classroom expectations

I want my students to come prepared. I understand they will forget their materials, I am more concerned about their minds. I want them to come ready to learn mentally. I want them to try to make my classroom a safe environment for all my students. For some of my 9th graders this is hard for them to do. I want them to respect their teachers, their classmates, and themselves. In the end if they can follow these simple steps all the other struggles I have had as a teacher seem to disappear.
