Our Montessori Dictionary

Montessori School of Louisville • December 30, 2024

We recognize that Montessori education can have some lingo that might need a little explanation. So in this Montessori Dictionary post, we’re going to focus on a few terms (some familiar, some perhaps not so familiar) that apply to both the early childhood years and beyond. 


When possible, we’ve included some quotes from Dr. Maria Montessori and we encourage you to take a look at her work. Dr. Montessori was a woman well before her time and her books, such as From Childhood to Adolescence and To Educate the Human Potential, can be a source of insight and inspiration!


Grace and Courtesy


Grace and courtesy is an essential aspect of Montessori environments and supports children as they develop social relationships. Grace is how we move through the space around us, and courtesy is how we treat each other. 


In the Montessori early childhood classroom, grace and courtesy is considered one of the areas of practical life. For example, adults give lessons on how to interrupt, how to accept an offering, how to offer help, or how to introduce oneself. These lessons are offered in small groups and the technique used is role-playing. Little social scenarios are acted out and provide a model for behavior that is situational. Like all other learning activities, grace and courtesy lessons are practiced and repeated. They provide a respectful way of learning expectations and aiding social skills before they are needed.


Grace and courtesy is never offered as a form of punishment or correction. We make sure children don’t experience embarrassment by being corrected by adults on the spot, as this makes children feel disrespected and not safe. Dr. Montessori reminds us of this in The Secret of Childhood: “I have come to appreciate the fact that children have a deep sense of personal dignity. Adults, as a rule, have no concept of how easily they are wounded and oppressed.” In time, if we offer these grace and courtesy lessons, and give children a safe place to practice, children will eventually perform these skills independently. 


Human Tendencies


Human tendencies are unconscious, universal drives that support our adaptation to our particular time and place. All humans are born with innate needs and drives and are wired to adapt to their environment. The human tendencies – to orient, explore, order, abstract, imagine, calculate, work, be exact and repeat, perfect oneself, and communicate and associate with others – help aid this adaptation.  


Dr. Montessori alluded to human tendencies when she wrote about the inner drive she observed in children and how this drive helps individuals construct themselves to develop into maturity: “Their behavior led us to become aware of a fundamental truth, namely that the child works for his own inner development and not to reach an exterior aim and that when he has done this work he has not really developed a special ability but he has developed something in himself.” 


Prepared Environment


The Montessori environment is carefully prepared so that children can satisfy their human tendencies and thus develop to their fullest potential. The prepared environment takes into consideration what children need at their particular stage of growth, and as individuals on their own trajectory of development. The prepared environment consists of the physical and psychic aspects of the environment, of which the adult is a key part. 


Through interactions in a prepared environment, children can construct who they are as human beings. As they go through this process of self-construction in their environment, children learn, grow, adapt, and create. The prepared environment is part of the triad of the child, the environment, and the adult, all of which are interconnected components. 


Sensitive Periods/Sensitivities


Dr. Montessori was first and foremost a scientist and she was interested in what was happening prior to observable signs of human development. She was curious about what was going on in the mind before the skill manifested itself. For example, she wanted to know what was happening during the many months prior to children speaking their first word. 


Without the high-tech tools that neuropsychologists and psychologists now have to measure brain activity, Dr. Montessori had to rely upon observation. She watched children, took notes, and made charts about what they did. As a result, she discovered that a particular object or aspect of the environment would have an irresistible draw for children. This attraction would last for some time. Children would keep going back to the same activity or element of the environment and would be continually drawn to it. Then the day would come when it held no more interest and something new would be attractive. 


Dr. Montessori observed this phenomenon over and over again, which led her to believe that there must be something innate in children that was driving this interest. Building upon the work of biologists, Dr. Montessori adopted the term, sensitive period, to describe transitory periods of psychic development. Beyond the Montessori world, sensitive periods are now referred to as critical periods or windows of opportunity.

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!
