What is the speaker doing?

Good morning, my name is Marsha, and I’m a senior in the Math Department here at Madison.(17)Today Greg and I will be taking you around to a few places you’ll be visiting a lot. Before we start though, (18)does everyone have a copy of the map of the campus? You should really keep this with you for the first couple of weeks. At least until you become familiar with the buildings and landmarks. You sure wouldn’t want to miss any classes this early in a term. Today, we’ll visit some of the most important places in campus. First, we’ll go to the registrar’s office there you’ll sign up for your classes. So if you haven’t seen your advisor yet, you can wait in the commons outside while the others get their class schedule. You’ll have to come back here on your own later. Next, we’ll go to the library. I think you’ll be pretty impressed with the rare book collection. And finally, (19)we’ll go to the cafeteria, where you’ll probably spend a lot of time socializing, at least until your first exams are scheduled. The number of the rooms for your lectures will be on the schedule you’ll get from the registrar and(20)it’ll be up to you to find those rooms yourselves. So, if there’re no questions, we’ll start the tour now.
