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."

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."

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
