We have designed and classroom tested many activities that you can use along with this textbook. In order not to give away the things that students are expected to discover during these activities, each activity appears in the book only as a prompt that self-study students or students who must miss a class can use on their own to mimic the experience of the in-class activity. In the subsequent section of the book is a short summary of the things we would hope a student would learn from the activity, but not a solution to the activity.
