Our Team

[Sarah] + Schaefer

Principal, Mathodology, Atlantic Beach, FL


Sarah Schaefer, M.Ed., is the founder of Mathodology, contributing author of think!Mathematics, and lead author of Developing Roots (Kindergarten).  She has been teaching K-12 Mathematics in public and private schools since 1995. She understands your challenges when it comes to teaching and learning mathematics as she has lived the process. 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 implementing the Singapore curriculum, both nationally and internationally, 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 understand mathematics, resulting in a more valuable and meaningful learning environment.

[Fran] + Julien

Learning Services Administrator

Fran began her teaching career in 2014 after graduating from the University of South Florida, earning a Bachelor of Science in Elementary Education from the nationally recognized Urban Residency Teacher Partnership Program. She began her work in public schools in Tampa, Florida, teaching mainly Math and Science in grades 3 – 5. As her personal philosophy of teaching began to evolve, she decided to accept a teaching position at a private school in Knoxville, Tennessee in 2018. There, Fran had the autonomy to develop curriculum and authentic educational experiences for her students. She has worked to empower students to understand themselves as learners. Upon returning to her hometown this year, she is transitioning from her career as a classroom teacher to live out a developing passion of hers: building teacher efficacy and strengthening pedagogical approaches in fellow educators. 

Fran brings the perspective of an educator who has had the opportunity to implement practices of the Singapore methodology through Mathodology and think! Mathematics in her own classroom of fourth and fifth graders. As a result, she was able to witness monumental improvements in her students’ confidence and abilities as mathematicians. This further ignited her need to empower more educators to make small, but impactful changes in their classrooms and teaching practices in order to maximize student development. 

Fran was born and raised in Land O’ Lakes, Florida. She likes to travel, loves coffee, and stays strongly connected to her local community. Aside from teaching, Fran’s heart is dedicated to volunteering and working alongside organizations that serve communities in Haiti. When she’s not working, you can find Fran enjoying local coffee shops, working out, planning her next waterfall hike, or spending time with friends and family.

She has taught in both the private and public sector including second grade and fifth grade at The Bolles School in Jacksonville, FL and currently teaches pre-first at the Westminster School in Atlanta.  Melissa believes students need to be given the opportunity to experience math by exploring, playing, questioning, and discovering. She feels it is important for the teacher to create an environment that fosters these characteristics so students become engaged and ultimately enjoy mathematics. In her classroom, students are often seen playing math games and having hands-on experiences that enrich their understanding and love for math.  Her journey with the Singapore approach began when she taught second grade at The Bolles School. They used Math in Focus as their text and Sarah Schaefer helped them create anchor tasks to include all students and to enrich their math curriculum. Melissa later moved to Atlanta and became a Pre-First teacher. Last year she was given the opportunity to pilot Developing Roots and then adopted the program the next year.  Melissa believes in her community and participates in the Beach Clean-Up Crew of St. Augustine. She is the Teacher of the Year recipient for 2002 and 2003 and an Ottenstroer Grant recipient.  Melissa’s husband is a retired Naval pilot.

“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!”
