Celebrate Pi Day Thursday, March 14th
http://mathforum.org/t2t/faq/faq.pi.html
Celebrate Pi Day in your math class Thursday, March 14th! Check
out the Forum's Teacher2Teacher FAQ for Problems of the Week,
Ask Dr. Math conversations, book suggestions, and other web
resources on the theme.
NCTM has selected Pi Day articles, too, as well as
Illuminations' activities and resources "just for fun":

Marcus du Sautoy has organized a free live event starting at
1:59 PM Greenwich Mean Time (8:59 AM ET):
http://oxfordconnect.conted.ox.ac.uk/
Open to anyone, Pi Day Live invites the public to find the
infinite decimal using one of four suggested methods, and then
share results. du Sautoy, the Charles Simonyi Professor for the
Public Understanding of Science at the University of Oxford,
will devote the last 15 minutes of the 50 minutelong event to
answering your questions.

PoW taking place: math problemsolving moment of the week

"David's other method of finding the ratio is one that nobody
else came up with, and I just really wanted to share it!
Alicia's solution is interesting because she sets up the
problem as a ratio right from the start. Another way to solve
the problem (which happens to be my favorite) was ..."

Now taking place: math education conversation of the day

"I'm wondering if anyone has already created a simulation for
the 'Penny Lab' from College Preparatory Mathematics (CPM).
They graph the data on an overhead and then the teacher layers
the overheads to show the overall trend. Then we write a
theoretical equation to represent the experiment. I don't know
how to handle this sort of recursion with TinkerPlots (TP)."

Daily Desmos
http://dailydesmos.blogspot.com/
Last week, three teachers began posting a new plot every day
and asking, "Can you create the following graph using
desmos.com or some other graphing tool?"
Daily Desmos was inspired by a challenge tweeted from Dan
Anderson (Saratoga Springs, NY) that Michael Fenton (Fresno,
CA) and Justin Lanier (Brooklyn, NY) enjoyed solving. Focusing
less on sophisticated, uncommon functions and more on clever or
subtle uses and combinations of elementary functions, the trio
rate each Cartesian challenge by difficulty — and welcome
others to play:

Desmos is a free online graphing calculator that zooms in and
out of plots, offers slider bars to explore parameters, and
switches between Cartesian and polar coordinates, among many
other features. For more about Desmos, including their staff
picks of "Creative Art," visit
