I have created a PowerPoint presentation for teachers, which looks at the mathematics in The Simpsons. You can find out more about the nerdier side of The Simpsons (& Futurama) in my book “The Simpsons and Their Mathematical Secrets“.
PowerPoint presentation: click here>>> The Mathematics in The Simpsons for schools
Each slide contains notes for teachers, which you can see in the normal view.

I hope to create some more resources soon. Follow me on Twitter (@SLSingh) to find out the latest news.
