What Else Can You Do with an Open Box?

Catherine Miller, Douglas Shaw 

March 2007, Volume 100, Issue 7, Page 470

Abstract:
Starting with the classic Open Box problem, we present extensions of this problem that can be used in high school mathematics classes. We also challenge high school teachers to use this process of problem analysis in their own practice as a way to enrich the content of their lessons and as a means of individualized professional development.
