Description: 
This program introduces students to fundamental concepts in algebra. Using two or three weighing scales, students must determine the weight of a specific object or group of objects. The program provides three levels of challenge. In the first and second levels, the weighing scales model simultaneous equations such as 5x = 20 and 3x + 4y = 32. Students are solving for the variable, y. In the third level, three simultaneous equations are presented. An example would be 2x + y = 10, 2x + 4y = 22, and 3y + 2z = 26. Using objects in place of variables makes this activity accessible to students as early as fourth grade.

Comment:  It is an excellent resource. It's fun, has great graphics and developes algebraic thinking. I'll definitely use it with my students.

Comment:  Students can begin by problem solving and end by writing the equations and solving for the variables. A great bridge.

Comment:  My students would do this activity all day if they could. They love this kind of reasoning.

Comment:  Loved it! This will be great to use on a SmartBoard! 

VickiLou 
Comment:  I love Math Playground. Great applet; and they referenced a great resource as their inspiration: the Groundworks series. Access to a SmartBoard can definitely enhance this even further
