Lesson Narrative
In a previous unit, students solved Add To, Result Unknown and Take From, Result Unknown story problems. In previous lessons, students solved Put Together, Total Unknown and Put Together/Take Apart, Both Addends Unknown story problems. In this lesson, students solve familiar types of story problems. Because the types of story problems are mixed, students need to make sense of what the story is asking them to do (MP1). Then, students create their own story problem.
This lesson has a Student Section Summary.
