Tool: Function Machine [National Library of Virtual Manipulatives]
This virtual manipulative is designed to teach the concept of a function. It does so by allowing you experiment with various functions.
Tool: The Maze Game [Shodor's Project Interactivate]
This activity allows the user to practice their point plotting skills by having them move a robot through a mine field to a target location.
Tool: Cutouts, Nets [Freudenthal Institute]
