Appropriate for:
introduction to a concept, practice of skills and understandings, applications of a concept or technique
What math does one need to know to use the resource?
arithmetic, some algebra, line functions (helps to understand graph)
What hardware expertise does one need to learn to use the resource?
Very little. As long as you can click and drag the mouse.
How hard was it for you to learn?
Very Easy
Explanation:
The tool is set up so that the user can click and drag the drag-bars to a specific number. It is also very easy to read and understand the results. I also like how it shows the equation at the bottom of the tool.
Ability to meet my goals:
Effective
Recommended for:

Math 7: Equations and functions, Ratio and proportion
Geometry: Points and lines
Algebra: Use of Variables, Linear Equations
