I summarized some of my thoughts on math game design for the upcoming online event February 3rd, which is a part of CO12 (Connecting Online 2012) conference. In particular:
- Defining intrinsic math game mechanics, and why we want them
- Taxonomies for math game designers
I would very much like comments about my slides, which are here:  https://docs.google.com/presentation/d/10gG23rJdWKwdDh4sWgj9uYptx4XSiFKmYbeAk0YUT94/edit
The presentation will happen online on February 3, 1pm Eastern Time, and is open and free. You can log in here: http://www.wiziq.com/online-class/701943-math-game-development-communities-and-networks
