How to make a move??

I'm not particularly experienced with relationships and well, I want one. Pretty soon. I have someone in mind who I see everyday at school and he's very polite and friendly. I can tell sometimes he wants me to talk to him, but I don't want to be too random and burst out in conversation because well, all we know about each other is our names and that he has an A in that cl and I have a C. What should I say to him? Any suggestions. I don't feel comfortable with asking him to hang out yet. I can be pretty confident If I want, so I don't really need morale boosters, just specific things to do and say to let him know I'm interested
