Manipulative Calculus is a project at Harvard University in which we are constructing 3D models and manipulatives to be used in active learning lessons in our calculus course sequence.

Since Fall 2018, our models and lessons have been incorporated into Math 21a, Multivariable Calculus, at Harvard. In Fall 2019, we added models and lessons for Math 1b, Integral Calculus. For sample lessons and instructor reflections, please visit Lessons.
