Numberphile - Engaging Math Videos


Numberphile is a collection of videos dedicated to math, numbers and other related areas.  Teachers can use these to brush up on topics or post to their class website as a “flipped” learning opportunity.  There are explanations of laws, theorems, and applications.  Here’s one on Pythagorean Primes -  a quick way for students to learn what a Pythagorean Prime is, how to calculate it, and how it can be applied to a right triangle.


Numberphile also show how math is used in the real world.  Check out the video on how stats are gathered at a professional soccer game, or how Nazi Germany created code using an Enigma Machine.  
  
The presenters are intelligent and engaging.   The site is a bit challenging as the home page uses sketches, not text, to title the videos (part of the kitsch is the use of brown butcher paper to draw out the problems).  But it's worth the time to click through them and find the videos that work for you and your class.  The videos are on YouTube – easy to share via link or embed code.  Some even have the transcript available.  They are geared for junior high and high school curriculum.

CC Connection: These videos can help your students understand both the computation and application of math skills.  Specifically they address the specific math practice standards: 1. Make sense of problems and perservere in solving them; 2. Reason abstractly and quantitatively; 4. Model with mathematics; and 7. Look for and make use of structure.
