The first day I would also take time to go over my general expectations for students and then have them flesh-out the details. This is an idea I picked up from Steve who suggested this truncated means of getting students involved while staying on schedule.
I would also want to do something that asks what they hope to get out of this class. I could do this as an exit ticket or maybe an extended survey, depending on what kind of time we have.
The key parts to this first day are that I show the students I care about them, that we all know the procedures in the classroom, and that we all have some idea of where the course might head in the days to come.
