I think I have too many; 1. My lesson plans and immediate info binder for planning. 2. My back up binder with more detailed info about students, more private info, questionaires, etc. 3. My DATA book, or grade book, with testing results, and other info I need for grading. This info goes into my online gradebook and I'm relying less on this book. Most grading goes right to online. Other binders are standards and subject related. Is this too many? I'm feeling inefficient.
