Check out the mathy blog entries in this month’s Math Teachers at Play blog carnival, hosted by Jonathan at jd2718. Topics range from preschool to high school, including songs, games and much more. Fun!

Welcome to the September 17, 2010 edition of math teachers at play. This is MTaP #30. This MTaP may look a little different. There is no theme weaving its way through and unifying the sections. We are not opening with a discussion of the number 30 (no matter how many cool things we could have come up with), and the sections are, um, different. It has occurred to some of us that the experience a student has in mathematics may differ greatly from p … Read More

Jonathan serves up plenty of fun in this month’s Carnival of Mathematics. And he will be hosting the Math Teachers at Play blog carnival in two weeks — submit your entries here.

Carnival of Mathematics 69

Normally a Carnival of Mathematics opens with a discourse on its ordinal. But 69?

It is 1000101 in binary, 1011 base 4, 105 base 8, 45 in hex… If we used 32 as a base?  25. And that would be 15 in base 64.

69 is odd. But there are as many odd numbers as there are ________. I still love that!  It is one of a bunch of surprises that Dave Richeson lists  at Divisio …

Math Teachers at Play #29 via The Number Warrior

Posted on by Denise Gaskins

After a slight delay, the new Math Teachers at Play carnival is up at The Number Warrior, with a nice variety of blog posts to browse. Enjoy!

Math Teachers at Play #29 The last time I hosted Math Teachers at Play I attempted to start a tradition of including a math puzzle pertinent to the number of the carnival. Alas, it didn't take, but now that I'm hosting again I can mention an old classic: Three people check into a hotel. They pay $30 to the manager and go to their room. The manager finds out that the room rate is $25 and gives $5 to the bellboy to return. On the way to the room the bellboy reasons that $5 … Read More

It’s high time I got back on track with my Alexandria Jones posts, so I’ve been working hard on a short introduction to probability, to go along with The Birthday Surprise. Or, more honestly, I’ve been procrastinating on a short intro … well, anyway, here’s a little of what I’ve been reading around the interwebs lately.

Mathematics and Multimedia Blog Carnival #1 THE NUMBER 1 Welcome to the Mathematics and Multimedia Blog Carnival Number 1. Before beginning, let us see what's so special about 1 as a number. is a homophone of Juan (dela Cruz), the person who represents the Filipino people.  He is just like Uncle Sam of the United States. Hmmm… just a thought, should we change Juan dela Cruz to Manny Pacquiao? is the multiplicative identity. Any number multiplied by 1 is equal to that number. is the only … Read More

Update March 2012

The blog carnival website has been unreliable for several months, which is why you will see strike-through on the paragraphs below that deal with that site. Please read the current information on these pages:

Do you want your blog to grow? One of the best ways to draw new readers to your blog is to get involved in an active blog carnival. Mike wrote an excellent article (What is a Maths Carnival?) explaining how carnivals work and how to submit an entry.

Now, if you’re ready to raise the ante a bit, let’s bring the carnival itself to your blog.

These instructions are specifically about the Math Teachers at Play (MTaP) blog carnival for classroom teachers, homeschoolers, and independent math learners. After all, that’s the carnival I know best. Still, most of the principles should apply to any blog carnival you might want to host.
