Review based on: I discovered the tool through a university class. I was technically "forced" to use it in order to complete classwork. |

Appropriate for: introduction to a concept, practice of skills and understandings, applications of a concept or technique |

What math does one need to know to use the resource? arithmetic, some algebra, line functions (helps to understand graph) |

What hardware expertise does one need to learn to use the resource? Very little. As long as you can click and drag the mouse. |

How hard was it for you to learn? Very Easy |

Explanation: The tool is set up so that the user can click and drag the drag-bars to a specific number. It is also very easy to read and understand the results. I also like how it shows the equation at the bottom of the tool. |

Ability to meet my goals: Effective |

Recommended for: Math 7: Equations and functions, Ratio and proportion Geometry: Points and lines Algebra: Use of Variables, Linear Equations |

Tool: Changing Cost per Minute Reviews
