Brief Background:
Upon graduating from Florida State, Mr. Leljedal began his math teaching career at Tallahassee Community College and Franklin Academy. His passion for mathematics motivated him to pursue a Master’s degree while teaching in the Broward County Public School District. Before joining Oxbridge Academy in 2019, he taught at Oak Hall School and served as an adjunct professor at Santa Fe College, both in Gainesville, Florida.
Oxbridge Academy offers various math courses, all incorporating problem-solving and logic.
The Math Department believes that students must learn how to creatively solve problems and apply quantitative skills learned in class to real-world situations. We strive to help students apply and explain logical processes, find practical uses for those concepts in their daily lives, and seek to instill a growth mindset in our students that will help them embrace the challenges they face in mathematics and beyond.
We offer the traditional coursework of Pre-Algebra through Calculus, along with advanced courses like Multivariable Calculus and Differential Equations. Our unique electives, like AI/Math Modeling, Digital Logic, and Computer Science, apply math to concrete, real-world scenarios. Upon completing our curriculum, students can think deeply about problems and persevere to keep trying when their first answer is incorrect.
