This file contains three different computer safety poster templates. Students can fill in these templates with different ideas for keeping computers safe and keeping themselves safe on the poster. I tried to stay vague with "computer safety" so that they could be used for a variety of things: computer class rules (aka-taking care of the computers), online safety, etc.
Typically, I read the story Arthur's Computer Disaster when my students make these posters.
The first page also contains a computer word list that can be cut out or projected.
