I have a class of 25 kindergartners with no aide. 17 of my students are boys, most of whom are extremely energetic with no preschool experience. I have been keeping activities short, adding in a ton of movement opportunities, song and dance breaks, etc... but I am still having a terrible time keeping them under any kind of control for longer than about 5 minutes at a time! Our class is falling behind in the curriculum because we are still working on basics like how to walk in the classroom and line up for snack. This is my second year teaching. Last year, my classroom management was pretty great. I am starting to feel like a failure because I can't figure out how to teach my new class! If anyone has any advice as to how to run a classroom with an overwhelming number of rowdy boys (and some girls too!), please help me out! Thanks!
