Mathematics in Movies

http://www.math.harvard.edu/~knill/mathmovies/index.html

If any movie has a scene that discusses your field of work, you immediately develop an interest in that scene. Appreciating this, a Harvard mathematics professor, Oliver Knill, has developed a website called Mathematics in Movies that shows movie clips that include math discussions.

There are no restrictions on the movie or scene type or the type of mathematics being discussed. The site offers these clips to any visitor who clicks on them. Next to each scene, a description is given and you have the choice to either stream the clip in Flash format or download it as a Quicktime file with the M4V format. The M4V format will help any iOS device owners browsing the site with their device looking for math-involving movie clips.

Rhyme and Learn

http://rhymenlearn.com/
Rhyme ‘n Learn is math and science taught by mnemonics.  A mnemonic is a learning aid.  It uses word associations like rhymes so that a term or fact is easier to recall later.  An example of a mnemonic is “In fourteen hundred ninety two Columbus sailed the ocean blue.” 

Rhyme ‘n Learn was created Joe Ocando.  He taught math and science to students of all ages and discovered that many find it difficult to memorize hundreds of new terms and facts.  He also found that rote learning is boring and not very effective for long term retention.  Type a math or science term in the search bar to find a mnemonic for it.

Get The Math

Textbooks and exams are all good when it comes to teaching math, but how do the students know when/how to apply that math in the real world?  GetTheMath is a project that aims to do just that, i.e. teaching students how math is used in the fields of fashion design, video game design and music through simple and short videos.

Once students have watched the videos, they can take online quizzes to apply what they learned to a real world problem.  The website also has a 30 minute video showing how a particular teacher used GetTheMath to teach his kids. High school students can also participate in a math contest to sharpen their math skills.

The website mostly focuses on the use of algebra as compared to other areas of math.
