Math Links for Week Ending July 21st, 2017

I love this series of dynamic sketches on exterior angles from @dynamic_math. It's the visual nature that I like the most and the fact that you really get the idea of the fact that the sum is 360 (regardless of the polygon). I have done something similar here using Geometer's Sketchpad (I should turn it into a websketch) but I think I like the way this works better.

I can't decide whether I like this or not. In some ways it reminds me of the old MathBlaster type games where the math was embedded in a game that already existed but as I played this Tetris game with embedded factoring, I just wanted to play more. Maybe that's because I used to love Tetris. Thanks to @ddmeyer for pointing this one out.

The idea that when you have student centred learning leads to pushback from students is not new. In my opinion a lot of that comes from students who find it easier to just be told what to do. I don't think they are actually learning better in that traditional setting but students like it because it is so passive. When you have student centred learning, they actually have to work. None the less, I like this sketchnote from @Wheeler_Laura on the topic. Follow the link for more details.

I'm a sucker for anything about primes. Here's a new @Numberphile video talking about the distance between large primes. I was particularly interested in the algorithm for showing the distance using factorial notation. But the crazy logarithmic expression in the proof is something that should turn any grade 12 student's head
