As previously mentioned, there is a wealth of resources available for helping teach primary pupils how to use the Internet safely. However, if time is short (what really?!) and you can only look at two then try Hector’s World for Key stage 1 and the Cyber Cafe from the thinkuknow Internet Proficiency scheme in key stage 2.
Hector’s World is great for introducing internet safety issues to Key stage 1 pupils. There are a series of lesson plans and activities aimed at younger children. Hector, who is a dolphin, can be downloaded onto your computer and will then float over internet pages. If anything appears on the screen that makes children feel uncomfortable then they can click on Hector Protector who will cover the page and give them a positive message for doing the right thing.
The Cyber Cafe has been recently up dated and relaunched. There are characters in the cafe to take children through the issues they may be interested in such as searching, email, chat and social networking. The site now uses more audio rather than text and comes with free lesson plans and resources.
