seating arrangement

many time as a teacher i tried to sit bad behavior students alone or let them to chose where they want to be sitting . I can observe that teachers have a good way to organize students in a classroom.
We don't have carpet in our classrooms. I sit them on the floor but i didn't practice it everyday just when I had a game.I can realize that we can sit students on the floor to modelate them the activities.
I liked this way, and i am going to use it. Also I asked teacher if her decide where students sit.She answered me that she decide. She sit four students in a table trying to sit them a high level student in each table to help students with low level. They work together and help among them.It is a good strategy because sometime student understand better between them.I like because students like sit down with students similar to them. So, they don't work. It gives me ideas that i am going to do in my pre-k students.that I feel are a challenge to me because sometime in this classroom with those students i can't have a good classroom management.
