Here is an example of a flipped lesson. In this one, "Just how small is an atom" you have the video, then the other materials to the right. This is a public lesson, but you can take it and flip it, make it your own, and make your own private URL for your class.
TED-Ed now has a new way to flip lessons. Now in beta at ed.ted.com you can redo lessons or create lessons from scratch using TED or any youtube video. The nice thing is that you can see who has completed lessons. These videos give you tours and information. Time to test this. Yet another reason to unblock youtube and make peace.
For those who don't have a lot of technology, this type of lesson (tested in Nepal) that uses colored paper clips to introduce Algebra warms my heart. Algebra is an important subject and using simple manipulatives is a great technique for many classrooms around the world.
