TED-Ed is a website that acts as a portal for finding education videos. Videos are organized by broader themes, such as the inventions that shaped history. Instructors who want to use videos that are directly related to the subjects they teach can visit another page, where videos are organized in more traditional categories such as the arts and Math
The website serves educators and students across grade levels. Educators can contextualize lessons to their classrooms by adding questinos, follow-up suggestions, etc.
The website was launched in 2012 by TED as an extension of the popular TED talks
