Teaching Math using Desmos
I'm Geoff  a teaching assistant in the Mathematics Department at the University of Hawaii at Manoa  and I love Desmos.
Desmos is a free, online graphing calculator. If you aren't already familiar with Desmos, you can read more here, see some tutorials here, or just dive right in.
Below you'll find examples of how I've used Desmos in my Calc 1 courses over the last couple years. I hope that you will try them in your classroom, or be inspired to create Desmos lessons of your own!

PointSlope Form
It's easy to explore PointSlope form using Desmos. Here's a few ideas to get you started.

LimitS
Use tables to numerically explore limits.

Limits & Continuity
Arrows dynamically represent the relationships between limits and continuity.

Discontinuities
A graph that senses when it's near a discontinuity (except removable singularities)

EpsilonDeltA Proofs
Epsilondelta arguments are no longer so scary with the help of this Desmos graph.

Derivative Practice
Desmos can give students instant feedback on their differentiation skills.

Local Extrema
Use the First and Second Derivative Tests to identify local extrema.

Mean Value Theorem
A fairly simple demonstration of a classic calculus result.

Concavity
A visualization of the second derivative.

Newton's Method
Use derivatives and Desmos to build your own rootfinding algorithm.

Antiderivative Practice
Just like differentiation, Desmos can also give students instant feedback on their antidifferentiation skills.

Riemann Sums
A beautiful and dynamic way to present and explore integration.

Solids of Revolution
A visual aid for integration with the Disk/Washer Method or the Shell Method.

UNIFORMLY continuous
A visual aid for introducing uniform continuity.

lipschitz continuous
A visual aid for introducing Lipschitz continuity.
