I am a new first grade/first year teacher. I am posting here to get some much needed advice: My class is just great in the morning. They all listen to me and act like they should. However, after lunch and recess it is like I have a whole different class. In the afternoon, they do not listen like they do in the morning. I don't change anything it is the same management system- is it just first graders getting tired-adjusting to school (tomorrow will be the 5th day). I would just really love some advice on how to fix this before I start pulling me hair out?
