Promo for NCTM Indy 2011 mtg: Pseudo or Real?

I just got this postcard in the mail promoting the upcoming annual 2011 NCTM Conference. Notice that there is some math embedded in the image. I can see four. Can you find them all?

Of the four only one is "real." The others I would argue are candidates for being pseudocontextual.* Do you agree?

*See Dan Meyer's blog entry regarding pseudocontextualizing in math especially if you haven't heard of Dan Meyer who has captured the math blogging online world by storm.

Computational Thinking, Google and Dan Meyer

In Dan Meyer's latest blog he writes about his project at Google on Computational Thinking. Google, one of the premier forces trying to reinvent the paradigm for teaching and learning, looked to a bunch of high school math teachers for help. Follow Dan's take on all of this starting with his blog entry.
