Classroom Exercises

These exercises were developed in CAST workshops from 2006-2011 by teachers in western Pennsylvania. Most include a lesson plan and accompanying models.  

The models are bundled into  .zip files.  Once you have downloaded a project, use the unzip program to extract the individual files.

All of these exercises are geared to high school students.
