I use Edmodo.com, Wikidot.com, Edcavas.com, and Moodle.org along with many other sites to provide resources for my class. I have made a mobile app students and parents can download. Use Appsbar or Yapp.us to create a mobile app for your class. It's easier than you think. It is done right on the web. I also screencast lessons and list them on the mobile app. You can see some of my work at: http://www.youtube.com/user/qmstech

Here is the end of unit review I had available online. I developed these materials over time. Edcanvas is the best way to display them. http://www.edcanvas.com/lessons/RLy3oBFKnGxp8A/impacts-of-technology
