Must haves for school????????????????????

I was wondering what some must haves for a 13 year old girl (going into gr 8) are for school (especially first day and week).I live in a small town and so my school is from JK-gr 8 so we dont have lockers or a cafeteria. we have hooks for our backpacks and eat in our cl. oh and we dont have dif cles for dif subjects, just one calss and usually the same teacher. so i need to know what some things are that i NEED to bring for the first week of school are. mainly for the first day and that i can fit in my backpack. also what are some good lunch options and where can i get all my supplies from???
