This lovely tiling by dragon fish is the result of a yearly workshop for industrial design students at the Eindhoven University of Technology. You can read more about the work here.
This is another piece from the 2013 Bridges Mathematical Art Gallery.
Here is another installment in my series reviewing the NY State Regents exams in mathematics.
An all-too-common pastime among math teachers is laughing at the absurd, contrived contexts employed by textbook and exam writers to make problems real-world and engaging. Here are two examples from the June 2013 New York math Regents exams.
Years ago, thinking of the triangle as a garden or corral was enough to make finding its area sufficiently real-world. But I guess now it needs to be kicked-up a notch, say, by taking it to the Australian Outback!
Here’s another classic example.
You know what really gets students engaged in math problems? The word RAP. The best part is that the set A isn’t even used in the question.
The water jets firing normally from these coils converge in a mist along the helix’s central axis, giving the appearance of intersecting radii.
Through Math for America, I am part of an ongoing collaboration with the New York Times Learning Network. My latest contribution, a Test Yourself quiz-question, can be found here
Test Yourself Math — September 18, 2013
This question is about the enormous amount of debt accumulated by college students in the United States. The total amount of debt recently passed $1 trillion; what is the average amount of debt per student?
In October, I will be running a workshop through Math for America titled “Professional Development Through Social Media”. The goal of this two-hour workshop is to provide an overview of the opportunities for professional growth, collaboration, and reflection that teachers can find on various social networks.
As part of the workshop, participants will be invited to peruse interactions–posts, comments, exchanges, conversations–that highlight the nature and strengths of the various digital professional communities. I have a number of good starting points in mind, but I’d love to have more.
I invite you to leave a suggestion in the comments. Provide a link to something great and give a brief description of what this highlights about the online professional world. The workshop will include both math and science teachers, so links to non-math resources are definitely welcome. And please feel free to suggest your own work!
Thanks in advance for your help. Assuming this is successful, this post itself will become an example of the value of being connected!
