I'm a first year teacher, teaching outside of the age group I received my education in, and I'm finding myself taking way too much time planning lessons. I'm causing myself stress and it's driving me a little nuts. I over analyze my every thought and decision while planning. I put ideas off because "it can go better in another unit" or something like that. I think things are too simple one minute and then too complicated the next. Some of this stems from thoughts of "What if..." I'm never satisfied! I can't just write it up, print it out, and hope for the best, knowing that if it doesn't work out I'll know for next time. I'm sure there are other teachers like me... Do you do this? How much time do you find yourself spending on lesson planning? Do you over analyze like I do? Any suggestions on how to know when to just stop?
