Teacher Review (Not based on classroom experience) Reviewer: WandaB, Dec 4 2004 03:54:22:853PM |

Review based on: personal experience, student observations |

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

Other Comments: This applet encourages students to think 'outside the box' to discover how many squares are actually on a checker board and challenges them to find the pattern. |

What math does one need to know to use the resource? Students need to understand patterns and squaring a number. |

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

What extra things must be done to make it work? The suggestion to have students actually cut their own squares out of grid paper to physically determine how many squares would be very beneficial. |

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

Explanation: I found the applet very easy to understand and manipulate. As a teacher, I would extend it further to have students write the function rule for the pattern. This would be a great exercise for helping them understand the difference between linear and quadratic functions. |

Ability to meet my goals: Very Effective |
