A 6 week unit of worked planned using www.wikispaces.com. You can create a free teacher/education profile to use with this. I set it up using the name the children know me by as the username and then a general password so that all children could access the same account and that way they did not need their own usernames. All children could login and edit separate pages at the same time without any problems. Here is the planning as well as the step by step instructions I created for children in booklet form. L3 may need editing with your own print screen to incorporate your wiki name and not mine.
