Long Pause

It has been a long time between entries. I have had so many different experiences and classroom experiences between then and now. Tonight I am a bit exhausted and emotionally overwhelmed. I am "guest teaching" in a K/1 split with 16 students. 2 of these students receive services and my inexperienced guess is that 2 more need them. Then you layer the age difference, developmental difference, and academic challenges on top and my overriding feeling of where do I go, how do I improve what happened today (and yesterday). How can I teach kids who need a nap after lunch, are 5-6 years old and aren' t going to bed until 10 or 11 at night for an early start school.
The fact that I am a sub, with a limited knowledge of the kids routines, doesn't really help any of us. I remind the children about 4 times a day that I am not their teacher, and though she left me notes, and we will DO all the things she left me notes about - it might sound different or they might have a new partner or any of the other myriad deviations to the way it has been since the beginning of this semester.
