I’ve known about TED (Ideas Worth Spreading) for quite a long time but although I found their videos very interesting I thought they were too long or too difficult for my classes. Now TED has launched a new site, called TedEd, 
with a collection of educational video lessons you can choose by subject and view in class or assign as homework. Every video is accompanied by a lesson with Quick Multiple Choice questions that check your general comprehension. If you have one wrong, you can always check with the video hint and you can also have Think questions that further explore the topic.
For teachers , one of the most powerful features is the FLIP THE LESSON where you can customize the lesson by editing the title, giving your own instructions, select or deselect any multiple choice questions…etc.
This is a lesson I have flipped for my students. I used the video Questions No One Knows the Answer To to give my students some practice using Reported Speech Questions. You can see my lessonhere
