Activity narrative
In this activity, students revisit familiar contexts they represented with discrete diagrams in previous lessons.
Here, they see how double number line diagrams are helpful for answering more questions about these situations.
Monitor for students who use a discrete diagram and for students who use a double number line diagram.
Use this monitoring sheet to anticipate and track the approaches students use and to select which students you will call on to share their strategy during the activity synthesis.
