To "open up the professional development usually locked up at
these kinds of conferences," math teachers at last weekend's
regional conference and exposition of the National Council of
Teachers of Mathematics (NCTM), held in Chicago, and at the
annual conference of the California Mathematics
Council  Northern Section (CMCNorth) gathered together
virtually at the new MathRecap site to blog about

Amy Ellis: Laying a Foundation for Learning to Prove

Farrand, West, and Stetson: Problem Solving as PD for
the CCSS

Michael Shaughnessy: Reasoning and SenseMaking: Keys to
Student Engagement

Karen Arth: Mathematical Modeling

Karen Arth: Making Functions in Algebra Active
and Interesting

Lisa Nussdorfer: Using the iPad in the
Mathematics Classroom

Kyndall Brown: Access, Equity, and the Standards for
Mathematical Practice
The Forum's own Suzanne Alejandre copresented twice at
CMCNorth. See outlines for the last three conferences where
our very busy Director of Professional Development has
presented in the past month, download her PowerPoints or PDFs,
learn about grant opportunities, and access rich problems,
scenarios, and other resources from her blog:

PoW taking place: math problemsolving moment of the week

"Notice how Matthew wrote out his calculations in words before
he put the numbers in. That really helped me tell if his
calculations made sense."

 Max, commenting on the PreAlgebra PoW's latest solution

8 Math Talks to Blow Your Mind
http://blog.ted.com/2012/11/21/ 8mathtalkstoblowyourmind/
TED, the nonprofit "devoted to Ideas Worth Spreading," recently
selected videos of eight talks that "breathe life and logic
into everyday problems." The clips range in runtime from four
minutes to eighteen:

Ron Eglash: The fractals at the heart of African designs

Dennis Wildfogel: How big is infinity?

Arthur Benjamin does "Mathemagic"

Scott Rickard: The beautiful math behind the ugliest music

Margaret Wertheim: The beautiful math of coral

Benoît Mandelbrot: Fractals and the art of roughness

Michael Mitchell: A clever way to estimate
enormous numbers

Geoffrey West: The surprising math of cities
and corporations
Since 1984, TED has brought together people from the three
worlds of technology, entertainment, and design. For over a
hundred more TED Talks on math, start here:

Now taking place: math education conversation of the day

"When I received an invitation to be part of the Ignite!
presentations at CMCNorth 2012, I was both honored and
terrified! I had seen my Math Forum colleagues prepare and
present at NCTM 2011  Indianapolis and
NCSM 2012  Philadelphia. I wanted to be like them and give an
Ignite! talk but I didn't want to feel the pressure ... so ...
I kept it a secret. It really happened, though...."

Math Matters, the Contest
http://www.siam.org/careers/matters.php
Math Matters flyers reveal the mathematics behind everyday life
and the technologies we encounter. Appropriate for elementary,
middle, and high school students, the series continues to grow
since we first featured it in these pages three years ago. As
part of this applied mathematics awareness campaign, the
Society for Industrial and Applied Mathematics (SIAM) has also
translated six of these free onepage PDF flyers into Spanish.
SIAM recently announced a contest seeking ideas for new Math
Matters. To win one of the three cash prizes that total $500,
submit one page of text before the deadline of next Friday,
14 December, following these guidelines:

which begins at $25 for fulltime students enrolled in any
college or university:

"The development of the 3rule you show is pretty good. Of
course, another aspect is to see that this can be extended
indefinitely for any number of digits. I like it, thanks. My
son isn't quite there yet, but soon."

Math Girls 2: Erratum, and Update
http://bentobooks.wpengine.com/2012/11/ announcingmathgirls2fermatslasttheorem/
Last week's feature on Math Girls 2 contained a misstatement.
MG2:FLT is a novel, and is the sequel to Math Girls. The
Kickstarter campaign was for the manga (comics) version of the
original Math Girls novel.
Bento Books are doing final editing of the Math Girls comic,
which they expect to publish early next year.
Marion Cohen, who teaches math and writing at Arcadia
University, recently reviewed Math Girls 2 for the
Mathematical Association of America:
