Chinese Year of the Dragon

http://www.yummymath.com/2012/year-of-the-dragon/

Chinese New Year begins on Monday, January 23rd. This will be the year of the Water Dragon. The year name is a combination of 10 "Heavenly Stems" and 12 "Earthly Branches," creating a sequence of year names that repeat every 60 years.

YummyMath.com offers free Microsoft Word and PDF files for students to explore the least common multiple (LCM) of these two cycles while becoming a little more aware of Chinese culture. Solution files come with a membership to Yummy Math, which start at $12 a year.

An instructional math coach and a retired math teacher created this site to provide teachers and students with mathematics relevant to our world today. Browse chronologically or by category for more of Yummy Math's activities centered around annual and current events, which in coming weeks will include the Super Bowl and Valentine's Day.


PoW taking place: math problem-solving moment of the week

"First, they collected information, so I did as well. Then, I strategized and began to backtrack. I figured out that I need to find how many degrees is 1 hour. So in other words, the unit rate."
- Jaylene, highlighted in the Pre-Algebra PoW's Latest Solution

user_groups/mathematics/default.aspx

Rex Boggs recently started up a new user group on the Promethean Planet site.

The scope of the Technology in Maths Education User Group will include

  • Web 2.0 sites
  • free and commercial software for math education
  • the use of iPads and other touch screens in the math classroom
  • online videos

Boggs moderates the tinspire Google Groups discussion, featured in these pages three years ago, as well as the math-learn Yahoo! discussion group, which the Forum has freely archived in read-only format since 2001:

Now taking place: math education conversation of the hour

"There used to be a classic construction on New York state's old geometry Regents exam that required a student to divide a given segment into any number of congruent parts. In your example, the ratio is 3:4, so there will be 7 parts. Depending on how the question is worded, there would be two answers. If you need further info as to how to do the construction, let me know."
- Bobbi, posted to the secondary (grades 9-12) discussion group of the Association of Math Teachers of New York State

W|A Lets You Audible NFL Statistics

http://blog.wolframalpha.com/2012/01/13/

If you typed these queries into a typical search engine, you'd get a few million links to wade through:

  • Ravens postseason sack yards
  • Patriots fourth down attempts
  • Giants on grass
  • 49ers TE yards per reception

But thanks to data from global sports statistics company STATS LLC, Wolfram's computational knowledge engine now tackles these natural language queries with ease.

Not only does Wolfram|Alpha answer immediately with specific, accurate results about every National Football League (NFL) team, game, and player from the past 25 years, it also automatically generates bar charts and other visualizations — a real boon for those talking points at the Super Bowl party ... and for next season's fantasy football league!

For an overview of the summaries, comparisons, and instant rankings of the NFL since 1985, as well as a gallery of examples, check out Wolfram's complete guide to pro football statistics here:
