Option 1. Take a moment to browse TED-Ed by subject area or by series. Click through the “Quick Quizzes”, “Think” and “Dig Deeper” activities. Bookmark any that look relevant to your teaching so that you can come back later and watch the video.
Option 2. Take one of your favorite teaching videos and create a lesson around it.
