This is a version of the popular, "Prompt, Prepared, Productive, Patient, Polite" class expectations that I am using this year. I love to use these because they are catchy for students and easy to refer to when discussing behavior and expectations. I laminate these and display them in my room. My students and I review and discuss these expectations at the beginning of the year and during the year as necessary.
I found that I have more success with these in my classroom than with class rules.
