1.Smile if you get near him or see him once he looks at you.
2.Twirl your hair or talk to your fellow classmate acting happy. 'Do not look sad or change your tone. A guy could notice that easily.
3.Make the first move. Most girls don't think they should, but it's normally worth it. A guy would love to know that a girl isn't so shy and is setting a comfortable environment around him.
4.Ask him a question. Guys love that a girl is actually the one who flirts with him first. Once you get to know him better, don't be afraid to start giving him hugs and such because it will help the guy know you like him.
5.Compliment him. You could say, "I like your shirt," or, "I love your hair," but make it kind of casual, guys like feeling confident.
6.Also act as if your flirting, but when you go up to him, just compliment him on something you admire him for. He will feel less pressured to go to you and talk then
Make sure that he is looking, and look at him for exactly two seconds smiling. Don't go any longer than two seconds or else it will turn into a staring contest and that will be sort of awkward.
7.ALWAYS WEAR PERFUME!!!!!!!!
TIPS
1.Be yourself. Don't act like someone you're not. Guys really don't like that.
2.Don't be afraid to be different either. Most guys prefer girls who are not the exact same as every other girl on the planet. Don't feel like you have to fit all the latest trends or do what the popular kids do.
3.Try to look your best when doing this. Do not let other girls get in the way of you trying to impress your crush/ex-crush.
4.Scrunch hair, curl hair, straight and shiny, or do a messy do. It's a hot trend for guys.
