I love, love, love this activity!
I begin by having the students work independently. They answer 14 order of operations questions, then select one problem and create a story to go with it.
I give them roughly 20 minutes to work on their paper. After this, I split them into groups and have them compare answers, correct mistakes, and read their story to other members in their group.
At the end of class, I allow students to share their stories with the entire class. If the story fits the expression, then I give them a little extra credit on the paper. If it doesn’t, we discuss why the story is not a perfect match.
This is such a fun activity—I love hearing the kids’ creativity come out as they read their stories.
