What to do when a guy keeps staring at you?!

So there's this cute guy in my class and he always does this thing where he just stares at me?! I have this thing where I don't like being stared at, so I'm always like "What..?" & he'll just keep looking at me! Is there anything I can do to like flirt with him? I'm pretty cool about flirting.. I don't do anything big like winking or blowin' kisses so.. HELP!
