Teacher Review (Not based on classroom experience) Reviewer: KimE, Jun 29 2009 02:50:25:850PM |

Review based on: personal experience |

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

Other Comments: This activity can have a variety of extensions that fit naturally into the format. Students can begin a unit of study on Algebra to explore balance. As the lesson extends, the teacher can facilitate understanding of what "equal" means. Students can then begin to assign digits to the shapes to make equations. |

What math does one need to know to use the resource? To explore only, students need to understand that to balance both sides must "weigh" the same. To extend the learning they must understand that the fulcrum is the equals sign. Learning can continue into equations by assigning number values to each shape. Students must then understand basic computation and that equations exist on both sides of the equals signs. |

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

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

Explanation: Even young children could free explore with this applet. The program allows exploration until a "balance" is found. |

Ability to meet my goals: Effective |

Recommended for: Math 4: Algebra; Math 5: Algebra and expressions; Math 6: Algebra and expressions |
