Linear Algebra Activities
free for use or modification in your classroom
The linear algebra activities below are designed for an introductory linear algebra class with a computation emphasis, whose only prerequisite is college algebra. These activities were developed through the support of NSF Award #1742304.
The Geometry of row operations
Topics covered: Elementary row operations
Outcomes: Students will investigate the geometry of linear systems and how row operations effect a linear system.
Balancing chemical equations
Topics covered: Vector equations, solving systems using elementary row operations, and parameterized solution sets
Outcomes: Students will practice solving linear systems using elementary row operations, as well as converting between vector equations, matrix equations, and augmented matrices. Additionally, students will learn how to find particular solutions to a system from parameterized solution sets.
How does GPS work?
Topics covered: Solving systems of linear equations using a calculator
Outcomes: Students will learn how solving a system of linear equations can help identify their location. Students will practice how to use their calculators to solve more complicated systems of equations.
Analyzing traffic flow
Topics covered: Solving systems of linear equations
Outcomes: Students will learn how to solve a linear system and interpret its results.

Topics covered: Matrix multiplication, transposition, and inverses
Outcomes: Students will learn how to use matrix operations to find a best fit curve.
Finding equations of lines and planes with determinants
Topics covered: Determinants
Outcomes: Students will learn how to use determinants to find the equation of a line through two distinct points or the equation of a plan through three noncollinear points.
Fibonacci numbers and Binet's formula
Topics covered: Matrix multiplication and diagonalization
Outcomes: Students will develop Binet's formula by using matrix multiplication and diagonalization.
Genetic inheritance with eigenvalues and eigenvectors
Topics covered: Eigenvalues and eigenvectors
Outcomes: Students will use eigenvaluces and eigenvectors to predict long term characteristic development in a species.
