Students begin work on their unit portfolios. In the process, they begin to review the unit, reflect on specific aspects of what they have learned, and study for the unit assessments.
Students look back on their work with graphs to identify two ways in which they were used: to describe or model a problem situation and to make a decision about a problem situation.
Students work on this activity individually.

Students’ work from the entire unit
Prior to this beginning work on the unit portfolios, remind students to bring all their work from the unit to class.
Encourage students to share some of their thoughts about the period of the gold rush with the class, perhaps asking them to read portions of what they wrote.
You might also ask volunteers to identify the names of the activities, and possibly question numbers, they selected for each graph.
