Desmos Models
Tip for teachers: The key is to teach students how to build these models on their own. In doing so they learn the language of mathematics. It is less important for students to manipulate the predeveloped tools below (although in their play, they develop number and mathematical sense). Use these as models of what can be done in the classroom.
 Exponential Growth and Decay
 Simple Pendulum Function
 Calculus Introduction Demo
 Regular Polygon Function of Interior Angles
 Summation Squares
 Pythagorean Theorem
 Calculating Pi with Perimeter of a Regular Polygon
 Transforming Sinusoidal Functions
 Transforming Functions
 Quadratic Function Model

EVERYONE can learn math to the highest levelsSine, Cosine, Tangent Comparison
MISTAKES are valuable
QUESTIONS are really important
Math is about CREATIVITY and making SENSE
Math is about CONNECTIONS and COMMUNICATION
Math class is about LEARNING not performing
DEPTH is more important than speed
