Mentor groups will provide feedback to submitters in upcoming problems opening on these dates:

• PreAlgPoW, February 15
• FunPoW and AlgPoW, February 22

Please have your students submit solutions. If they receive replies from a mentor, we hope you'll encourage them to revise. Not only will your students learn more, but the mentors will learn as well!

Technology Problems of the Week (tPoWs) are freely accessible problem-solving challenges modeled on our Problems of the Week that take advantage of interactive mathematics tools such as Java applets, TI-Nspire™, The Geometer's Sketchpad®, Fathom™, and spreadsheets.

We are moving the tPoWs from the old software system to a new one. You may use either system during this transitional period. The tPoWs are free, but require a login—if you have a login for the Problems of the Week or KenKen, you can use that, or sign up for a free login using the instructions on the site.

Steven Strogatz, a professor of applied mathematics at Cornell University, has just embarked on a several-week tour of mathematics from an adult perspective--from the basics of math to the baffling. This New York Times series is not meant to be remedial, but rather to give readers a better feeling for what math is all about and why it's so enthralling to those who get it.
