Like many of you, I suspect, I learn more and am edified more by the social media math education community than that of academia and your typical district instructional coaching.  Also like many of you, I suspect, I’m WAY behind on my math ed blog reading. Much of that is because it just slips through the cracks: if you’re offline for, like, a day you’ve missed out on all sorts of great twitter conversations and/or blog posts. It’s also partially due to the explosion in math blogging this year. Thanks in no small part to some of the pioneers of the math blog world, and specifically by Sam Shah’s amazing project, math blogs are everywhere, which is an amazing thing. But it’s also quite unwieldy  There are amazing math blogs that I’m probably not even aware of. That’s insane when you think about it. Less than two years ago I could probably rattle off just about ALL the regularly updated math blogs, and now I can barely keep up with those.

So I’m in need of some holiday reading material. Instead of snuggling up by my fake fire with a good book, I’d like to snuggle up with an e-reader or something and read through your favorite several pieces of math blogging from 2012. Don’t give me some stupid “EDUBLOG” ranking: I want to know what touched you and inspired you this year. Maybe it was a wonderfully written reflection piece, maybe it was just a cool problem idea. Both of those modes and others can be found below: just SOME of my favorites from 2012.

There are ten of the pieces of math ed blogging that I found to be helpful, inspiring  well-written, creative, and/or moving this past year. I would really appreciate it if you let me know what was one (or several!) of your favorite pieces of math blogging this year in the comments. You know: take a penny, leave a penny. Thanks, and Happy Holidays!

    Kate on technology: “You don’t go to a twenty-minute inservice about and go “I’m going to make an lesson.” You use for your own purposes, or you suspect its utility and put it in your back pocket, until your awesome instruction idea needs in order to exist. Your lesson is the fuel and is the oxygen.” Love this! (

    Finally, I got a kick out of witnessing Dan’s incredulity at the restaurant over Marc’s golden rectangle claim and Dan’s resulting post. (

    Malke writes about homeschooling her daughter, and has so many cool observations (this one and this one look good).

    I’ll posts some links I’ve been saving up once finals are over, too.

  4. Thank you for the opportunity to share my favorites with you. If you really have nothing better to red, there is, of course, my math blog, begun in August with the math bloggers initiative, Then, I fell I,n love with math blogs reading Math Tales From the Spring. One of my favorite posts was from Fawn, at, because she is so dang funny, Julie at I Speak Math for introducing me in the blogging initiative and I love Mr. Vaudrey ‘s blog for several reasons, he’s funny, risky, and loves his baby girl. Happy holidays to you, Amy in Sebastopol.
