CTL 2012: The Write Angle for Teaching Math

I had the pleasure of running a workshop at this weekend’s Celebration of Teaching and Learning in New York City.  The workshop explored ways to inspire and structure student writing in math class, and was sponsored by Math for America.

In addition to the workshop, I wrote a companion piece for the CTL’s Edblog, titled  “The Write Angle for Teaching Math“:

The incorporation of writing into math class has played a pivotal role in my development and evolution as a math teacher.  This article discusses some of the ways I get students writing about math, both technically and creatively.

Writing in math class opens up a whole new world for both teachers and students.  Give it a try!  You might be surprised at where it takes you.

Celebration of Teaching and Learning: In the Classroom

I will be running an “In the Classroom” workshop at the 2012 Celebration of Teaching and Learning.  The conference is organized by New York and New Jersey public television stations, and hosts over 10,000 educators from around the world.

My workshop, “That’s a Good Question!” will focus on inspiring and structuring writing in math class.  It will run on Saturday from 2:30 -3:45 pm.

I am honored to be presenting at this conference, and proud to be doing so as a representative of Math for America.

Enjoy the Celebration!

Math Encounters: Craig Kaplan on Math and Art

Craig Kaplan’s Math Encounters talk, “Revolution and Evolution in Math and Design,” was a whirlwind tour of the design space that lies at the intersection of computer science, mathematics, technology, and art.   Kaplan, a professor of computer science at Waterloo university, is an innovative software engineer, an accomplished artist, and a passionate and engaging speaker.  His talk wove together the mathematical and cultural history of Islamic art, tilings of the plane, non-Euclidean geometries, and the mathematics of aesthetics.

The Math Encounters series, sponsored by the Museum of Mathematics, strives to bring mathematics to the public through dynamic speakers, meaningful topics, and engaging interactivity.  In that spirit, after the talk Kaplan and George Hart led a fun, collaborative workshop where the audience teamed up to create a work of art themselves!

Using some tape, some scissors, and some clever mathematics, each group turned their table into a “tile” using the techniques Kaplan covered in his talk.

And as each group finished their “tiles”, we started putting them all together!

It was a fun and fitting end to an inspiring and mind-opening evening!  You can learn more about Craig Kaplan and his work at his webpage.

A Quadrilateral Challenge

Here’s an easy-to-understand, remarkably rich question that arose during a recent Math for America “Bring Your Own Math” workshop.

If a quadrilateral has a pair of opposite, congruent sides and a pair of opposite, congruent angles, is it a parallelogram?

I had a lot of fun thinking about this problem on my own, discussing it with colleagues, and sharing it with students.  At different times throughout the process, I felt strongly about incompatible answers to the question.  For me, that is a characteristic of a good problem.

I encourage you to play around with this.  I was surprised at how many cool ideas came out as I worked my way through this problem, and I look forward to sharing them!

Weavings and Tilings

At the Bridges Math and Art Conference in Portugal I learned quite a bit about mathematics and weaving.  One of the many simple and fun ideas I left with was using weaving to explore tilings of the plane.

With some graph paper to plan your tiling, some pre-cut construction paper to assemble them, and some patience to work through the process, you can produce some nice results.  Here are some examples from a recent Math for America workshop I led on Math and Art.  More images can be seen on my Facebook page.
