I started a teaching internship today at a high school which will involve a lot of substitute teaching. I was asked to sub for the first time today with no lesson plan and as it was the first day after vacation there was no old homework to go over or new homework to work on. Needless to say, the classes didn't go as well as I'd hoped... What can you do as a sub to keep a high school class going when you don't have a lesson plan or direction? How do you motivate students when they know the busy work isn't assigned by their teacher or graded? I appreciate any help or teaching tips for a newbie! Today I was taken totally off guard, but I want to be more prepared for next time.
