MATHCOUNTS, the national enrichment, club and competition program that promotes middle school mathematics achievement, is sponsoring a video contest.

Open to any US resident in grades six through eight, the contest challenges students to create a video that uses a real-world application to teach the math concept in a problem of their choosing from the 2011-12 MATHCOUNTS School Handbook, freely available for download here:

Four finalist teams will win an all-expense paid trip to the 2012 MATHCOUNTS National Competition, where they will present their videos. Each member of the team that creates the winning video will receive a $1,000 college scholarship.

At the contest's conclusion, MATHCOUNTS will make available a free library of all the videos submitted, indexed to specific MATHCOUNTS problems, math concepts, and standards.

The submission period opened yesterday, and ends next February. Public voting begins 15 November, 2011.

These video math tutorials were created for students by students from Lincoln Middle School (Santa Monica, CA). Using a tablet PC, the screen-capturing software Camtasia Studio, and a "kids teaching kids" model, Eric Marcos' sixth graders have created nearly one hundred clips, most of them less than two minutes in runtime.

Tune into their YouTube channel:

Have a favorite number? Share it — and the reasons for your choice.

Tens of thousands from around the world have already participated in this international survey, part of a research project about how humans relate to numbers. Alex Bellos plans to post results in the coming year.

Until then, catch a preview of the leading contenders for the world's favorite number, other survey trends, and verbatim "numerical love confessions" by reading or listening to the recent segment by National Public Radio Science Desk correspondent Robert Krulwich:
