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

Math Links for Week Ending July 14th, 2017

I have liked @Desmos' Polygraph from the get go. So it seems odd that it has taken so long for someone to take it offline. In this case it is @Mr_Stadel who has come up with a nice hack to do them online. And all it requires is some plastic sleeves and whiteboard markers. He's done Lines and Parabolas so far. Why not add your own?

More tips from @Mr_Stadel on using Polygraphs in class. This time it's using the idea of a word bank to help students (and a list of "taboo" words that students cannot use). The idea is to help students use more academic language while using Polygraphs.

And Finally from @Mr_Stadel's quest to maximize the use of Polygraph, he introduces the idea of a PolyGraph "Word Jar". Watch the video below and then follow the link for more info on how to use it.

Math Links for Week Ending July 7th, 2017

A few weeks back @ddmeyer and @Desmos came out with a Desmos activity on graphing points that dealt with fruits. Not much later @BenOrlin created a bunch of his own images on various topics. Check them all out at the link below.

Some neat @desmos activities. This first one is for limits and continuity in Calculus

The next activity is for trig functions with a classic adaptation of the hours of daylight data.

It's more than just making things fun or exciting for kids in math. Students need to be emotionally engaged in what is going on. I feel like that is true for just about any subject but here are some ideas to help that process. Thanks to @KMarkPet for pointing this one out.

It took me a while to figure out that this was hot sauce. But I guess the questions is, what math can you suggest with this?
