Data Flyer

Activity: Enter a set of data points, then derive a function to fit those points. Manipulate the function on a coordinate plane using slider bars. Learn how each constant and coefficient affects the resulting graph.

Graphit

Activity: Create graphs of functions and sets of ordered pairs on the same coordinate plane. This is like a graphing calculator with advanced viewing options.

Linear Inequalities

Activity: Students create linear inequalities and systems of linear inequalities on a coordinate plane. This is like a graphing calculator with advanced viewing options.

Multi-Function Data Flyer

Activity: Enter a set of data points and a function or multiple functions, then manipulate those functions to fit those points. Manipulate the function on a coordinate plane using slider bars. Learn how each constant and coefficient affects the resulting graph.

Multiple Linear Regression

Activity: Students compare multiple independent variables as predictors of one dependent variable. Students explore correlation and lines of best-fit.

Recursion

Activity: Graph recursive functions by defining f(0)=C and defining f(n) based on f(n-1).

Regression

Activity: Plot a bivariate data set, determine the line of best fit for their data, and then check the accuracy of your line of best fit.
