Resequencing Calculus is a project that has reordered the typical delivery of Calculus material to better serve the needs of STEM majors. Funded twice by the National Science Foundation, this project has produced a three-semester textbook that has been piloted at numerous institutions, large and small, public and private. This paper describes the Resequencing Calculus project, its history, and its future. In addition, the results of using the new curriculum and textbook at one pilot institution are presented.
