NLVM Algebra – Algebra Balance Scales

General Observations:

Algebra Balance Scales

Is very easy to use Covers single variable algebra equations Gives ability to input your own equation Gives ability to use addition, subtraction, multiplication, and division to solve problems Visually shows what is on each “side” of the equation Uses a balance to symbolize both sides of the equal sign in an equation

Thematic Observations:

The algebra balance scales simulation would be easily integrated in a developmental math course. It would serve as a great topic review tool and homework assistance tool during the solving equations unit of the course. The simulation also includes an option to download the application to run on a computer without Internet access.
