I'll be taking maternity leave for my first little one in December. I'll probably be gone January & February. I've talked to other teachers in my school, and some have left multiple binders with instructions for every possible scenario, step by step lesson plans, materials organized into weekly bins, etc... Other teachers have just left lesson plans for a few weeks and then trusted their subs to write them from then on (with assistance from the team). The thought of setting up 2 months worth of plans and instructions ahead of time seems like a daunting task, but I also don't want to leave my sub or my students in a bad place. Does your school have any general guidelines for what should be left over extended leaves? What have teachers at your school done?
