Teacher Review (Not based on classroom experience) Reviewer: fransdottr, Jun 3 2006 10:15:46:567AM |

Review based on: personal experience |

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

Other Comments: Great for California standards, 4th grade and up. Will hold student interest in seeing relationships between x and y, constants and coefficients, positive and negative slope. |

What math does one need to know to use the resource? Function tables, coordinate graphing, equation solving |

What hardware expertise does one need to learn to use the resource? none |

What extra things must be done to make it work? nothing |

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

Explanation: It would be very easy for students to work by trial and error (which would be sufficient at 4th and maybe 5th), but much more valuable for the teacher to support students by helping them formalize their generalizations. |

Ability to meet my goals: Effective |

Recommended for: Math 5: Algebra and expressions, Equations and functions; Math 6: Algebra and expressions, Equations and functions; Math 7: Algebra and expressions, Equations and functions, Linear relationships, Geometry in the plane; Algebra: One Variable Equations, Functions / Relations, Linear Equations, Analyzing Linear Data |
