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.

Child using color-coded word cards to explore pronouns in a Montessori language activity.
March 9, 2026
When children begin working with pronouns in Montessori, they are not learning something entirely new. Instead, they are bringing to consciousness language they already use every day. Pronoun work builds slowly and intentionally. It is not about mastering grammar rules, but about understanding how language functions and how meaning is carried when words stand in for one another. Beginning With Experience, Not Explanation Montessori pronoun work begins with movement and spoken language, not written grammar. We start with little oral games to highlight how a pronoun functions, sometimes eliminating the pronoun (“Josie and John and Jack and Josiah are walking around the table.”) and other times emphasizing the pronoun (“They are walking around the table.”). The children love acting out the phrases, sometimes chanting, moving, watching one another, and laughing. Through these physical experiences, they begin to notice that we don’t always use names when we speak. Certain words take the place of a noun, and the meaning is still clear. At this stage, we don’t offer the term pronoun because we want children to simply experience its function. From Movement to Sentences Once children are ready for more structured language work, we introduce them to the Pronoun Grammar Box so they can build and rebuild sentences using color-coded cards for each part of speech. From one sentence to the next, only a few words change as nouns get replaced by pronouns. By comparing sentences, children discover that although the word changes, the sentence still makes sense. This comparison is essential. Rather than being told what a pronoun is, children see what it does. We then invite children to add grammar symbols to the sentence (noun, article, adjective, verb, preposition, adverb) until we finally draw attention to the remaining word: “This word is used in place of a noun.” Only then do we introduce the pronoun symbol: a purple isosceles triangle, the height of the noun symbol. Montessori Lore: The Pronoun’s Story There’s a beloved story about the pronoun symbol. Long ago, the pronoun was shorter and a different color. Wanting to be as important as the noun, it stretched itself taller and taller to reach the same height. As it stretched, its base became smaller and it turned purple from the effort of standing in the noun’s place. It’s a poetic reminder of what children discover through their work: a pronoun depends on the noun, borrowing its meaning while standing in for it. Why Pronouns Come Later Pronouns are more abstract than other parts of speech. To understand a pronoun, children must already have a strong, concrete understanding of the noun. For this reason, pronouns (along with interjections) are typically introduced later than other grammar symbols, often in the elementary years. Even then, one lesson is not enough. In Montessori, the real learning happens after the presentation, when we step back and children work independently with the material. The guide’s role is to show how to use the material, not to explain grammar in detail. Understanding emerges through repeated use. Deepening Understanding Through Play and Exploration As children grow more confident, the work expands to include: Transposition games, where pronouns are removed or replaced to explore how meaning changes. Command cards, which physically isolate pronouns through action. Personal pronoun charts, introducing first, second, and third person (singular and plural) through storytelling. The Verb Family, where children explore the close relationship between the verb, adverb, and pronoun. Children discover that pronouns often work closely with verbs, helping to carry action and meaning through a sentence. Subtleties Come Later At first, Montessori avoids getting caught in fine distinctions. Over time, children may explore nuances such as the difference between possessive pronouns (the book is mine) and possessive adjectives (my book). These discussions often happen later, sometimes with the support of grammar references, once children have a solid foundation. Language Revealed, Not Taught Through this carefully layered progression of movement, sentence work, symbols, and exploration, children develop a deep understanding of how words function differently in sentences. Montessori grammar invites children to discover how language works at their own pace through hands-on exploration. We don’t rush this process. So by the time children are ready to name the pronoun, it’s not a new idea. It’s something they already know. We invite you to visit our classrooms in Delran, New Jersey to see firsthand the children’s joy of learning!
