This Instructional Activity is a part of the Lesson 5, Unit 3, Grade 6. At first glance, students may look only at the number of cans in each offer or only at the price. Let students know that they need to consider the price per one can. If any students used a representation like a double number line or table to support their reasoning, select these students to share their strategy first. Keep these representations visible. Follow with explanations from students who used more efficient strategies, and use the representations to make connections to more efficient strategies.
