Other Comments: This would be good to introduce or practice Area & Perimeter if physical manipulatives are not available. But is has the ability to have the student create their own shape. By giving students a particular perimeter or area, they would be required to find a correct shape. The webiste also gives immediate feedback to student on whether they are right or not and hte ability to try again. I also liked the ability to keep score and to keep a table of shapes. |

What math does one need to know to use the resource? basic knowledge of area and perimeter |

What hardware expertise does one need to learn to use the resource? how to use a mouse |

What extra things must be done to make it work? none |

How hard was it for you to learn? Easy |

Explanation: I had to figure out to get rid of a square, required me to re-click which can be cumbersome. |

Ability to meet my goals: Very Effective |

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

Other Comments: Obvious applications are finding perimeter and area practice for rectangles and other shapes. The ability to draw your own shape and compare area and perimeter permit possible advanced investigations. |

What math does one need to know to use the resource? counting, basic definition of area and perimeter |

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

What extra things must be done to make it work? none |

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

Explanation: The shapes are drawn by the program on a grid. You enter area and perimeter. It is possible to draw your own shapes, keep score and compare area to perimeter for many shapes. |

Ability to meet my goals: Very Effective |

Other Comments: It is a great way to introduce area and perimeter! Students can start with rectangular shapes to compare area and to find the formula. They can extend their learning into irregular shapes and see how when the areas are the same that the perimeter can be different. |

What math does one need to know to use the resource? You should understand the difference between area and perimeter and how to do basic calculations to find area and perimeter. |

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

What extra things must be done to make it work? Essential questions given by the teacher can make this an application lesson. Asking questions to engage students to look for what happens to the perimeter when the area stays the same can take this beyond basic understanding. |

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

Explanation: Younger children could explore this and find answers to the smaller rectangular shapes. |

Ability to meet my goals: Effective |
