Desmos graphing trig
Extra point are given if you can collect the token. In this game, student must race the timer to write the equation of a sinusoidal function that matches the given graph. They also had to list the features of the graph including amplitude, period, and principal axis. In this activity, students worked in pairs to match the graph with the function equation and function table.

Connections could also be made to characteristics of a sine function graph such as amplitude and period. Students can trace the heights of the curve to build half a period of a sine curve. This is a nice idea to make connections between the unit circle and the graph of the sine function.

The draft of the book (link above) is free for now, but it occurred to me that you could do at least one activity (integrates trig, geometry, data, exponential functions) easily using Desmos’s cool new technology.
The idea of the book is that there are geometrical constructions that have relationships under them-usually a relationship about length-that you can model using a symbolic formula.
At a recent meeting, I got to tell people about an old, non-finished book, EGADs (Enriching Geometry and Algebra through Data).
