First, a rule of thumb: You need to get anything you will need on a regular basis, even if it is provided by the school. These are basically your backup, your emergency supplies, for the times that the supplies aren't provided or you don't have time to get them. So make sure you have the following, even if it is packed away in a box in your closet:
- Dry erase markers or chalk in various colors (depending on your board)
- Permanent markers***
- Post-It Notes
- Scotch tape
- Stapler, staples and a staple remover
- 3-Hole Punch (even if you don't use 3-ring binders in your classes, some of your students will, and you might use it yourself)
- Locks (for whatever doesn't already have one)
- Rulers
- Scissors
- "Art box" containing colored markers, pencils, and crayons
- Highlighters
- Paper clips (big and small)
- Rubber bands***
- Pens and/or pencils
- Quality erasers (I recommend Sanford's Magic Rub)
- Ream of printer/copier paper
- Extra notebooks and folders (just a few, and not any type in particular)
***WARNING: These items tend to grow legs and disappear faster than you can say, "Welcome back to school!" You must keep them in a place where students can't get to them (preferably locked), and watch over them carefully when students are using them legitimately.
