Lesson Plan Solving Systems Using Matrices

In this fifth lesson of the Systems of Equations Unit, students will learn how to solve systems of equations using matrices. Matrices provide an efficient way to organize and manipulate systems of equations, particularly for larger systems.

Students will:

• Understand how to represent a system of equations as a matrix
• Learn matrix operations such as row reduction and Gaussian elimination
• Use the inverse of a matrix to solve systems of equations
• Apply matrix methods to solve real-world problems involving systems
• Compare matrix methods to other solving techniques such as substitution and elimination

Designed for Algebra 2 and Pre-Calculus students, this lesson aligns with Common Core standards and introduces students to a powerful algebraic tool used in higher-level mathematics. Understanding matrices is essential for advanced topics in linear algebra, engineering, and computer science.

This is the fifth lesson in an eight-part unit on systems of equations. Upcoming lessons will explore additional solving techniques and their applications.
