Rather than a traditional lecture on the class rules and procedures, get students thinking, discussing and writing about appropriate behavior in school situations. On these handouts, I've described common instances of poor behavior in school and asked students to evaluate the situation and recommend a course of action. Then, as a class, we would discuss what students think should happen. This process calls for more active participation than simply taking notes or listening.
There are five prompts total: entering class, hallway behavior, assembly manners, computer lab etiquette, and missing-work email etiquette.
Each prompt has its own handout, so you can use them for bellwork during the first week (as I did), or divide them up among the class jigsaw-style. Each handout includes a simple rubric for grading.
Files are in MS Word .docx format, so you can tailor them to your class/school values and needs.
