For this unit, I modified an idea I had used with my Algebra 2 students. I taught my Algebra 2 students to shade inequalities by testing points. It was a natural way for me to teach it because that is how I remember learning. But, it failed for my students.
I modified my instruction away from testing points, and I like the end result a lot better.

A similar explanation can be used for vertical lines, but I neglected to include it on the graphic organizer that we glued in our interactive notebooks.
I surveyed my students about postponing this unit until several months after finishing our unit on linear equations. I asked them if they whether they liked the placement of this unit or if they would have preferred to have covered this when initially learning to graph linear equations. I believe the consensus of the class was that they thought it was beneficial that we waited. And, I agree. Postponing this unit allowed me time to spend an entire week on solving literal equations. This helped beef up our skills to allow us to quickly and accurately convert an equation into slope-intercept form.
