What happens when we give students solutions and engage them in an activity where the focus is shifted from solving a problem to reflecting on methods used by others to solve the problem? We'll experience this and discuss how to create similar activities from different resources. Activities that offer a variety of problem-solving strategies provide the scaffolding for students to develop how they make sense of problems, develop additional problem-solving methods, & persevere in solving problems.

- In this activity, the focus is shifted from solving the problem to reflecting on methods used by others to solve the problem. Students are asked to embrace one of the methods, make sense of it, and present it as a reasonable method to use in solving the problem. In addition, students are asked to compare the method to a method they would have used. How does it compare? What are the advantages of each method? What are the challenges?
