Experience
I'm a passionate educator with over 11 years of experience in both primary and middle school classrooms. I’ve taught Math and served as a homeroom teacher, giving me a strong foundation in curriculum design and child-centered learning. My journey has now expanded into creating digital and printable resources that support parents, teachers, and young learners around the world.
Teaching style
My teaching approach is hands-on, engaging, and rooted in play-based learning. I believe children learn best when they’re having fun, so I create visually rich and interactive materials that spark curiosity and make complex concepts easier to understand—especially for young and ESL learners.
Awards & shining teacher moments
One of my proudest moments as a teacher was watching struggling students grow confident in math through interactive games and visuals I designed. While I haven’t received official awards, the smiles, progress, and feedback from my students and their parents have always been my greatest rewards.
My own education history
I hold a degree in Education and have completed various professional development courses focused on early childhood learning and differentiated instruction. My commitment to lifelong learning drives me to continually improve the resources I create.
Additional biographical information
As a mom and educator living abroad without local family support, I understand the value of time-saving, effective resources. That’s why I started Smartie Steps by Nardine S —to empower busy parents and teachers with tools that are easy to use and loved by children. Every product is made with care, combining my real-life classroom experience with a mother's heart.
