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":

The Mathematical Association of America (MAA) has put out its annual call for pi-related photos:

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 minute-long event to answering your questions.


PoW taking place: math problem-solving 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
