How can i remember my high school teams basketball plays?

Hi I am in 9th grade, made my high schools basketball team. I have a good shot, and Great ball handler. But i have to sit on the bench because i cant remember our plays. I need to know a way to keep these plays memorized and i was wondering if anybody knows a way to keep them in my head. Thank you.How can i remember my high school teams basketball plays?
Just study them like a big test. Know them, and practice them. Ask someone to give you play numbers and then do the play. If that doesn't work, try writing them on your hand or something. Hope you remember them!
