Lesson Plan 2: Cups and Chips - Solving Linear Equations Using Manipulatives
In this lesson, students use manipulatives to represent visually the steps they take to obtain a solution to an algebraic equation. They develop an understanding of the connections between the solution involving manipulatives and the symbolic solution.
One 50-minute class period
Students will be able to:
Use manipulatives to solve linear equations of the form ax + b = c, where a, b, and c are constants.
Use symbolic methods to solve linear equations.
Verify and check the solutions to the equations by using substitution.
