Reflection: Adjustments to Practice Solving Absolute Value Equations and Inequalities (Day 1 of 2) - Section 1: Introduction

 

I have been searching for ways over the last few years to improve student achievement on solving Absolute Value Equations and Inequalities.  I felt like I was teaching the students more on how to set up the problem by memory than from a conceptual understanding.  I would teach the lesson, but come test time at the end of the year, students tested low in these areas.  Students also tested low on inequalities.  

So my goal in this Unit, and in this lesson was for students to develop a deeper understanding of inequalities, as well as Absolute Value Inequalities.  I modeled the following different ways to solve Absolute Value Inequalities:

  • distance from zero
  • graphing on a coordinate plane
  • rewriting as compound inequalities

I think that these methods will provide my students a stronger sense of Absolute Value, and how to solve Absolute Value problems.
