Upper School Math
More About Jeremy
Jeremy Smart is excited to be returning to the classroom after taking the past few years to be a stay-at-home parent. While he has been teaching primarily upper school math courses for the better part of the past 22 years, his initial training and teaching was with young children at Bing Nursery School, a play-based, child-centered school associated with Stanford University, where he did his undergraduate work. He graduated having earned a BAS degree with a double major in mathematics and developmental psychology. While at Bing, Jeremy worked on teaching teams in a 2-year-old class and a mixed-age 3- through 5-year-old class, and he still credits his experiences with young children as foundational to his educational approaches across all ages.
As an upper school math teacher, Jeremy has always tried to implement student-centered, problem-based curricula whenever possible, which he first discovered while teaching summers at Phillips Exeter Academy, a boarding school in Exeter, NH. Jeremy took these experiences with him while teaching a wide range of upper school math courses for 12 years at Sacred Heart Schools in Atherton, CA and 4 years at The Dwight School in New York, NY. He has taught courses at both remedial and advanced/AP levels as well as courses within the International Baccalaureate (IB) program at the Middle Years and Diploma Programme levels. Jeremy also developed a post-AP Calculus senior-level course for prospective mathematics majors, designed to introduce them to a wide range of topics that could reasonably be encountered at the university level. At various times throughout his teaching, he has served as an advisor for seniors completing their IB theses, a mentor to beginning teachers, a class advisor, and an assistant director for a senior retreat program.
While teaching in New York, Jeremy also earned his MA in mathematics education at Teachers College, Columbia University. He enjoyed his time in the program so much that he decided to continue taking courses until he practically exhausted the options available to him at the time before returning to California to teach once again, and remained in the classroom for 8 more years before deciding to take time off to stay home with his children.
Jeremy lives with his wife, Kellie, an elementary music teacher, his 8-year-old daughter, and 4-year-old son. He enjoys playing guitar, being in nature, cooking for his family, and reading well-thought-out children’s stories to his own kids.
