Thing 3 (Register Blog)

In teaching Geometry, I could see posting assignments on a blog and then encouraging my students to post questions when they struggle with a concept.  One thing this may provide is a forum for students to help each other get through difficult parts of the assignment and not just give up and wait for someone to show them how to do it the next day.  I often see students that if they struggle on the first problem, they give up.  However, when they get some assistance to work through the first problem, they start to find they know how to solve the subsequent problems.  Additionally, this would provide feedback to me on what my students understand or don't understand, which would guide me on how much I may need to reteach versus going forward in the lesson.
