Interpret graphs showing changes over time in the percentage of foreign-born US residents and in annual deportations in this interactive from KQED. In the accompanying classroom activity, students use the interactive and look at how rates have changed over the decades. They also extrapolate to future years. To get the most from this lesson, students should be comfortable interpreting slope as rate of change over time. They should also be able to find the equation of a line when given two points.
