Are you required to leave emergency sub plans? If so, you may want to use a choice board! My art colleague Sharon had the idea to make a choice board that can be used multiple times if there is a situation where you need to be gone unexpectedly (sickness or unexpected quarantine). Even if your school does not require this, I highly recommend having a stash of lesson plans ready to go in case you wake up sick in the middle of the night. No one wants to be writing lesson plans when they are feeling crummy. Other things to leave for your substitute teacher include: seating charts, class lists, detailed instructions of your schedule and procedures, and emergency plans (tornado, fire or lockdown).
Here is one of my choice boards that I am leaving for a substitute teacher. You can get the free PDF download here.
