Our Team

[Sarah] + Schaefer

Principal, Mathodology, Atlantic Beach, FL

Sarah Schaefer, M.Ed., has been teaching K-12 Mathematics in public and private school settings since 1995. She understands your challenges when it comes to teaching and learning mathematics because she’s lived through her own. Schedules are limited. Classes are short. Change is constant. Teachers are being pulled in many directions while looking for ways to connect with students to enhance their understanding of mathematical content. As an early adopter of the Singapore methodology, Sarah’s iterative approach optimizes performance and maximizes knowledge retention. Sarah is passionate about mathematics, teaching, and creating relationships that result in deeper content knowledge. Her extensive experience in implementing the Singapore curriculum has involved not only students and teachers, but leading institutes which have adopted her collaborative process.  While teaching at the prestigious Bolles School, Sarah created the curriculum from the ground up by simplifying and focusing on delivery and developing content knowledge. She empowers teachers, students, and parents to be creative in how they think about and understanding mathematics, which results in a more valuable and meaningful learning environment.

“Sarah Schaefer's work has been transformational for our Lower School at Lovett. She is an educator of rare form, who demonstrated such depth of mathematical knowledge and understanding as well as children and adults as learners. Our entire community - of administrators, teachers, and parents - have been in awe of her intelligence, critical thinking, humility, and humor. At ease with every age of child and every type of learner, our teachers were eager to learn from and with Sarah. They continuously clamored for more time with her and named their professional development with Sarah as the most powerful of the year. No other consultant, workshop, or conference has had such a profound effect on how we teach math. Sarah's work and presence have truly been invaluable!”
