The Playful Math Carnival (formerly “Math Teachers at Play”) is a monthly collection of mathy fun: tips, tidbits, games, activities, and more.
It’s like a free online magazine of mathematical adventures for teachers, parents, and students in preschool through high school. If you like to learn new things and play around with ideas, you are sure to find something of interest.

Would You Like to Host the Carnival?
The carnival is a joint effort. We need more volunteers.
Classroom teachers, homeschoolers, college professors, unschoolers, or anyone who likes to play around with math — if you would like to take a turn hosting the carnival, please speak up!
How to host a carnival, in Six Easy Steps …
Step 1: Get Signed Up
Check the list of the upcoming editions above. If a future month isn’t listed, assume it’s free. Choose an open date that fits your schedule.
Please email me directly to let me know your choice. Or leave a comment below this article.
Step 2: Receive Submissions
Post a “Call for Submissions” request on your own blog and social media accounts a week or two before your carnival, so readers can submit entries directly to you.
We welcome entries from parents, students, teachers, homeschoolers, and just plain folks. Posts must offer a playful approach to some topic in school-level mathematics (that is, anything from preschool up through first-year calculus) or recreational math. Old posts are welcome, as long as they haven’t been published in recent editions of this carnival.
Don’t rely on submissions, though, because you may not get anything worth using.
You’ll need to fill out the carnival with favorite links from your recent online browsing. In the months when I’m hosting, I start a folder on my bookmarks bar to collect goodies for my carnival.
Step 3: Sort Out the Spam
Keep in mind Dan Meyer’s warning, Stop Linking To “Top 100 Blogs” Lists.
Even if a submission is not spammy, you do NOT have to include it in your carnival post if you don’t want to. Sometimes people submit posts that feel too commercial, or that just don’t fit the “playful math” theme.
The carnival is a guest on your blog, but you are still in charge. Don’t feel obligated to post anything that makes you feel uncomfortable.
Step 4: Write Your Post
You decide how much effort you want to put in. Writing the carnival can take a couple of hours for a simple post, or you can spend several days searching out and polishing playful math gems to share.
I try to start writing a draft of my carnival post long before my deadline. I collect pictures (good advice on finding pictures here) and quotations whenever I find something I like, and enter them into my post ahead of time. If I have the framework in place, then all I have to add at the last minute are the article links, and the job doesn’t seem overwhelming.
Make sure you have the right to use any image you post. Either create a graphic yourself or find something marked “Creative Commons” — and then follow the CC rules and give credit to the artist/photographer.
Step 5: Add Something Extra
We don’t have a fixed pattern for what a carnival post should look like.
Our partner carnival, the Carnival of Mathematics, traditionally begins with trivia about the carnival number, and many Playful Math Education hosts have followed in their footsteps. Others have introduced their carnivals with riddles or puzzles about the carnival number. (See, for example, Carnival #20.)
If you’re feeling truly creative, you can even try a themed carnival, like the Women of Mathematics Carnival (#115).
Somewhere within your post, it’s nice to add a link to the current edition of the Carnival of Mathematics. They in turn should link back to your post — or rather, the next edition of the carnival should do so, if they remember. In this way, we help support each other.
Step 6: Time To Publish
Putting together a carnival can be a lot of work, but I hope you will enjoy “meeting” new friends through the articles you find. I love that part of being a host.
When your carnival is finally published, you may want to email or tweet all the people whose articles you used and encourage them to mention the carnival on their own blogs or social media. Whether you send out a request for links or not, you will almost certainly get several math teachers sharing your post. Everyone has been very supportive that way.
I think that’s everything you need to know about how to host a carnival. But if you have any other questions, please ask.
And thank you for volunteering to host!

Hi, I would like to volunteer to be a host of the Math Education Blog Carnival on my math blog:
http://mathtuition88.com/math-blog
Thanks and have a nice day!
That would be great! I’ll send you an email…
Hi, I would also like to volunteer to be a host to this carnival. I find really great. Here is my math blog:
http://lifethroughamathematicianseyes.wordpress.com/
Thank you. ^_^
I would love to host the carnival! I’ve been following along for awhile and now feel like I’m ready!

I would love to host a carnival…www.theothersideoftheequation.com
I’d love to host the carnival Sept. 2017.
Thank you, Iva!
In recent months, we’ve only gotten a few entries through the carnival submission form. So I suggest you begin now to bookmark anything you find interesting to include in your carnival.
I would like to try hosting, if I may. My blog’s at https://nebusresearch.wordpress.com and its most regular feature is a Reading the Comics of the past week’s mathematically-themed comic strips, which I think might be recreational enough.
Joseph, I tried to send you an email. But since you didn’t respond, I assume that got lost in the ether. Please take a look at the schedule above to find a month that fits your life, then email me at “lets play math at gmail dot com” so I can set that date aside for you.
Hi Denise, I would love to host a playful math carnival on my mathy/Montessori blog: http://www.Montessoricosmos.org. Thanks!!
Great! I sent you an email.
