I really like the idea of having multiple class activities to pull from. I can see how this would be so helpful because class dynamics change a lot from term to term. Sometimes I have over 30 students and sometimes I have 8. There are some activities that are really difficult to do with 30 students and vice versa. Not only is the number of students important, but the personalities as well. I really liked the airplane activity and I am wondering what other class activities instructors in the forum have done that have proven successful in helping the students interact and learn, and in helping the instructor to get a sense of class dynamics?
