I am a mathematics professor at Linfield University. I am interested in writing student-centered, free, activity-based materials.

## Introduction to Game Theory: a Discovery Approach

This text provides an introduction to economic game theory.

Prerequisites: It does not require any college-level mathematics prequisites. A familiarity with high school Algebra is sufficient

Suggested course use: This material is appropriate for a quantitative reasoning course, a high school topics course, or any introduction to game theory course.

## Discrete Mathematics: an Active Approach to Mathematical Reasoning

This text provides a first course in discrete math, with an emphasis on proof-writing.

Prerequisites: Calculus I is helpful, but not fundamental.

Suggested course use: This material is appropriate for a standard one semester discrete math course for math and computer science students. It could also be used for a proof-writing bridge course.

## Introduction to Proofs: an Active Exploration of Mathematical Language

This text provides an introduction writing mathematical proofs. It emphasizes structure through logical forms, and introduces students to common proof techniques such as contradiction, contrapositive, and mathematical induction.

Prerequisites: Calculus I is helpful, but not fundamental.

Suggested course use: This material is appropriate for a standard one semester discrete math course for math and computer science students. It could also be used for a proof-writing bridge course.

## TBIL Activities for Understanding Linear Algebra

This is a supplement to David Austin's Understanding Linear Algebra. It provides versions of the text activities in a format to be used in a team-based inquiry learning classroom.

Suggested course use: This material is appropriate to uses as a supplement to Understanding Linear Algebra. It allows for classroom display of the activities in smaller segments in order to facilitate in class, team-based work on shorter problems. It includes some alternate forms for student responses, such as multiple choice.

These projects were developed thanks to the PreTeXt Project.
