The purpose of this activity is for students to solve their story problems and represent one or more ways to solve the problem (MP2). As students work, encourage them to find a different way to solve the problem or a different way to represent the problem once they have completed a solution.

• “In the next activity, you are going to look at the posters and leave comments.”
• “What are some things that you will look for when you look at the posters?” (Do I understand the story? Do I agree with the solution? Can I follow the thinking or reasoning?)
• “What are some different ways you can show solutions to the problems?” (drawings of objects, base-ten drawings, diagrams, number lines, expressions, equations)
• “Keep an eye out for all of these representations and think about which ones you would choose if you were solving the problem.”

The purpose of this activity is for students to see the different story problem posters their classmates made. After the Gallery Walk, students have a chance to make revisions to their own posters. This could be making corrections, but it could also be adding new details or different representations based on what they learned from seeing the other posters. Some students might need guidance with asking mathematical questions or leaving feedback using precise math language (MP3, MP6).

Consider asking or displaying:

• “What is something you read or saw that helped you understand the story problem?”
• “What is something the writer could add or change to help make the problem more clear?”
• “What is something you saw that made it clear how the problem was solved?”
• “What is something that could be added or changed to make the writer’s method more clear?”
• “What questions do you have about the story problem or the solution?”

The goal of the Activity Synthesis is to reflect on how the posters were the same and how they were different.

• “What did you change on your poster after seeing the other posters?”
• “If you had time, what other changes or additions would you make?”
