One of the things I've done this year at my school is pilot a "flipped" classroom. This means that for homework, my students complete their notes either by Powerpoint, video, or Educreations interactive whiteboard presentation from our class site.
It. Is. Awesome.
My students come to class more prepared, and we are able to dive deeper into a lot of the concepts IN class that we wouldn't have time to before. I'm uploading my Powerpoint creations one lesson at a time and will also have a link to download an entire chapter once I am finished with the chapter.
Here's a screenshot of Lesson 1 from Chapter 1 (note: All lessons come from Glencoe's 2010 Geometry edition textbook)
