Middle School Math Problem of the Day


Mathematics is not a spectator sport. Like any sport, the best way to get good at it is to play it all the time, and sometimes against especially challenging opponents. This website is designed to present an opportunity for this kind of practice and challenge.

Beginning,Monday September 17 and on (almost) every school day throughout the year, I'll be posting a mathematical "problem of the day" at this site. Since I live in Philadelphia, I'll be following the Philly School District calendar, which can be found here.

The problems will be suitable for middle school students (7th-8th grade), although many will be accessible to 5th and 6th graders, and some might prove challenging even to high school students.

The problems will range over arithmetic, pre-algebra and algebra, basic geometry, strategy, probability and other areas of mathematics. The main thing is that many of the problems will seem difficult at first glance, but most of them can be approached by "playing around" with the numbers, making educated guesses, or just patient thought.

If you are a teacher who is interested in using some or all of these with your students, please send me an email at

deturck@math.upenn.edu

I will be happy to send you advance copies of the problems (with hints and solutions) so that you can plan and coordinate these problems with what you are doing in class. I'm also interested in receiving feedback about the problems and the site, so feel free to email to let me know what you think.
