Here are the rules I use in my classroom. I go over them at the beginning of every school year and refer to them as necessary throughout the year. I like that I can also discuss some vocabulary words with my students. FYI, the difference between Excellence and Challenge yourself is that I tell the kids that you always have to try your best (for excellence) and that sometimes things will be hard, but instead of saying, "I can't" we say, "I can!" (for Challenge yourself). Also, for Participate, we talk about doing what you are supposed to do, when you are supposed to do it. Thanks!
