*Discover Linear Algebra* is an open-access linear algebra textbook that uses a discovery-based approach to introduce students to this beautiful subject.
The philosophy of this treatment is to allow the undeniable core ideas and patterns of linear algebra to reveal themselves to the student.

Each chapter begins with a set of *guided-discovery* activities suitable for use as in-class group activities, as pre-class preparatory explorations, or for self-study.
The exposition in the remainder of each chapter reflects and expands upon these introductory explorations, beginning with an informal *Concepts* section, followed by a section of *Examples*, and ending with a more formal *Theory* section of theorems and proofs.
