The Macalester College Problem of the Week (MacPOW) is a tradition that began in 1968 as a fun, challenging activity for freshmen college students. It continues to this day (hosted by the well known Math Forum site), and about 200 problems are archived on this Web site (out of nearly 1,000 total). All of the unique conundrums are mathematically oriented, and most are word problems that require visualization and critical thinking skills. There is a mailing list to which users can subscribe and receive solutions to each problem at the end of the week. However, because MacPOW is maintained by a professor who regularly uses these problems in class, solutions only remain on the site for the duration of each semester.
