THE GUY I LIKE ISNT IN ANY OF MY CLES...HOW DO I TALK 2 HIM? I NEED AS MUCH ADVICE AS POSSIBLE!?

im in 8th grade. the 1st day of skool was 2day and i only saw him once. he isnt in any of my cles and i rele wanna c/talk to him!!! how do i do that without it being obvious that i like him? we arent friends...more like acquaintences (sorry...i probably butchered the spelling). we were in the same homeroom last year but now i dont see him at all! the only time i'd see him is in chorus. and if i get into this singing choir/group that you have to try out for to get into it...my voice teacher says i'll def. make it but i dont wanna wait until it starts (thats probably in like october or november...=[...) to talk to him. how do i make a casual conversation with him? without making it obvious that i like him, please. HELP ME!!! I NEED ADVICE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
