In my second year of Uni, 2011, I decided that I would spend a decent amount of time finding the best of educational YouTube channels. I watched a lot of YouTube. A lot. Most of it was drivel, but here’s my up-to-date list of stuff you should probably tune into by topic.

## Mathematics

- Numberphile: Interviews with professional mathematicians from all over the world, usually explaining some interesting piece of mathematics. Not all school-appropriate, but consistently enjoyable. Top three best picks:

- 3Blue1Brown: This one is super-advanced. I did a degree in mathematics and was pretty hazy on most of the stuff he talks about, but what I really like are his visualisations of different concepts. They’re all pretty long form. Top three best picks:

- Singingbanana: Dr James Grime goes through some interesting piece of mathematics, sometimes responding to some new event or anniversary in the mathematical calendar. He’s crazy enthusiastic and often has little mathematics challenges which are fantastic. Top three best picks:
- Grimes Dice (or, more threateningly, Non-transitive Dice)
- Married Problem
- How Predictable are You?

- Standupmaths: Previously a maths teacher and now a super nerdy comedian, Matt Parker walks you through some really cool stuff. My Top Picks:

- Vihart: “Doodles from maths class”, usually linking ideas visually and in surprising ways. Perhaps a little esoteric for most kids, but I find them really entertaining and she often approaches concepts from the left field. Top three best picks:

- Mathsgear: Showcases a bunch of different mathematical props you can potentially get for your classroom that illustrate some mathematical principle or that use some interesting mathematical thinking. Top three best picks:

- Mathantics: Good general-purpose maths tutorials aimed at middle-schoolers etc

- Khan Academy: Same as above, but for a wider age range. Some kids don’t like the American accent, but when I’ve used it in class, they all say it’s pretty handy being able to rewind the video and watch them at their own pace. I sometimes find that I’m not a fan of how he explains things so, like everything in teaching, it’s always worth watching it ahead of time. Sometimes I’ll pick just a couple of his videos, sometimes I’ll supplement it with my own using Camtasia and my Surface Pro 4 and sometimes I’ll use a whole module of his, usually through his site so that the kids can gain points and level up (which they like).
