Balance-Solving for Unknowns, Part Three

This Sketchpad activity, which opens on Geometer's Sketchpad as well as on iOS with Sketchbook Explorer (cataloged separately), is the third of three balance activities in which students develop intuitive strategies for writing and solving algebraic equations. In this final activity, users must simplify algebraic equations by removing identical shapes from both sides of a scale. A five-minute movie provides detailed instructions and downloadable PDF of teacher notes and student worksheets are also included.
