Montessori’s Five Great Lessons

Each year, Lower Elementary teachers share with their students Montessori’s story of the universe, the Five Great Lessons . The Five Great Lessons are the backbone of what Montessori called “Cosmic Education”; they form an overarching framework to which all the lessons of the classroom may be tied. Over the course of the school year, teachers bring these stories to life, stirring the imagination of students with an array of pictures, charts, science experiments, sound effects, lights – and sometimes even a fog machine!

Montessori viewed Cosmic Education to be at the heart of the correct education of children ages six through eleven. The child of six, educated in the Montessori method, enters the second plane of development with a controlled hand, a sense of order, the ability to work independently, and a wide foundation of factual knowledge. While she continues to learn by manipulating materials, she is increasingly able to think abstractly. More and more, she wants to understand relationships – the “why” behind facts and events. Montessori offered Cosmic Education as a means to satisfy the child’s mental hunger at this age, to organize and relate her factual knowledge, and also to ponder and discover her own place as a force in the cosmic plan. In Montessori’s words, “…let us give [the child] a vision of the whole universe…an imposing reality, and an answer to all questions…for all things are part of the universe, and are connected with each other to form one unity.”

What is the benefit of beginning with the big picture, of sharing the concept of the universe with the child of only six years of age? The vastness of the universe arouses the child’s interest and curiosity, inspiring admiration and wonder. It deepens the child’s understanding by providing a framework by which he organizes his knowledge, while sowing seeds for more in-depth pursuit of his own interests. Through cosmic education, the child’s “intelligence becomes whole…because of the vision of the whole which has been presented to him” (Montessori). Montessori believed that the “goal of good teaching is to enthuse [the child] to his inmost core”. The enormity of the story of the Cosmos inflames the child’s imagination and inspires him throughout his life to dig deeper into areas of study which are most meaningful to him.

The journey of the Five Great Lessons begins with the Coming of the Universe. This lesson is the most dramatic, as it explores scientific, cultural and religious explanations of how the universe and our planet Earth came to be. Over the course of the elementary years, this lesson launches the study of astronomy, meteorology, chemistry, physics, geology and geography.

The Second Great Lesson, The Coming of Life, describes the appearance of living organisms on Earth, beginning with single-celled plants and animals and ending with the appearance of humans. Through hands-on work with the Timeline of Life, students gain an overall impression of the great diversity of the microorganisms, plants and animals that have appeared at specific times to inhabit the Earth. The Second Great Lesson opens the doors to the study of plant and animal classification, habitats, anatomy, fossils, and life forms through different eras, as well as periods of extinction.

The final section of the Timeline of Life introduces the Third Great Lesson, The Coming of Humans. At this point, students are introduced to the Timeline of Humans and begin to examine from prehistoric through modern times, how humans have lived, met their fundamental needs, interacted with the natural world and each other, and thus shaped the course of history.

The Fourth Great Lesson, the Story of Writing , focuses man’s history on the development of a capability that is uniquely human – the capacity for written language! Students study different systems of writing that have evolved over the centuries and consider perhaps for the first time the impact of the recorded word on the advancement of civilizations and the body of knowledge that exists today.

The fifth and final Great Lesson is the Story of Numbers . This narrative begins with the simplest counting systems of early civilizations and explores how different number systems developed throughout history in different parts of the world. With this lesson as an introduction, students eventually study the many branches of mathematics and their applications, including numeration, basic operations, fractions, decimals, algebra, geometry, measurement, estimation, and money concepts.

Montessori’s Five Great Lessons serve both as a springboard into future studies and as a unifying point of reference for the child’s knowledge and all the lessons of the classroom. By raising consciousness of the interrelatedness of all that exists and each individual’s ability to impact the Cosmos, Montessori hoped to give to children a pathway to better understanding and a more unified, peaceful world.

More Than a Method: Honoring the Legacy of Dr. Maria Montessori
September 1, 2025
August 31 marked the birthday of Dr. Maria Montessori. Thus, we want to take time to honor the roots of this movement, the visionary contributions of Dr. Montessori herself, and our shared responsibility to carry her legacy forward. At the heart of Montessori education is a deep respect for human potential. Unlike traditional models that begin with the adult's idea of what a child should learn, the Montessori approach emerged from deep observation and genuine curiosity. Dr. Montessori did not set out to create a new educational system. Rather, she observed children with scientific curiosity and developed an approach in response to their needs. It’s important to remember that Dr. Montessori was first and foremost a scientist. She was one of the first female physicians in Italy, graduating in 1896 with a specialization in pediatrics and psychiatry. In her medical practice, she encountered children who were often seen as uneducable. However, rather than accept this assumption, Dr. Montessori looked closer. A Discovery That Changed Everything In 1900, Dr. Montessori was appointed director of a university program for children with developmental delays. Observing their sensory-seeking behaviors in bleak institutional settings, she began studying how sensory experiences affect cognitive development. She designed hands-on materials and engaged the children in purposeful activity. The results were stunning: children who had been dismissed by society not only improved, but some went on to pass the same standardized exams given to their peers in traditional schools. Dr. Montessori’s response was not one of self-congratulation. Instead, she challenged the broader education system, asking: If children with significant delays could thrive when given the right environment and tools, why weren’t typically developing children doing better in school? This question launched a lifetime of work dedicated to understanding and supporting the natural development of all children. The Birth of the Montessori Method In 1907, Dr. Montessori opened her first classroom, the Casa dei Bambini, in the working-class neighborhood of San Lorenzo in Rome. Tasked with overseeing daycare for children too young for public school, she began by introducing simple, practical activities, starting with self-care and environmental care. She also provided an array of materials designed to engage children’s hands and minds. The transformation was extraordinary. Children who had previously been described as wild and unruly became calm, focused, and joyful. They took pride in their appearance and their surroundings. They concentrated for long stretches of time, developed social awareness, and, unprompted, began asking to learn how to read and write. Dr. Montessori was fascinated by what she called “spontaneous discipline” and the deep love of work she observed in the children. Through observation and experimentation, she continued to refine the materials, the environment, and the adult's role. Education Rooted in Development What emerged was a revolutionary approach: an educational philosophy based on the science of human development. Rather than seeing the adult as the source of knowledge and the child as an empty vessel, Dr. Montessori recognized that children come into the world with innate potential and a deep drive to learn. Montessori education supports this natural unfolding by honoring what Dr. Montessori called human tendencies, such as exploration, orientation, order, communication, work, and repetition, through carefully prepared environments that meet the specific needs of each developmental stage. The adult's role is not to instruct, but to guide, observe, prepare, and support. This vision of human development extends beyond the individual to a larger understanding of humans as part of a cosmic web of interrelationships. In this interconnected world, every part plays a role in maintaining balance and harmony. Humans have a unique place in this system, and our role requires conscious awareness, humility, and stewardship. In addition to fostering rich academic growth, Montessori education cultivates mature, adaptive, and compassionate individuals who are capable of making meaningful contributions to our interconnected world. The Enduring Impact of Montessori’s Vision Dr. Montessori eventually left her medical practice and professorship to fully devote her life to this work. She lectured around the world, trained teachers, wrote extensively, and advocated for children’s rights. She also always insisted that the focus remain on the children, not on her. Through decades of scientific observation, experimentation, and cross-cultural study, Dr. Montessori discovered that children, when provided with the right conditions at the right time, flourish. Her insights have stood the test of time. Today, there are approximately 15,000 Montessori schools worldwide, with over 3,000 located in the United States alone. For over a century, Montessori education has empowered children to reach their full potential—academically, socially, and emotionally. Yet Montessori is not just about individual success. It’s about building a better society. We know that children are not just preparing for the future. They are the future. By focusing on children’s holistic development, we are supporting a generation of individuals who are more connected to themselves, to one another, and to the planet. Carrying the Legacy Forward Dr. Montessori’s vision asks us to do more than remember her birthday. We need to believe in children, observe them closely, and prepare environments that honor their needs. This also means that we, as adults, approach our role with humility and a sense of curiosity. Our job is to accompany children as they create the future. In this way, Montessori education becomes not just a method, but a movement, one rooted in peace, interdependence, and the full development of the human being. Thank you for being part of this vision. Together, here in Louisville, Kentucky, we are carrying the Montessori legacy forward, not only by what we teach, but by how we believe in the children before us. Come visit to learn more!
