The purpose of this lesson is for students to analyze a tape diagram and number line diagram and determine, in context, a question that could be answered based on each representation.

In previous lessons, students sorted and solved a variety of story problems. In this lesson, students use given information to ask math questions and figure out what question was asked when presented with student work. Students interpret the context of a story and analyze tape diagrams to determine what question is being asked (MP2, MP4). Students then pose a math question and use a representation of their choice to answer it.

In grade 3, students will continue to see and use tape diagrams and number line diagrams. How can you support their understanding of these diagrams and help them choose representations that make sense to them?
