Piecing It Together

This lesson builds on Lesson 8 where students learned when a single linear model is or is not appropriate to model data. The purpose of this lesson is to model with piecewise linear functions (MP4). Students analyze different real-world data sets presented as graphs. The focus of this lesson is not necessarily to find equations for the piecewise linear functions (though students may choose to do so), but rather, to analyze graphs qualitatively and to compute and compare rates of change.
