Numberphile is a neat YouTube channel about fun number facts. There are currently thirty-three videos in the Numberphile collection. The videos cover things like 998,001 and its Mysterious Recurring Decimals, Pi and Bouncing Balls, and 1 and Prime Numbers.
Google launched YouTube.com/Teachers as a resource for educators everywhere to learn how to use YouTube as an educational tool. There are lesson plan suggestions, highlights of great educational content on YouTube, and training on how teachers can film their own educational videos. This site was designed/written by teachers for teachers and we hope it’s the first step in really kick-starting a community of YouTube-using educators.
