Welcome to the Math Teachers At Play blog carnival — which is not just for math teachers! If you like to learn new things and play around with ideas, you are sure to find something of interest.

Let’s start the mathematical fun with a couple of puzzles in honor of our 20th edition: First, the shape to our right is an icosahedron, one of the Platonic solids. Each face is an equilateral triangle — can you count them? For more fun, make your own model.

Math Teachers at Play Changes

This month, our Math Teachers at Play blog carnival switched to a once-a-month schedule. We’ll publish the third Friday of each month — which is this week!

Teachers, homeschoolers, or anyone else who enjoys playing around with math: Wednesday night is the deadline to send in your thoughts, ideas, tips, or tricks about math using this handy submission form. Posts must be relevant to students or teachers of preK-12th grade mathematics. Old posts are welcome, as long as they haven’t been published in past editions of this carnival. Most bloggers have interesting gems buried in our archives. Why not dust one off and share it anew?

Hosts Needed

With the schedule change, I also need to rebuild the queue for hosting the Math Teachers at Play. If you blog about teaching or learning in grades K-12, and if you write about math at least occasionally, I would love to have you consider hosting the carnival sometime. Here’s how to sign up:

  1. Check out the schedule on the “future hosts” tab at the MTaP home page,
  2. pick a month that fits your schedule,
  3. and then let me know.

And don’t worry if you’ve never hosted a blog carnival before — it’s easy, fun, and great publicity for your blog! I’ll send you a detailed email of instructions to get you started.

Carnival of Mathematics #59

Welcome to the Carnival of Mathematics! We’ve got a full roster this time, including roller coasters, topological Turán theory, a mathematician arrested as a spy, a plane running out of fuel mid-flight, speed limits in Conway’s Game of Life, and much, much more…

The 59th Carnival of Mathematics features 59 blog posts (counting the multi-part posts and the carnival post itself) on a wide variety of interesting topics. Drop in and enjoy the browsing!

Check out the new math carnival to discover plenty of great fun for all ages:

Are you wondering where MTAP #18 went? Here’s the story (contest-winning entry from Lisa Downing), and we’re sticking to it!

“The Odds were at odds with the Evens. It never seemed fair to them that two Odds made an Even but two Evens didn’t make an Odd…”

Contest: Write a Number Story

Math Mama is hosting the next Math Teachers at Play blog carnival (submit your post here) on Friday, and she writes:

The Math Teachers at Play blog carnival came out twice as #15. Since then we’ve had #16 and #17. We’d like to iron out the numbering, and so the upcoming issue will be #19. I am personally sponsoring a contest for the best little (ie, very short) story written about how the numbers got mixed up this way…

For more details, check out her blog post:

Beginning next month, the MTaP carnival will change its schedule, coming out on the third Friday of every month.

If you are interested in hosting an upcoming carnival, please let me know! Carnival posts are a lot of fun to put together, you get to discover new (or new-to-you) bloggers, and you almost always get a bit of a traffic spike. And don’t worry if you’ve never hosted a blog carnival before — just ask for my very detailed “how to” email to help you get started.
