Lesson Plan
Solving absolute value equations
Goals / Objectives
Solve a linear absolute value equation in one variable, finding every solution or determining that there is none
Interpret $|a|$ as the distance from $a$ to zero, and explain from it why $|A| = d$ splits into exactly two cases
Determine from the isolated right side whether the equation has two, one or no solutions
Solve an absolute value equation whose right side contains a variable, rejecting candidates that fail in the original equation
Translate between $|x - c| = d$ and a distance or tolerance statement in words
Standards
"Make strategic use of algebraic structure, the properties of operations, and/or reasoning about equality to solve: • linear absolute value equations in one variable or simple rational and radical equations in one variable."
