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.

• “En la siguiente actividad, van a ver los pósteres y a dejar comentarios” // “In the next activity, you are going to look at the posters and leave comments.”
• “¿En qué cosas se van a fijar cuando vean los pósteres?” // “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?)
• “Mencionen varias maneras en las que se pueden mostrar las soluciones de los problemas” // “What are some different ways you can show solutions to the problems?” (drawings of objects, base-ten drawings, diagrams, number lines, expressions, equations)
• “Préstenle atención a todas estas representaciones y piensen en cuáles escogerían si estuvieran resolviendo el problema” // “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:

• “Mencionen algo que hayan leído o visto que les haya ayudado a entender el problema-historia” // “What is something you read or saw that helped you understand the story problem?”
• “Mencionen algo que el autor del póster podría agregar o cambiar para hacer que el problema sea más claro” // “What is something the writer could add or change to help make the problem more clear?”
• “Mencionen algo que hayan visto que ayudó a aclarar cómo se resolvió el problema” // “What is something you saw that made it clear how the problem was solved?”
• “Mencionen algo que se puede agregar o cambiar para que el método del autor del póster sea más claro” // “What is something that could be added or changed to make the writer’s method more clear?”
• “¿Qué preguntas tienen sobre el problema-historia o la solución?” // “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.

• “¿Qué cambiaron en su póster después de ver los otros pósteres?” // “What did you change on your poster after seeing the other posters?”
• “Si les queda tiempo, ¿qué otros cambios le harían o qué le agregarían al póster?” // “If you had time, what other changes or additions would you make?”
