Math Teachers at Play

Dan has posted Math Teachers at Play 17 at his mathrecreation blog. (There were two issues of MTAP #15, so this is really the 18th issue.) I've been negligent about linking to each issue of MTAP, so here's an archive of links to all the past issues (click on 'past posts').

Two of the posts I especially enjoyed:
John Cook has posted on the math behind musical scales in his posts Circle of fifths and number theory and Circle of fifths and roots of two at his blog The Endeavor.

Alison Blank has put together an inspired and inspiring Prezi presentation, Math is Not Linear, and posted about it on her blog Axioms to Teach By.

I added quite a few blogs from this issue to my already long list at Google Reader. I think I'm really going to like the quirkiness of this blog:
Vlad Alexeev shows us an impossibly small book of impossible figures in the post Mini Books of Anatoly Konenko at his blog Mathematical Paintings and Sculptures.
Next issue is in two weeks, right here. After that, it looks like we're switching to a once a month schedule, on the 3rd Friday of each month (with Carnival of Mathematics taking 1st Fridays).


  1. I never noticed that about doubling number 15! Will you straighten out the numbers with your next carnival?


  2. Sure. So I'll be doing MTAP #19, and there will never be a MTAP #18. Is that what you have in mind?

    If that's what you want, I hereby proclaim a contest to see who can come up with the funniest or most compelling story about what happened to the numbers from 15 to 19.

    If my book (Learning Math Outside the Classroom and In: Stories from Math Circles, Homeschoolers, and the Internet) is published, the winner can have a copy of my book. (If they remind me of it after the book has come out.) But mostly you get the glory of having your story in the next MTAP. :^)
