Our Montessori Dictionary
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 primary 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.

In Montessori education, we emphasize community, not just as an abstract concept, but as a lived daily experience. From the very beginning of life, we emphasize carefully prepared environments that foster a deep sense of belonging and connection. What Is Community? The word community comes from the Latin communis , meaning “common, public, general, or shared by all or many.” In addition to shared space, in Montessori, we also think about community as a shared sense of meaning, values, and connection. At its core, community begins with the most fundamental human group: the family. Families form children’s first social experience and the first place where values, culture, and expectations are passed down. This bond has helped humans survive and thrive throughout history. Partnering with Families In the Montessori approach, we honor and respect each family's unique values, striving to foster strong home-school relationships. Our partnership with families is a mutual journey—one in which the adult caregivers at school and home come together with a shared purpose: to nurture children’s natural growth. Building the Toddler Community We design our learning environments—both indoors and outdoors—to meet each child where they are, providing just the right level of challenge, comfort, and beauty. In creating community, we focus on essential, concrete elements like people, space, and materials, while also attending to intangible aspects that provide a profound sense of order. The People : The adults—both the lead guide and trained assistants—focus on personal and professional preparation. Their role is not to direct the child but to support their natural development with presence, purpose, and peacefulness. The Space : The physical environment must be appropriately sized, thoughtfully arranged, and aesthetically pleasing. If it’s too large, children can feel lost or overstimulated. If it’s too small, they may feel crowded and unsettled. We design every detail—from the furniture to the flow of the day—with intention. The Materials : Everything in the classroom is purposeful, developmentally appropriate, and in harmony with Montessori principles. We carefully select materials to support children’s movement, independence, concentration, and sense of order. Profound Order : A true Montessori community also relies on an invisible but essential structure: the order that underlies everything. Children have a fundamental need for order, especially during the first six years of life when they are in their sensitive period for order. External order—seen in routines, consistent expectations, and a well-organized space—helps children form inner order, which is the foundation of emotional regulation, concentration, and autonomy. If children do not experience order in their lives, they must expend energy trying to create it—energy that should instead be used for self-construction. That is why order must exist not just in the physical environment, but also in the adults’ behavior and in the flow of the day. A sense of control, predictability, and respect enables toddlers to flourish as they begin to form their personalities. The Role of the Prepared Adult As we create and cultivate our learning communities, we also recognize the significance of our role as adults in creating a community where toddlers feel safe, supported, and free to grow. While we play a critical role in creating and maintaining a beautiful environment, we also recognize that it belongs to the children for their growth and development. To ensure that we support this development, we strive to master the art of observation, which enables us to identify what children need to aid their growth. With a deep understanding of the purpose of every material in the classroom, we can then connect children to meaningful work through intentional and respectful presentations. We also practice humility, recognizing that children are often more in tune with their needs than we are. Our work with toddlers requires us to respect each child’s human potential, even when behavior is challenging, and to love unconditionally, accepting children for who they are, not who we want them to be. This practice means that we regularly reflect on our own work, always striving to improve so that we can better serve the children. A Living, Breathing Community Creating a Montessori community for toddlers is both an art and a science that requires intentional environments, well-prepared adults, and a deep respect for children’s developmental journey. At its heart, the Montessori Toddler Community is a shared space where children learn how to be in the world—together. It is here they first experience what it means to belong, to contribute, and to grow with others. Schedule a visit to see what an intentionally designed community looks like in action!
