At the beginning of the year, I compile a notebook for those days I have a sub. I include copies of class schedules, attendance forms, discipline policies, and procedures for everything from bathroom to how to borrow a pencil from met. I also include a list of nearby teachers, jobs we have in our class, who rides what bus and so on. I include several emergency lesson plans. I keep this three-ring binder on my desk so it will be handy.
