Search Results: show her i'm interested

So im a high school senior who likes a sophomore girl. I met her last year in a class we had together and we sort of got to know each other. I didn't realize it, but she was flirting with me a lot. She always started the conversation, asked how my day was, complimented my shirt, etc. She said we were practically dating. She said she would have went to prom with me. I liked someone else at the time and I was oblivious, but now I'm really interested in her, so here is what's happened since last year :

She followed my insta out of nowhere before school ended
We didn't see each other over the summer

She said hi to me again on the first day of school. I asked her how her summer went and stuff
She wished me good luck two or three times for games
She always starts the conversation with me
I see her glance at me in the hallways
She plays with her hair as I walk by
She smiles and laughs a lot when talking
Always looks directly at me while talking

Just the other day I saw that she popped up in my Snapchat quick add, so I friended her. She friended back right away to say hi and ask how I was doing. We talked about her sports game and stuff and she always replied quickly and wrote a good amount. She sent both cute and kind of silly pictures, and she's been one of the first to view all my stories since.

Now I want to talk to her more and ask her out soon. I was going to just walk up to her, tell how fun to talk to she is and that I like her a lot, ask her to go out or make plans or something.

Unfortunatly, we hardly see each other at school, though when we do we usually talk or wave and stuff, but I don't know if I should just ask her or maybe continue talking and snap chatting her. We let our conversation go after we both went to sleep, so I'm not sure how to start it again or tell her to start a streak. I know it sounds stupid and I should prob just ask her, but I just really want to know what is going on inside her head.

So Im a senior in high school and I really like this sophomore girl. I met her last year. We had one class together, and I was the only older guy in the class. I only had one friend in the class so I wasn't too social, and she started talking to me around the last few months of the year. I saw her in free sometimes, and she would always say hi, compliment my shirt, flirt a little
We're both pretty popular in our grades and both good looking.

She said we were practically dating (jokingly) once, stole my phone and took pics on it, insisted on taking pictures with me, even said she would have went to prom with me.

She was sending me these signs, but I am clueless when it comes to girls, so I didn't realize under summer started. I didn't see her over the summer. Our only interaction was liking each other's Insta photos and stuff.

Now, a week or so into school and she continues to show she might like me. I no longer have a class with her, so I only see her after school. She starts the conversation, walks up to me, says hi. she's never been very shy and doesn't hesitate to talk to me in front of her (or my) friends, She has wished me good luck in sports games multiple times and asked how my day was going, how was my summer, etc. Now that I like her, too, I've been trying to show her that by doing the same. We can never talk for too long, but we say hi (she usually says hi first), talk a little, ask simple questions and stuff. Lately I've seen her flip her hair around or glance my way as I'm walking her way.

I do think she likes me, but I'm not sure how to let her know I feel the same. The other day she popped up in my Snapchat quick add, and I don't know if I should add her or not. I don't know if it would be weird to add her without actually asking, even through the quick add feature.

Either way, I'm going to ask her out soon, before our sports seasons end. I'm pretty confident she'll say yes, but not 100%. So, is she interested in me and how should I move forward with this?
