2010 Mathematics Game (25 December 2009)
Write expressions for each of the counting numbers 1 through 100, using the digits in the year 2010, standard operations, and grouping symbols. You may use the digits in any order, but the order 2, 0, 1, 0 is preferred. This year we will also allow the use of decimal points and double-digit numbers. This puzzle is appropriate for students in grades 3-12 with a general knowledge of mathematics.

Students may use the Web form to submit solutions starting January 1, 2010; revisit the site after February 1, 2010, to see the first solutions.

KenKen® at the Math Forum (11 December 2009)
The Math Forum is excited to partner with Nextoy® to offer a collection of KenKen puzzles. KenKen is a number puzzle related to Sudoku, but even more mathematical. We have puzzles ranging in size from 3x3 to 9x9, at four difficulty levels, with many combinations of arithmetic operations.

KenKen puzzles offer great opportunities:

  • to practice arithmetic skills in new and interesting ways
  • to learn and get better at problem-solving strategies
  • to work on organizing and communicating mathematical ideas

KenKen puzzles are free with registration. If you're already a Math Forum PoW member, you already have access to KenKen puzzles--just use your PoW login information where prompted.

Each puzzle comes with a printer-friendly view, an interface for submitting your work, and a solution viewable by teachers. Teachers with class accounts may further view the work their students submit when solving KenKen puzzles.

We allow uploads in answer submissions, which makes it much easier to show KenKen work (or even steps, moments of reflection, etc.). And we offer a table-making tool in the explanation box, for an alternate method of displaying similar information.

The site includes:

  • Introduction to KenKen
  • Lesson Plans
  • Rules
  • Discussion
  • Tutorial

The Math Forum @ Drexel at CMC-North (27 November 2009)
Coming to Asilomar December 4-6 for the California Mathematics Council's northern meeting? Suzanne Alejandre, Math Forum Director of Professional Development, will present a session on Saturday:

The Math Forum @ Drexel: Learning Math Together
Learn about and discuss activities designed to help students develop and deepen their use of mathematical problem-solving and communication. Help students connect to their own way of thinking, build their ideas and experiences, and develop confidence in problem-solving. Become familiar with our activities including, Forget the Question, Try It, In Your Own Words, and PoW IQ, that each can be used with any curriculum to help students approach problem solving from a wide variety of angles!

Session 262
9:30 - 10:30 Saturday
Pacific Grove High School, Room B3

IAS/PCMI Applications and Information, Summer 2010 (20 November 2009)
The 2010 Summer Session of the IAS/Park City Mathematics Institute will be held in Park City, Utah, from June 27–July 17, 2010.This three-week residential program is organized into seven groups:

  • Clay Senior Scholars in Residence
  • Graduate Summer School
  • International Seminar in Mathematics Education
  • Research Program in Mathematics
  • Secondary School Teachers Program
  • Undergraduate Faculty Program
  • Undergraduate Summer School

These groups meet simultaneously, pursuing both individual courses of study and a meaningful amount of interaction. The rich mathematical experience combined with interaction among all participants results in greatly increased understanding and awareness of the issues confronting mathematics and mathematics education today.

The research topic for 2010 is "Image Processing" and the education topic is "Making Mathematical Connections."

Teachers are given 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 for a nominal fee.

http://pcmi.ias.edu/program-sstp/

Learn more about the Secondary School Teachers Program by viewing the information posted from previous years on the PCMI@MathForum site:

http://mathforum.org/pcmi/hstp/

Deadline for submission of applications is January 31, 2010. The IAS/Park City Mathematics Institute is an outreach program of the School of Mathematics at the Institute for Advanced Study (IAS) in Princeton, New Jersey.
