Identifies characteristics of mathematically maturity at the calculus level and provides a project focusing on implicit differentiation that is designed to build students' mathematical maturity by helping them connect calculus concepts with prerequisite material. Gives prelesson assignment and lesson outline with examples of student responses that indicate weak understanding of problems and their probable reasoning. Solutions are included.

The proportional nature of geometric work, and the ways in which proportional reasoning can be employed as a generalized problem-solving tool. A geometric construction is presented for students to solve. The author gives reasoning via proof and proportions and provides extension activities.
