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.

Equation Solver

Activity: This activity helps you understand how to balance an equation. You input the term and the operation. The activity uses that term and operates on both sides of the equation. It then displays the resulting equation. Equation Solver is one of the Interactivate assessment explorers.

Graph Sketcher

Activity: Students can create graphs of functions entered as algebraic expressions -- similar to a graphing calculator.

Recursion

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