The lesson begins with a review of the foundational pieces of the lesson from the pre-assessment students did the day before: verbally describing and putting information into a table to determine when three plans for DVD rentals would cost the same amount. Students are then asked to state how they got started on their individual tables. After they share their strategies with their shoulder partners, students are given the objective of the day’s lesson. The focus of the lesson is to look at some different tabular representations. They are going to analyze each one to see if they can determine when the three different DVD plans cost the same, and they will look for similarities and differences between the tables. The order of the student work is purposeful. To make the lesson accessible to all students, the teacher chose student work that built upon the previous student to unfold a purposeful progression to tell the mathematical story about cost analysis.
