AP Calculus Lesson: Volumes of Revolution Washer Method by Slicing Bagels

This hands-on activity builds your students' conceptual understanding of finding volumes of revolution using washer method. By slicing a bagel and computing the volume of each slice, students learn how the washer method works and what each part of the integral represents. Teaching your students with graphing software and 3-D images is helpful, but nothing beats holding a bagel, slicing it up, and finding the volumes. This is a lesson your students will remember when looking back on your calculus class.
