Whole Class Discussions: Repeat or Ask Question

Students are investigating Salsa Rueda dancing. The question is how to predict if you will dance with every leader/follower given n pairs and only dancing dame k (Salsa Rueda chapter in the Dance Book). Prior to the scene in the video, I asked a student to share her conjecture with the class because she had done the greatest number of examples and I knew that her work would be a great resource for the class. We see the student explain her conjecture. I then ask whether somebody in the class can repeat her conjecture or ask her a question, which leads to an interaction between the students. Notice that I am not involved in this interaction other than gently suggesting a particular example to look at.
This video was taken in a mathematics for liberal arts class with 15 honors students. It met two times a week for 75 minutes each.
