this is awkward

I feel like a child asking this question lol but how do I approach someone I see all the time? There's this guy that I've had most of my classes with in my university, we have the same major. I always see him around campus but we never talk, I want to approach him first but I 
don't know how. I never approach anyone first bc I think that if a guy wants to talk to me, then he'll make the first move.. any advice?
Edit:
This quarter, we only have one class together which is an excerise science class so there's not much to talk about there
