The October 2nd Math Teachers At Play blog carnival will be hosted here!
You have until Wednesday, September 30th to submit, but there's no time like the present to start thinking about what you might share. Remember that you don't have to share stuff for the classroom--there's a reason it's not called Math Teachers At Work. Personally, I'm always interested in logic puzzles and discrete math conundrums, and questioning the way statistics and other numbers are manipulated (especially in the news).
First, read the September 18th MTaP, hosted at the Math 2.0 Interest Group.
Then, submit your article for the next MTaP here.
Also, you might want to check out MTaP #6, which was hosted here back in May.
