As our project has grown, we have learned that successfully using our materials depends on more than just the books. Much of what has made our approach successful has come from observing our students and the various ways in which they may approach a problem. These insights, along with solutions to selected problems and possible extensions have been included in a teacher’s edition for each book. These editions are only available for instructors so to support faculty who use our materials we have created a faculty login. Faculty members may request a free account to access the teacher edition for each book. Our account request form can be found at http://artofmathematics.org/account-request-form. A member of the Art of Mathematics team will review the application and respond shortly thereafter.
