Geometric Flips via the Arts

Donald Sellke 

February 1999, Volume 5, Issue 6, Page 379

Abstract:
The activities described here are designed to enhance students' spatial-reasoning ability, a neglected part of the geometry curriculum, while encouraging them to reason, problem solve, communicate, and make connections between school subjects and between geometry and the real world. These activities involve tasks which, whether done in a large-group setting, smaller cooperative groups, or individually, require students to conjecture and then verify their conjectures as they investigate reflections of objects—letters and words—from the discipline of language arts. The tasks give teachers opportunities to question, listen, and assess decision-making skills, which are all part of the NCTM's vision of effective teaching (1991).
