Math Forum Online Course: PoW Class Membership


Registration closes October 7 for the Math Forum's online professional development course "PoW Class Membership: Resources & Strategies for Effective Implementation." The course runs October 7 - November 17.

This course will familiarize current subscribers of the Problems of the Week (PoWs) with the features and resources associated with your PoW membership access. You will be able to make an informed decision about how to start implementing PoWs with your students, and you'll have an idea of further steps to try when you are ready.

Participation requires Problem of the Week membership at the Class level or higher, which you may purchase (or renew) together with the course.

Capturing Teacher Knowledge Study


The federally funded Capturing Teacher Knowledge (TeKno) project at the University of Arizona invites teachers to participate in a study designed to analyze how teachers think about variables, expressions and equations.

Participants are asked to:

  • Complete online surveys about their background and about their knowledge of math
  • View and comment on 12 classroom clips of lessons on variables, expressions, and equations
  • (Optional) Administer a student assessment on variables, expressions, and equations twice, once as a pre-test and again as a post-test, before and after you teach these topic areas

For those teachers completing the task, the TeKno project will provide a $75 amazon.com gift certificate. Participants who collect pre- and post-test data will receive an additional $50 gift certificate.

To register: contact the organizers through this link:


Please include in the note that you heard about this study through the Math Forum. Teknoclips will respond with an activation key for you to register on the website.

PCMI Participants' Blogs


Several of the participants in the Park City Mathematics Institute's Secondary School Teachers Program keep blogs. These bloggers highlight current adventures and experiments in their classrooms and thoughts about math, education, and math education. Recent posts have included these titles:

  • Things I (try to) Never Say
  • Resources for Good Problems
  • Lady Gaga & Exponents
  • Re-Inventing the Wheel Isn't So Bad
  • Riding a Flying Magical Unicorn

How Much Did It Cost Back In ...?


Craig Russell alerted us to this widget from Wolfram|Alpha. It calculates the relative worth of amounts of US dollars dating back to colonial times. Craig suggests using it to explore inflation with students, asking questions such as:

  • How much did a hamburger cost when you were born?
  • Is it relatively MORE or LESS expensive now than it was then?
  • Can you think of products/services that have a different history?
