problem_activity: Narrative
The purpose of this activity is for students to create a poster of their story problem so that others can solve it. Students use these posters in the next activity, in which they solve, and write equations for other students’ story problems. They notice connections between the equation and the written problem and create a poster that communicates their work.
Alternatively, to make this task more challenging, students can rewrite their stories as missing addend story problems.
Required Materials
Materials to Gather
Tools for creating a visual display
Launch
Groups of 2
Give each group tools for creating a visual display.
“Now we’re going to use your story problems from the last activity to make posters so we can show our thinking and challenge each other.”
Activity
“Choose one of the story problems you and your partner wrote. Create a poster with your story problem. Your classmates will solve it in the next activity. So make sure to not include the answer.”
5 minutes: partner work time.
“Take turns sharing your poster with another pair at your table.”
“The pair listening should tell the presenters if their poster is clear and organized.”
5 minutes: group work time.
If needed, give students an opportunity to revise their posters.

Activity Synthesis
“What were some things you changed to make your poster clear and organized for the gallery walk?” (We wrote the story problem bigger. We added a picture to go with my story.)
