I created this writing absolute value equations and inequalities foldable for my Algebra 1 students to complete and glue in their interactive notebooks.
We completed this foldable after exploring absolute value relations and creating an absolute value foldable. Students were given graphs of various absolute value equations and inequalities, and they had to determine the original equation/inequality based solely on the graph.
I gave my students a graph of an absolute value relation. Students had to identify the slopes, vertex, and orientation. Then, we wrote the equation or inequality. I think in the past, I would have expected students to jump straight from the graph to the equation. But, I had already made a nifty slopes, vertex, and orientation table from the previous foldable.
I love how little of the work I actually had to do during this lesson. Students were offering answers. Other students were asking questions. And, more students were answering those questions. It was a beautiful!
During the 2017-2018 school year, I changed up this lesson slightly.
I had students work through this on their own or with partners (their choice) and check their work with Desmos along the way. It was a beautiful lesson to watch them make the connections we had started making with the previous lesson.
