The Playful Math Carnival (formerly “Math Teachers at Play”) is now a quarterly 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.
The Playful Math Carnival is hosted by volunteer bloggers, with the exact day of publication left to the host’s discretion.

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…

Thank you. ^_^

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.
