 Teacher Review (Not based on classroom experience)Reviewer: rebsterjane, Jun 10 2008 4:37PM |
Review based on: personal experience, student observations |
Appropriate for: practice of skills and understandings |
What math does one need to know to use the resource? Students need to be able to solve multi-step variable equations |
What hardware expertise does one need to learn to use the resource? Basic computer skills |
What extra things must be done to make it work? Students should be able to navigate the mouse. |
How hard was it for you to learn? Easy |
Explanation: The scales are very visual. Usually, it takes a minute for students to understand that they have to balance the equations and the you have to click on the operation sign and put in a number for each step. Once students grasp this concept they move right along with the practices. |
Ability to meet my goals: Effective |

Other Comments: I have been looking for a tool to explain clearly that an equal sign equates two quantities (not just expressions). This tool makes the quantity a weight, and the graphics clearly show how addition and subtraction changes the weight without changing the balance. Great tool. |
What math does one need to know to use the resource? Solving first order equations. |
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? Easy |
Explanation: No problems learning how to use. |

Other Comments: I really like that students move the parts onto an equation to balance the scale. Then the students go through the steps of solcing the equation by completing the same operations on both sides. The students see a visual and then work through the steps of the problem. |
What math does one need to know to use the resource? You need to know basic skills for solving equations with variables on both sides. |
What hardware expertise does one need to learn to use the resource? None. |
What extra things must be done to make it work? None. It was self-explanatory. |
How hard was it for you to learn? Very Easy |
Explanation: The resource was set up in a user friendly manner. First the pieces of the equation must be moved and the the equation must be worked out step by step to isolate "X". |
Ability to meet my goals: Effective |
