Exploring the Unknown: Writing and Solving Equations

Students develop methods for writing and solving equations and manipulating algebraic expressions using the hands-on equipment “Algebra Lab Gear.” Students are first introduced to Lab Gear as a tool for modeling and understanding algebraic ideas. They then learn different ways to model, combine and simplify various algebraic expressions using Lab Gear. Finally, they develop Lab Gear rules for solving equations. Eventually, most students wean themselves from Lab Gear and work strictly symbolically.
