When we first started following the Common Core in Algebra One this topic was eliminated! But we noticed it's back in when we examined an updated Algebra One Common Core list. Huh. I wonder if someone forgot it the first time?
FYI - I'm a big fan of emphasizing the whole "distance from zero" concept here when solving. So many students miss one of the solutions, so we start by drawing number lines to visualize this. And we check the two solutions to see how the two (often very different) values can work.
Here is the foldable document:
and some application work
