In the Fall 2021 semester, I was a Tomlinson Engagement Awardee for Mentoring (TEAM Mentor or TEAMster) in the course MATH 133 Linear Algebra and Geometry at McGill University. I authored the following write-ups about interesting applications and connections of linear algebra to other areas of mathematics, computer science, etc., corresponding to the progress of the course. Feel free to have a look if you are interested!
