Wow! Do you have a Union? Because that sounds like a violation. Our instrumental teachers have schedules like that. I wouldn't want it. But if I did I would really concentrate on literature. I wouldn't do a lot with papers, work sheets, or internet. You can do a lot with focussing on reading, discussion, and comprehension. Remember, you have to carry things from school to school. So just carry books. Make things as simple for yourself as possible.
Good luck. Concentrate on what you like, not on what you don't like. Hopefully that will keep you going.
I have tried to email you several times but it bounces back. Perhaps if you email me first it will get through.
I agree with Donna, try 'Library Skills" for your classes. As a Librarian, you are confident with the knowledge and all materials are in your Library. It doesn't need to much time to prepare it. You may start with circulation desk stuff, spine labels (it will help you if your school library has different colors of spine labels), Library maps, Fiction and Non fiction and simple steps to find a book. The level of K-5, they really need the basic information about their school library and as a teacher we need to repeat the information again and again. Good luck.
