Make sure that you visit your classroom before the first day of class. You should learn the fastest route from your office or previous class to your quiz section, because you are bound to be late some time. You should check whether the room has a chalkboard or whiteboard, and whether or not it has an overhead projector. Most rooms have overhead projectors and either a whiteboard or a chalkboard. Always take whiteboard pens and an eraser if your room has a whiteboard, or overhead pens and write-on transparencies if you plan to use the overhead projector.
You should confirm the room assignment by looking at the department's course listing in or outside the main office (Sieg 114) on the first day of classes.
