Hi Adriana ! I am on my way to become a teacher, but I recently had a discussion in class about classroom environment. I'm not sure what age you will be teaching, but classroom circles are always important, whether that be a large area rug or desks that can easily be put in a circle. In my ideal classroom, I would have my desk at the front with a large area rug nearby, a reading corner with comforable chairs (bean bags), any type of shelving pushed to the wall so children are always visible, and classroom expectations hung up in the front. I would keep more of a simple theme and hang up childrens work, but when seasons hit decorate accordingly.
