This year, I decided to remedy this by putting an obnoxiously large plus or minus sign in their notebook. We took the notes on top of the plus or minus sign. These are the same plus or minus signs that I used last year for graphing different types of slope in Algebra 1. I love finding new uses for files I've already created!

I wish I could say that this method was fool-proof. I wish I could say that my students never forgot the plus or minus sign in front of their answer. But, then, I'd be lying to you. I do think that this visual helped some of my students, though.
Here's the two-page spread in our interactive notebooks. I have yet to blog about the Zero-Product Property and Solving Quadratics by Factoring yet. They're coming, though. I promise. Pinkie promise.
