I don't know what to say to ?

There's a guy, who I find good looking, I think people have told him I like him, which I don't. But I would like to get to know him more, I spoke to him the other weekend at my friends party, and he is really nice. But im really bad when it comes to boys! I don't know what to say? Or how to approach him. I don't want to come across as annoying or anything! I'm not in school for two weeks due to work experience and a trip! And then I have one week left, so I want to Talk to him and stuff before we break up for summer!! Please help :)
