Sharing Teaching Ideas: Why Not Three Dimensions?

Steve Lege 

October 1999, Volume 92, Issue 7, Page 560

Abstract:
Students' skill in working with three-dimensional situations can be enhanced through hands-on model building. We hope that all students develop these skills, yet the skills are often ignored or underutilized by the current textbook curriculum. These projects also give the students alternative methods of demonstrating their mathematical power and give instructors new windows through which they can assess the level of student understanding of concepts being studied. Also includes "Chipping Away at Proofs: A Cooperative Approach" by Mark Fidler.
