Including School Mathematics Teaching Applications in an Undergraduate Abstract Algebra Course

We describe the design and implementation of lessons in undergraduate abstract algebra that integrate applications to teaching high school mathematics. Each lesson consists a pre-activity, class activity, homework set, assessment questions detailed instructor notes. The included intend bridge advanced mathematics concepts secondary content for prospective teachers, as well provide instructors with useful resource. includes four guiding features: addressing meaningful content; making connections teaching; emphasizing active learning; providing comprehensive notes instructors. Interviews their students document how adapted classrooms influenced undergraduates' mathematical understanding.
