Math Forum Handouts from T³ Chicago


Did you miss us in the booth area or during our sessions at the recent T³ International Conference in Chicago? Want copies of our handouts? Feel free to access the printed matter distributed during the conference, including information on our Professional Development program and samples from our Problems of the Week program.

For more information on our sessions or the conference in general, see


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)."
- Jasper, highlighted in the Geometry PoW's Latest Solution

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 Mathematica licenses.

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 hair out!"
- Angela, posted to the ap-calculus discussion group



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 twelve activities:

  • Fly as High as Kobe
  • Design Challenge
  • H2Ohhhh!
  • What a Million Looks Like
  • Tessellate or Not?
  • Fibonacci Flowers
  • Got Rhythm?
  • 24 Frames per Second
  • Secret Code
  • Spin the Wheel
  • Pick Your Pixel
  • Design a Robot Arm


To plan your field trip to the Smithsonian, visit


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.
