Classroom Computers Rules Posters are posters that you can display in the computer area(s) of your classroom. They remind the students what they are expected to do while using the computer. I have included a filled in sheet with rules and a blank sheet for you to personalize with your own text. Each set features the title heading “Computer Rules” or “Computer Expectations.” I have also included a blank “OK for the Classroom Websites” sheet. Here you can list the websites that are safe for your students to visit when they use the computer.
