The new Math Teachers at Play blog carnival is open at math hombre for your browsing pleasure:
The carnival features a wide variety of posts about math and teaching, along with 6 puzzle questions and a warning about the “rare but deadly Blogcarnival Catch 22.” Enjoy!

Denise Gaskins' Let's Play Math 
I would be willing to consider hosting an issue of MTaP — let me know what the schedule is and I’ll let you know what could work for me.
The schedule is here, under the “future hosts” tab. Right now we have people signed up through April, which means that May and later are open to be claimed. The carnival is always the 3rd Friday of each month, and a lot of the work can be done in advance, if you want.
I couldn’t do may, but you could put me down for June.
That will be great! I’ll send you an email.
