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.

Time Allotment:
One 50-minute class period

Subject Matter:
Linear equations

Learning Objectives:
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.
