Teaching Absolute Value Meaningfully
Wade, Angela
Mathematics Teacher, v106 n3 p192-196, 198 Oct 2012
What is the meaning of absolute value? And why do teachers teach students how to solve absolute value equations? Absolute value is a concept introduced in first-year algebra and then reinforced in later courses. Various authors have suggested instructional methods for teaching absolute value to high school students (Wei 2005; Stallings-Roberts 1991; Friedlander and Hadas 1988), but this article focuses on an investigation that will help students make meaning of the absolute value equation in the context of a practical situation. It connects absolute value to the concepts of rate, time, distance, and slope. (Contains 6 figures.)
