how to hint to the guy who has a crush on me that i like him too?

a couple of months ago i found out a guy in my class has a crush on me. i've noticed him looking at me a lot since too haha. anyway now i've (unfortunately i guess) caught feelings for him and like him back..
it doesn't seem like he's going to make a move, i think he's too shy, but i want to show him subtly that i like him back. it's difficult though as we rarely speak so i don't know how to ask him to hang out without it seeming weird!
please if you have any advice i would be sooo grateful, thank you x
*edit we are both almost 18. (i've haven't got with any guys before so idk what to do!)
