The first day of class can be stressful, painful and nervousness all around. The best way to break the ice is to get to know each other. I draw a big + [plus] on my board and after introducing myself, I asked each of my students to come to the front of class.
They will introduce themselves and write their name and reason for taking the class. I ask them to tell us their expectations as well. In the end, this is a good exercise in networking and breaking the ice. Good deal all around!
