On my Mind
On My Mind: Not All Manipulatives and Models Are Created Equal

Sally Roberts 

August 2007, Volume 13, Issue 1, Page 6

Abstract:

The author of On my Mind describes the challenges a teacher faced to find the "perfect" model, and provides the reader with some insights to construct meaningful understanding of the triangle inequality theorem.  On My Mind is a regular department of Mathematics Teaching in the Middle School, in which authors have the independence to choose a topic that they feel would be helpful in sharing with readers.
