Math Links for Week Ending October 31st, 2014

It's Halloween so here is a new one from our Engaging Math blog. It is a review of proportional reasoning with a Halloween theme.

I thought this was neat. A Teacher asks students to create a problem. The student creates one that has to do with Starwars. The dad posts the problem on Facebook and it somehow gets to JJ Abrams (the director of the current series) and he responds with a problem of his own. It really does speak to the power of the Internet and social media. Thanks to Mark Esping for this one.

I am starting to clean up my Geometer's Sketchpad files. I have a bunch of sketches that I am slowing moving over so they are iPad compatible. Here is the first one. It's a practice file for determining the distance between two points. You can download it at the link below and see how it works with this video.

I like activities that take the more mundane aspects of math and pimp them up a bit. And you can always count on Julie at I Speak Math to do the "pimpin". In this one its all the parallel line properties. I like the part about putting the lines on the floor and especially the Dance Dance Transversal video.

I have always thought that playing games was good for numeracy. Whether it is rolling dice or something like guessing. It's all good for helping students become numerate.

In preparation for Pi Day Next year (March 14, 2015 will be 3.14.15) here is a new video from Numberphile where they literally create a mile of Pi. That's a million digits (spoiler alert, the last digit is 1). Actually they didn't do it because of Pi Day but because they have surpassed 1 million subscribers on their YouTube channel. That is pretty cool. This video has everything. Fun Pi facts, interesting number sequences, Feynman points, quad copters, you name it. And if you want a fraction of that mile then you might try printing the first 1000 digits here.

More from Name This Data. I mentioned it before and here are a bunch of new ones. They are mostly US referenced but I still really like the idea of showing some data and then asking what it could be of. Try it in your classes.
