Reflection: Vertical Alignment Solving Linear Systems of Equations with Elimination (Day 1 of 3) - Section 2: Guided Notes + Practice


I find that it is important to build up to elimination by first establishing a base knowledge of zero pairs. This is especially important for students who struggle with negative integers. Most students think this is the easiest way to solve linear systems of equations, however they try to create zero pairs where they do not exist.  It is important to stress to students that only opposite numbers (-5/+5) cancel each other out. The coloring activity is great for kinesthetic and visual learners and really helps students think about what happens when you add equations and how zero pairs you can create zero pairs when they do not already exist.
