At York Montessori School, we believe that STEM learning begins long before formal lessons in science or math. Montessori sensorial materials give children aged two to six the tools to explore, notice patterns, and approach challenges through concrete, engaging experiences. When children build the Pink Tower, arrange the Knobbed Cylinders, or investigate the Geometric Solids, they refine their senses while developing reasoning, spatial awareness, and logic. These skills form the foundation for science, technology, engineering, and mathematics. Sensorial experiences also allow children to experiment safely, test ideas, and gain confidence, fostering resilience and the courage to try new approaches, abilities that are critical both in STEM and in life.
Research supports this approach. Developmental psychologist Dr. Angeline Lillard, a leading expert on Montessori education, explains that Montessori environments naturally foster the cognitive abilities essential for later STEM success. Immersive learning with sensorial materials helps children notice details, make connections, and think critically as they explore and refine their ideas, while encouraging them to take measures, risks and learn from trial and error. These experiences strengthen persistence, flexibility, and self-assurance. In her video, Montessori: The Science – Part 1, Dr. Lillard introduces the science behind Montessori learning in a clear, accessible way for parents, highlighting how sensorial explorations guide children’s thinking from the earliest years. Longitudinal research also shows that children in Montessori programs develop stronger executive function and early math skills compared with peers in traditional preschools, providing a solid foundation for future STEM learning.
At YMS, we bring these principles to life in ways that ignite curiosity, exploration, and confidence. Our classrooms are designed so that children can engage with sensorial experiences at their own pace, encouraging independent thinking and the ability to approach challenges creatively. Educators observe and provide gentle guidance to help students notice patterns, explore solutions, and refine techniques. Whether children are manipulating the Constructive Triangles, organizing the Brown Stair, or exploring the shapes of the Geometric Cabinet, they are practicing the very skills that will serve them in future STEM learning while strengthening resilience and the courage to embrace new experiences. Through repeated engagement and self-discovery, our students deepen both their understanding of the physical world and the cognitive tools and confidence they will carry into all areas of learning.
