Abstract
This lesson is the first in a series that examines mobility and cascading. Students explore these concepts in the context of biographical stories of real people that involve significant ups and downs in economic status, social position, and health. Then, using an interactive infographic that shows income mobility, students consider unequal patterns in mobility. The lesson aims to show students that social position is more than a snapshot in time. Instead, we can think about strings of events and how policies can play a role in the ups and downs of a life.
