Lin McMullen is a former high school calculus teacher who has fifteen years of experience working with high school calculus teachers to help them improve their craft. McMullen has also created this resource website for calculus teachers and students alike. Teaching Calculus can be browsed in a number of ways. Those who are currently teaching or taking a Calculus class can explore Thru the Year, which organizes calculus resources in the order in which they are typically taught in American high schools. For example, visitors will find resources related to Theorems, Definitions, and Logic in August followed by Computing Derivatives in September. Resources include study guides, definitions of key terms, classroom activities, and instructional videos. These videos are also available for browsing in the Video section of the website. Collectively the Thru the Year and Video section provide useful resources for instructors to incorporate into their classroom or for students to use while working on homework. In addition, instructors can find a variety of PowerPoint presentations and handouts in the Resources section.
