Creating a webpage--www.wikispaces.com--students can sign up and create a webpage individually or collaboratively. It is free and easy to use. I have students post their work on the site and link their page to mine so I can see their work as well as allow them to see each other's.
Creating a super cool online power point presentation--www.prezi.com--another free website that allows students to create amped up power point presentations. It is funky and professional and user friendly and fun all at the same time.
