What’s It Like? 

Desmos is a free graphing and teaching tool for math. In addition to plotting equations, classroom activities are available to help students learn about a variety of math concepts. For example, students can learn how to transform periodic functions by trying to slide marbles through points on a graph. Or, they can plug in their own equation and see what kind of graph pops up; sliders allow students to adjust values and see what happens. Users can also click directly on the graph to find the coordinates of points of intersection, maxima, and minima.

Price: Free

Grades: 6-12

Rating: 4/5

Pros: Free and easy-to-use tool that gives students a visual way to understand expressions.

Cons: Without significant help, less experienced students might struggle when things gets complicated.

Bottom line: Innovative calculator and simulations are a standout graphing option for inquiry-driven math.
