of wonder and beauty. There are only five, and they have been known about since the time of Plato in ancient Greece, or even longer. They were often seen as being key to understanding nature, be that the makeup of the world around us, of the orbits of the planets, or whatever. Nevertheless, this is a Maths course, and I’ll show you how interesting mathematically they are.
