In previous lessons, students solved different problem types within 100. Students made sense of story problems and connected story problems to diagrams and equations. The activities in this lesson can be used to assess the methods students use to make sense of and solve story problems on their own. Students are introduced to the idea that story problems could have more than one step. 

In the first activity, students solve a Put Together/Take Apart, Total Unknown problem and then use their solution to solve an Add to, Result Unknown problem. In the second activity, students work together to make sense of and solve a two-step story problem where both parts are presented together.

This lesson has a Student Section Summary.

Think about times when students were able to make connections to and build on the ideas of their peers during discussions today. What norms or routines allowed students to engage with other students’ ideas?
