Since they pretty much were ok with basic equations, we skimmed it and jumped right in to more difficult equations. These foldables I got from Sarah at Math=Love.
I really liked the multi-step equations foldable. It was pretty straight forward and easy to follow. If my students got stuck, I'd have them go look at this foldable and tell me what all they've checked for and what they need to do next. Eventually they quit asking.
Absolute value equations came next. What I used isn't a foldable, but I think this was pretty effective.
