How do I talk to this guy?

Today was the first day of the spring semester at my college and the first day of my new Biology class. I immediately locked eyes with this cute guy in a beanie within the first few seconds of him passing my seat to sit down in the row to the left of me. He kept casually turning to the side trying to make it seem like he was looking at the professor but I could so tell he was trying to kind of stare at me but not make it obvious. I don't know if he has a gf, I just know his name because the professor called attendance. I want to talk to him Wed. when I have class again, btu I don't know how w/o looking creep! Help!
