Solving Equations Using Balance Scale, Decomposition, and Graphing

This Solving Equations Using Balance Scale, Decomposition, and Graphing lesson plan also includes:

There's more than one way to solve an equation — three, actually. Scholars learn how to solve simple linear equations in one variable using three different methods, which include using balance scales, using decomposition (e.g., turning 2x into x + x), and using graphs.
