"The Center for Safe and Rsponsible Internet Use has developed a new framewsork for addressing these issues under the overall concept of Cyber Savvy Schools." This site has some good materials and teaching resources for teaching cyber safety. I noticed that there are resources all the way to Kindergarten and more coming.
"Today's kids connect,
create, and collaborate through media. But who helps them reflect on the
implications of their actions? Who empowers them to make responsible,
respectful, and safe choices about how they use the powerful digital tools at
their command? Our Common Sense Parent Media Education Program and our Digital
Citizenship Curriculum give educators, administrators, and parents the tools and
curricula they need to guide a generation in becoming responsible digital
citizens."
