How do I get to know my Crush?

Ok so I really want to ask out this girl. But I don't want to go stairs ugh tout and ask her out without really knowing her. So what do I do to get to know her. This is a tricky one for we have no classes together and I only see her After school or at lunch. So what can I do between maybe locker periods or those times? Thanks, just trying to plan everything out leading up to me asking her out haha.
