# Numberphile: a series of numberly videos

What it is: Numberphile is a series of “numberly” videos by Brady Haran.  This is the same guy behind some other great projects including periodicvideos and sixtysymbols.  These videos reveal some of the mystery behind numbers and math in fun, short snippets!  I could give a long, drawn out explanation about the site…but really, you should go have a look and play a few videos. Or, try out the video below:

How to integrate Numberphile into the classroom: Numberphile can make a math geek out of anyone, myself included!  I don’t tend to geek out very much about numbers or math, but show me pattern and reveal some of the mystery that numbers hold and I am in.  This is what Numberphile does beautifully!  Numberphile would make a fantastic opening for math class.  Start each math class with these short videos to get your brain’s math muscles working.  I’ve watched 3 videos in a row and I am seriously geeking.

Ask students to each choose a different video to watch.  Students can learn a new math “trick” or pattern in math to teach their classmates.  The goal: creatively teach the concept!  They could create their own video, stop motion animation, infographic, story, illustration, etc.  Hold a math day  (3/14 would be fun…pi day) where students get to spend the day teaching one another.

You may assume that these videos are best for older students, not so!  At Anastasis, our 2nd and 3rd graders had a ball learning about Fibonacci and will happily explain it to any who enter their classroom.  Find an area of interest and share the passion!

Tips: All of the videos on Numberphile are YouTube videos.  If you don’t have access to YouTube in your building, try one of these methods for accessing the videos:

• SafeShare TV- This site lets students watch YouTube videos without ads, links, comments and related videos.  You also have the option to crop videos and share videos with a unique URL.
• YouTubeXL- This is a service that YouTube provides that lets you watch videos on large screens without the ads and comments. Neat tip: if you time “quiet” before the YouTube url, it takes you to a safe page where you can watch a YouTube video.  WAY cool and easy to do on the fly!
• Clean VideoSearch- This site lets students search through YouTube videos without the comments, ads and busy sidebar.  It has additional features like the ability to choose how many videos you want to see on each page in your search.
• Clea.nr– This service (a browser plugin) deletes all of the obnoxious extras that hang around videos (ads, comments, related videos). You can also search YouTube without all of the extras showing up.
• ViewPure– This site cleans out all the clutter and gives you just a video.  Bonus: There is a quick button that you can add to your browser so that you can go to a video, click on “Pure” in your bookmark bar and instantly have a clean video.
• Dragontape– This service lets you drag videos into a timeline and share them easily with students.  This is great for mashing up several videos, or cropping multiple videos into one.
• Movavi– This is a video conversion service. Wonderful for teachers who can’t or don’t want to access a video directly from YouTube.  Copy/paste the url you want to convert, choose a file type, done!
• Zamzar– This is another great video conversion service.  Works quickly and easily!
