Today Joshua and I reviewed his work. He had difficulty with this assignment. We reworked each of the problems together, so Joshua could fill the gaps in his misunderstanding. Then we pulled problems from AP Classroom. After today, I realized that I dislike the way I first presented this concept to Joshua. Tomorrow, I am going to take a step back and re-introduce this material the way I usually teach it in Algebra 2. I think Joshua will have a better understanding of it. Then we can bring in the AP problems.
