It's probably best to stick to going over your syllabus, introducing
yourself to your students, and having them introduce themselves to one another.
Since this is a workshop course, the earlier they get to know one another
and feel comfortable discussing assignments together, the more smoothly your
workshops will go in the future. If you have a Tues./Thurs. class and don't want
to let them out too early, the PHG cookie exercise works well on the first day. It gives
them some early practice with writing detail, they get to work together, and
most importantly, you provide them with a tasty snack that will endear you to them
for the rest of the semester.
