### Math Teachers at Play: February Break Edition

I had to laugh when I saw this new feature at Let's Play Math called Math Teachers at Play due to the current state of my coffee table:

Taxes done? No.
Windshield wipers replaced? No.
Snow-capped octahedron? Check.

What book is that?

Pistachios...yum!
PS - the word verification I had to put in for this post was 'efers'. Kind of fun.

What a lovely coffee table. Origami rocks. Have you seen the talk on TED (www.ted.com) by Robert Lang on computational Origami. Its about 16 minutes I think, quick and fun.

Kate said...

Sean at least it wasn't motherefers.

Kevin I just watched it - very cool - I've been messing around with origami for a little while (a year-ish) and I had seen and read about some of Lang's work but I like the way his talk put it all together.

I just spent \$30 on paper mwahahaha.

I went through a modular origami phase a few years ago. Man, that was fun time.

Lang's Black Forest Cuckoo Clock is unbelievable. Our local library had his very mathematical text on origami and I couldn't believe the level of his work.

Kate,

A great book for math geeks is "Project Origami" by Thomas Hull. While a lot of the activities are aimed at a college audience, there are a number of fun items for high school. I used one in my algebra 2 honors class where you divide a square sheet into thirds and the proof boils down to the intersection of lines. What I think is neat about it, is that you've got this square sheet of paper with folds and you have to describe the folds as lines. It blew the student's minds that these folds were lines, that they could have equations. Anyway, cool book.

Oh, also, TED has a lot of cool videos. As far as math goes here's a couple more recommendations:

(1)"Ron Eglash on African fractals"

(2) "Hans Rosling shows the best stats you've ever seen"

(3) "Richard Preston: Climbing the world's biggest trees"

I'm a TED junkie, the above are more or less math related, but there are a lot of meaningful videos there and sometimes I just show them to my classes because dammit there's so much going on in the world they should know about.

Kate said...

Kevin I sooooo want that book, but it's like \$50, so I'm going to spend some more time with this one for now.

Thx for the TED recommendations I will check them out. There is some amazing stuff there but the sheer quantity can be a little overwhelming.

Rich do you have any pictures? I'm working on a Cosmos Ball.
