This week was the beginning of my rotations with the students. In my classroom, there are two instructors and myself. We have decided to slit each class (three classes total) in to thirds and then each of us takes a third of the class. Then every twenty minutes we rotate the students; allowing us to interact with all the students in the class during the 1.5 hour class.
During my twenty minutes I introduced the students to the Euler characteristic for a polyhedra in a plane. This was done via the Game of Criss-Cross found in the Circle in a Box put out by the MSRI. My goal is to progress this idea for the next few weeks.
