Talk to her.
How to get a girl to like you?
Talk to her stare/glance a bit and then look away when she notices or hold it for 2 seconds then look away. Girls like attention and when they see you they decide that they might actually like you.
Making her laugh will be a good start. William Goo has a good answer "helping," doing something together can be bonding.
Don't be shy, but don't impose. Be a pleasant person and act natural. Find out her interests and look into them. Once you know her ask her out.
Flowers help while talking to her
just be yourself.
