I have chosen to link the Qld Government website for Cyber Safety. It is a program specifically designed for schools with a range of useful resources. I particularly like the Cyber Heroes as they offer a variety of delivery methods to teach children about being safe online, knowing what information to share or keep private, look out for cyber bullies, understand the rules of the online world, know who they are playing/chatting with and practice the pause (think/act before posting online). They use comic cyber superheroes to relate to their audience.
