A Visit to Your School

Observing mathematics is a lifelong enterprise. Mathematics exists all around--from one's own backyards to the many exciting places in the world. Nature exhibits some imperfect geometry that one may not see in textbooks, but it is real mathematics and part of people's everyday lives. Nature provides a meaningful context for the knowledge and understanding that one expects students to gain by studying mathematics. Here, Bunten et al present a problem that involves measuring circles, estimating, and making some connections to nature.
