Function Machine

General Coordinates Game

Graph Sketcher - graphing calculator

Graphit - graphing calculator

Linear Function Machine

Maze Game - graphing ordered pairs

Number Cruncher- similar to function machine but more advanced

Positive Linear Function Machine- investigate linear functions with positive slopes by trying to guess the slope and intercept from inputs and outputs

Possible or Not- determine if graph is a function using vertical line test

Slope Slider- allows the manipulation of a linear function of the form f(x)=mx+b and encourages the user to explore the relationship between slope and intercept in the cartesian coordinate system

Vertical Line Test-connect points in the plane to build a function
