I subbed for the first time this past week. 2 days in a 4th grade class, and one day in a TOUGH 3rd grade class. Both teachers provided a detailed, almost minute to minute lesson plan. HOWEVER, It seems to me that sticking to the lesson plan to the letter is almost going to be impossible some days, with some classes. The combination of being disoriented with the new class and procedures, and the increased noise level and behavior problems on "sub" day will mean I'm just going to have to reschedule the day at times, even skip the Math, or Health lesson or something just to gain a cushion of time. I was fine with the 4th grade class, I finished them an hour early both days and we played games. The 3rd grade class? I was 15 minutes behind all day and could barely control them enough to give them the lesson. Any thoughts?
