Lesson Purpose
Lesson Narrative
In previous lessons, students analyzed and solved story problems.
In this lesson, students match story problems with tape diagrams and equations and write stories based on a tape diagram (MP2). The words in each story need to be interpreted carefully in order to decide which equation is the best match. For most problems, there is a choice for students to make because the problems can be represented and solved with either addition or subtraction. Likewise, tape diagrams can often be interpreted in multiple ways, either as showing addition or showing subtraction.
The lesson synthesis highlights how a tape diagram can help to students make sense of a story problem and decide on a method to solve the problem.
