Why Are Things Shaped the Way They Are?
Whiten, David J.; Whiten, Phyllis
Teaching Children Mathematics, v15 n8 p464-472 Apr 2009
This article examines important geometric concepts embedded in the shape and design of natural and manufactured objects. The Whitins first describe fourth graders exploring why manhole covers are circles. Then the authors offer a range of activities to demonstrate how inquiring about shape in botany, geology, biology, and industry can effectively integrate science and mathematics and foster a life-long spirit of inquiry. (Contains 2 tables and 9 figures.)
