The Math and Multimedia Carnival 13 is published today on Math and Multimedia. If you have not seen any blog carnivals before they can be an excellent way to explore new blogs and learn more about what is available out there!
I will be hosting Carnival 14 here, articles may be submitted using this link. (Submission deadline for Carnival 14: August 27th).
Note that there is now a new page under Reading with links to all the carnivals to date and further information about the type of article required.
