Math Links for Week Ending Sept 15th, 2017

So there is a relatively new math podcast out: My Favourite Theorem is hosted by @niveknosdunk and @evelynjlamb and each episode they interview a mathematician and ask what their favourite theorem is. There is only a few episodes now but so far there is a mix of theorems well above gr12 to things that could be used in grades below gr12. Each episode is relatively short so it's a nice little podcast that you could listen to to get some neat ideas for class. For example, how about this video from 1966 about the mean value theorem. You can get all the podcasts and transcripts at this link but you can get more descriptions and extra stuff at the Roots of Unity Blog.

I have always heard about Casting out Nines but never really knew what it was. It's actually pretty neat and it's a great way for your students to practice their math facts while practicing their math facts.
