Experience
"My journey in mathematics education began in 2009. Currently, I serve as university faculty, where my primary role is mentoring future mathematics teachers.
With a background that includes teaching Instructional Design and mathematics pedagogy at the university level, I approach resource creation through a lens of rigorous academic standards and practical application.
My unique perspective comes from years of supervising student teachers in primary and secondary classrooms. Observing recurring foundational gaps in older students has driven my passion to create specialized K-1 resources. I utilize my expertise to design tools based on the Science of Math, ensuring that young learners build the deep, conceptual understanding necessary to prevent future struggles."
Teaching style
"My approach to mathematics education is deeply rooted in evidence-based practices and the principles of the Science of Math. As a university professor training future educators, I don't just teach mathematical concepts; I teach the pedagogy of how students truly learn them.
I believe that early mathematics must move beyond rote memorization. My resources are engineered to build profound conceptual understanding first. I emphasize structured scaffolding—often utilizing the Concrete-Representational-Abstract (CRA) sequence—to ensure young learners develop a solid, unshakable foundation before moving to procedural fluency. Every resource I create is designed to bridge the gap between academic research and practical, effective classroom application."
Awards & shining teacher moments
"While I value professional recognitions, my true 'shining moments' aren't medallions or certificates; they are the success stories of the future teachers I have mentored.
The greatest reward in my career is witnessing my university students blossom into capable, passionate mathematics educators. Seeing them enter classrooms equipped with the right pedagogical tools—specifically the ability to build strong conceptual foundations in young learners—is incredibly fulfilling. Knowing that the principles of effective math instruction I've instilled in them will create a positive 'ripple effect,' impacting thousands of students throughout their careers, is the highest honor I could achieve."
My own education history
"My educational background forms the bedrock of my expertise in creating high-quality math resources. I hold a Master of Science in Mathematics (M.Sc.), which gives me a deep and structured understanding of the mathematical progressions students will face throughout their academic journey.
Currently serving as university faculty, my academic focus lies in Mathematics Pedagogy and Instructional Design. This unique combination—possessing advanced content knowledge and expertise in how to design effective learning experiences—directly informs every product in my store. Furthermore, I am deeply committed to continuous professional development, regularly participating in teacher training and educational research to ensure my methods remain current and evidence-based."
Additional biographical information
"It might seem unusual, but my primary hobby is exactly what you see in this store. When I am not lecturing at the university or supervising student teachers, I can most often be found sitting quietly, designing new no-prep resources.
For me, the challenge of translating complex mathematical theory into simple, engaging, and practical worksheets for young learners is not just 'work'—it is my creative outlet and passion. I genuinely love the intricate process of crafting tools that will eventually make life easier for busy teachers and light up a child’s understanding of mathematics."
