Many fans of YouTube enjoy the comedy skits or song clips on a daily basis. Teachers have been using this site for great classroom purposes, too. I thought I'd share a few of my favorite educational channels that don't really feel like you're being educated, but you really are!Reading RainbowAny fan of the old PBS series will immediately love the videos that build background knowledge. I especially like the video field trips and book reviews by kids.TINGOEDThis site features challenging vocabulary words-such as paradox,brawny and supercilious--and explains them using visuals and video clips. It's a quick and fun way to introduce students to amazing words.Math AnticsI really like the way this guy explains intermediate and middle school math concepts such as fractions, factoring and percentages. He has a video for almost anything, and the graphics really help illustrate each concept. He also adds humor--which can't hurt in math class!Smarter Every DayScience concepts can be the most difficult to grasp at young ages. This channel gets you hooked right away with titles such as "How Houdini Died" and "Slow Motion Flipping Cat." I can always find something interesting to learn!Mr. Beat's Social Studies ChannelI just found this one, and it's a great way to share captivating stories from history. They're working on a whole series on the presidents. Mr. Beat offers important civics taught in a fun and engaging way.I hope you'll try out some of these channels and share some of your favorites with me.
