About the Course

Introduction to Logic and Proofs

Explore advanced mathematical concepts in fun and interesting ways and build a strong foundation for high school, computer science, and college-level logic coursework in this introductory logic class.

Through logic puzzles, adaptive world arguments, peer collaboration and feedback, you’ll strengthen your understanding of mathematics and sharpen your problem-solving skills as you delve into these key mathematical ideas.

This course is ideal for curious students who are eager to deepen their understanding of mathematics through games, world applications, and collaboration.

In addition to weekly virtual class meetings, students may schedule weekly one-on-one virtual meetings directly with the instructor to answer questions or concerns.

Meeting times
In this course, students are required to attend scheduled online meetings. These online meetings may be used to conduct class sessions, office hours, group work, or other instructional needs. Your instructor will communicate with you to schedule the first virtual class meeting and inform you of subsequent meeting days/times.

The class will meet 1 day each week, for 1 hour.

In the event you have a scheduling conflict, and cannot attend the synchronous meeting, contact your instructor prior to the meeting.

Time Commitment: 2-4 hours per week (1-hour of class time, 1-3 hours of independent work).
