PoW taking place: math problem-solving moment of the week
"This problem could be done, alternately, by dissecting the
larger triangle into nine congruent smaller triangles: the
black triangle is the smallest triangle we started with. Since
the triangles were constructed on trisecting parts of the big
triangle, they are all congruent (several methods would work)."

Math Girls Writing Contest
Want to dazzle the Mathematical Girls narrator with one of
Miruka's elegant solutions to a tricky problem? Is there some
topic from the fundamentals of mathematics that you want to
teach Tetra? Well now's your chance!
The translators of this popular Japanese young adult novel
about math, first announced in these pages in October, invite
readers of all ages to participate in a mathematical writing
contest. Just write a dialogue between the Math Girls
characters that discusses an important mathematical topic or
problem in the style of the book, and submit it before the
Sunday, April 15th deadline.
Thanks to generous sponsorship from Wolfram Research,
publishers Bento Books will award prizes of
Now taking place: math education conversation of the hour
"In my experience, however, students don't really think about
things and how they're applied. They want to get it DONE, not
understand it. They want an A, not an education. It's
incredibly frustrating. Most of my AP Calc students can't graph
a line in the form y = mx + b. It makes me want to tear my

A new interactive math exhibition made its worldwide premiere
in Washington, DC, this past weekend.
Designed for families and students, MathAlive! at the
Smithsonian Institution brings to life the real math behind
video games, sports, fashion, music, robotics, and more. At
MathAlive! you can
race friends on snowboards in a 3D experience
jump into a fractal dance party
design and play your own video game
capture a 360-degree image of yourself
control robotic satellite arms
Through these and dozens more unique, interactive experiences,
the MathAlive! exhibit takes math from its native form into the
applied worlds of design, engineering, technology, and science.
The freely downloadable Teacher's Activity Guide includes
Fly as High as Kobe
What a Million Looks Like
Tessellate or Not?
24 Frames per Second
Spin the Wheel
Pick Your Pixel
Design a Robot Arm

The weekend after the Fourth of July, the 5,000 square foot
exhibition arrives in Arizona, then goes to Alabama September
22nd, with twelve more cities already slated for 2013.
The national exhibition and presentation at Smithsonian are
made possible by Raytheon, and were developed in collaboration
with the National Council of Teachers of Mathematics (NCTM),
the National Aeronautics and Space Administration (NASA), the
National Society of Professional Engineers, MATHCOUNTS, the
Society of Women Engineers, and MathMovesU.
