IAS/PCMI Applications Due for Summer 2013


Reminder: apply by Thursday, January 31st, to attend the 2013 Summer Session of IAS/PCMI, the Park City Mathematics Institute (PCMI) of the Institute for Advanced Study (IAS). This three- week residential program takes place in Park City, Utah, from June 30 - July 20, 2013.

Teachers receive full support and a stipend during the Summer Session. In addition, 6 quarter-credits of 400-level mathematics are available from the University of Washington.

The Math Forum hosts information on PCMI's K-12 programs here, including SSTP working sites dating back to 2001:


PoW taking place: math problem-solving moment of the week

"This challenge helped me go beyond the content in the textbook by making me think in different ways about triangle sides, square roots, and the Pythagorean theorem. I had to make decisions about how to solve the problem, about the validity of the different answers I had gotten, and on how to go about explaining how I got my answers. I investigated by asking my teacher (Ms. Winne) several questions, and I received a few small hints that planted the seed of the tall tree that I climbed to the answer. I have used the Pythagorean theorem in the past, on sites like Alcumus, but have never used it in a problem as complex as this one. It was fun and challenging at the same time. My dad has been talking to me a lot about proving the Pythagorean theorem. It is a very useful theorem and I would like to learn more about it and how to prove it."
- Ben, highlighted in the Geometry PoW's Latest Solution

Math Mistakes


Every day since last summer, New York City high school math teacher Michael Pershan has posted a photo of a math error made by a student — and invited other teachers to come analyze and discuss the misunderstandings behind those mistakes.

Now taking place: math education conversation of the day

"Can you recommend iPad apps that are good for integer review and practice? Can you point me to a place where I can find reviews of applications for middle school?"
- Sherry, posted to the middle school (grades 5-8) discussion group of the Association of Math Teachers of New York State
