Interactive Calculus Simulations

27 free simulations covering limits, derivatives, integrals, and applications. Each one lets you manipulate graphs, test your understanding, and get instant feedback -- no login, no cost, no installation.

For Students

Every simulation has three modes. Explore lets you experiment freely with graphs, sliders, and layers. Guided walks you through the key ideas step by step. Prove It tests whether you can do the full analysis on your own and gives you a completion code when you finish.

Start with Tool 1 (The Calculus Lens) and work through in order, or jump to whatever topic you are studying right now. Each tool card below tells you what it covers.

For Instructors

Assign any simulation as homework or in-class practice. Students earn a six-character completion code after finishing the Prove It challenge in each tool -- collect those codes through your LMS to verify completion.

Open the Pacing Guide below for a 16-week course map, or the For Instructors section for grading suggestions and a code verification tool.

Quick start: Scroll down to the Tool Library, open a section, and click Launch on any simulation. Your progress, XP, and streak are saved in your browser automatically.
