Exploring & Writing Geometry
Sanders, Cathleen V.
Mathematics Teacher, v102 n6 p432-439 Feb 2009
When given opportunities to explore mathematics, make conjectures, and write about what they have discovered, students gain a deeper understanding of this fascinating subject. In this article, the author describes her successful Geometry Portfolio class. In addition to traditional student work, the author frequently added short essay questions or extended problems in which students were expected to show their work in a clear and comprehensible manner. Her students also did a number of writing-intensive projects throughout the school year. She discovered that her students rose to the challenges; their enthusiasm was exciting to see, and their responses were fascinating. Some of their projects and responses are presented in this article. (Contains 7 figures.)
