Teacher Review (Based on classroom experience) Reviewer: OklaMathman, Nov 19 2008 04:26:36:543PM 
Classroom use in Courses and Topics: Algebra: Linear Equations, Analyzing Linear Data, Linear Systems; Algebra II: Solving systems of equations 
Duration of classroom use: One Week 
What did students learn? How to come up with a linear equation and compare graphs. 
What did students do with the resource? After a little kick start from me most came up with equations pretty quickly but only the advanced students handled the extra condition correctly with the fewer allowed minutes per month plan. 
How hard was it for students to use? Ok 
Appropriate for: practice of skills and understandings, applications of a concept or technique 
What math does one need to know to use the resource? How to come up with a slope intercept equation 
What hardware expertise does one need to learn to use the resource? Any TI Graphing Calculator 
How hard was it for you to learn? Ok 
Explanation: I had no problem with the PoW. Some of my students especially those in Algebra I have had very little experience with graphing technology.

Ability to meet my goals: Effective 
Recommended for: Algebra: Linear Equations, Linear Systems; Algebra II: Solving systems of equations
