This article presents an example of how middle school teachers can lay a foundation for calculus. Although many middle school activities connect directly to calculus concepts, the authors have decided to look in depth at only one: the concept of change. They will show how teachers can lead their students to see and appreciate the calculus connection. Using this concept as a guide, teachers can develop other foundations. Demonstrating a calculus connection in middle school may motivate students to undertake increasingly advanced high school and college math. (Contains 2 figures and 1 table.)
