There are many options out there for school supplies. I recommend the following for my classes. If you choose to deviate from my suggestion, just remember THE MINIMUM requirement is that you have a binder with dividers, lined loose leaf paper, a blue or black ink ball point pen, and a pencil with eraser EVERY class.
My preference ... the tried and true.
1. A 1 1/2" - 2" binder.
2. A spiral bound 100 page notebook (for the chronological organizing and maintaining of notes).
3. Dividers (4 recommended; one for each term and one for loose leaf paper storage).
4. A package of loose leaf, 3-rind binder paper (stored at back of binder; 20 sheets at all times).
5. A pencil case.
6. Several ball point pens (blue and black ink).
7. Several pencils (HB).
8. A white, plastic eraser.
9. A highlighter.
10. A selection of coloured ball point pens or fine liners (for colour coding notes).
11. "white out"
