### Blog Carnival

As I seem to be lacking creative ideas for blogposts on my own blog (though I'm working on two new videos), I suggest you head to Math Teachers at Play blog carnival.

Lots of good stuff there! For example, MathNotations is holding a second (free) math contest, and I found some neat Russian-style "subtraction" problems.

As always, Denise has illustrated the carnival beautifully.
