Secondary Level Problems of the Week

Annie Fetter annie@mathforum.org

Problems of the Week- http://mathforum.org/pow/The Problems of the Week are designed to challenge students with non-routine problems and to encourage them to clearly communicate their solutions. There are Elementary, Middle School, Algebra, Geometry, Trigonometry & Calculus, and Discrete Mathematics Problems of the Week. The Problem of the week is a mentored environment in which students submit solutions to a math challenge. Each submission is responded to by a mentor.

Problem ScheduleThe schedule for each problem includes a preview period, 8 days for student submissions, 3 additional days for revisions, a posting of sample solutions, and the complete solution archive. There is a link on the bottom of each main problem page to the calendar for that specific problem.

Archive of Past ProblemsIn the archives you will find a wealth of problems. For each problem there are highlighted student solutions which show different approaches for solving the problem. Comments from the lead mentors or problem administrator highlight student solutions that illustrate different methods of solving the problem, and discuss common errors made by students. The archive can be searched to find problems with a specific content.

## The Current Geometry POW: Area of a Rectangle - posted March 20, 2000

ABCD is a rectangle. Find the area of ABCD, and be sure to explain how you did it!

If you're feeling really creative, you might try to find two completely separate ways of solving this problem, and we might give you bonus credit.
