I am loving my new binder system. I am going through now to highlight with a yellow highlighter so I know which copy is my main copy. But here is my question. Everyone has those teachers at your school who wants to borrow things. What if they want a copy of something in your binder? I know one of my teammates sometimes will come in my room and say "remember that short vowel sheet you had. Can I take it and make a copy." I would much rather make the copy for them so i can get it back but that is not always possible. But sometimes I never get the original back. Many times my teamates takes so much stuff I forget as well. They are no the most organized. When I kept things in file folders I had multiple copies of things so it didn't matter. But now I care. Ideas.
