I have been subbing for a variety of classes lately, everything from construction techniques to U.S. History. It amazes me what teachers expect (or should I say, don't expect) from a sub. I have watched more movies than I can count. I even talked to one teacher ahead of time, and told him that I was certified in Social Sciences/History, and he said he would make lesson plans where I could actually teach. He still had me show a video for two days, but he allowed me to comment on it as it played. :o( Students and aides in the classes that I sub for tell me that I do a better job than the teacher I am subbing for (not bragging here, just commenting). That is a sad commentary on how complacent some teachers get as they teach day after day. I hope I never get there.
Keep smiling. Have a great day! Stick.
