This diigo list site hosted by Anne Bubnic links to a number of digital citizenship lesson plans (or a variety of grades).

Great spot to make connections with teachers, students, and classrooms abroad. This wiki is hosted by Michael Graffin out of Perth, Australia.

Kid-friendly news articles for teachers, parents and kids. The great thing about this site is that it allows you to track current events and make classroom learning relevant to the real world yet the articles are written at a level (e.g., vocabulary, sentence structure, concepts) that most middle school kids can easily follow. The site also provides lesson plan guidance for teachers if they wish.
