Math Blogs: Creating a Virtual Community of Problem Solvers" which focused on student blogging at the grade 3-5 level. I was hoping for more discussion about math blogging in general but the turnout was promising for more sessions in the future.
After a quick run through the exhibit hall, I joined Neil Cooperman to prepare for his session entitled The Great Green Globs Contest, and More.
We had a small, but enthusiastic group of educators who once again convinced us of how special this program is in motivating students to do advanced mathematical thinking. The program is available from the authors at Greenglobs.net. Information about the contest is available here.
