The Planes of Development
October 4, 2021

Maria Montessori based her entire educational philosophy on the idea that children developed through a series of four planes. Each of these planes is easy to recognize and has clear, defining characteristics. If we study and understand these stages, we can approach our interactions with children with a new perspective. 

The Four Planes of Development

Learning about the planes of development isn’t just for Montessori educators. Understanding your child’s development can help at home, too. 


The First Plane: birth-6 years


During this stage children absorb everything like sponges. They are, indeed, excellent examples if what Montessori called ‘The Absorbent Mind.’ This is a time in which we are able to utilize what Montessori called sensitive periods of learning. While each child is different, there are typical patterns that emerge in regards to brain development and general readiness to learn particular skills.


During the first three years of this plane, all learning is done outside of the child’s conscious mind. They learn by exploring their senses and interacting with their environment. During the second half of the plane, from about 3-6 years, children enter the conscious stage of learning. They learn by using their hands, and specialized materials in the Montessori classroom were developed with this consideration.


During this time, children have a wonderful sense of order. They are methodical and can appreciate the many steps involved in practical life lessons in their classrooms. The organization of the works on their classroom shelves is intentional, which appeals again to this sense of order.


The first plane is a time in which children proclaim, “I can do it myself”; it is a time of physical independence.


The Second Plane: 6-12 years


During the elementary years children begin to look outside themselves. They suddenly develop a strong desire to form peer groups. Previously, during the first plane, a child would be content to focus on their own work while sitting near others. In the second plane, a child is compelled to actually work with their friends. It is during this time that children are ready to learn about collaboration.


During the second plane there is a sudden and marked period of physical growth. This may be a contributing factor to the observation that many children of this age seem to lack an awareness of their body, often bumping into things and knocking things over. Children begin to lose their teeth around this time as well. Their sense of order and neatness tend to fade a bit during this plane.


Throughout the second plane, children’s imaginations are ignited. Since Montessori education is based in reality, we find ways to deliver real information to children through storytelling and other similar methods. For example, when teaching children about the beginnings of our universe, Montessori schools use what is called a Great Lesson. The first Great Lesson is a dramatic story, told to children with the use of props, experiments, and dramatics (think: a black balloon filled with glitter is popped to illustrate the Big Bang, with bits of paper in a dish of water used while talking about particles gathering together). This lesson is fascinating for children in the way it is presented, but gives them basic information about the solar system, states of matter, and other important concepts.


Children in the second plane have a voracious appetite for information, and are often drawn strongly to what we in Montessori call the cultural subjects: science, history, and geography. While we support their rapid language and mathematical growth during this time, we are also responsible for providing them with a variety of rich cultural lessons and experiences.


It is important to note that children develop a sense of moral justice at this time. They are very concerned with what is fair, and creating the rules to a new game is often as important (if not more so) than playing the actual game itself.


This is the period of time in which children are striving for intellectual independence.


The Third Plane: 12-18


The third plane of development encompasses the adolescent years. During the second plane, children become aware of social connections, but in the third plane they are critical. During this time children rely heavily on their relationships with their peers. They feel a strong desire to remain independent from adults, although they are not quite ready to do this entirely. It is our job to find ways that allow them to experiment with independence while also providing a safe structure in which they may do so.


Children in the third plane tend to require more sleep, and they sleep later than when they were younger. They long for authentic learning experiences, and Dr. Montessori imagined just that. Her ideas of Erdkinder (children of the earth) led her to contemplate a school setting that would support children’s development during this time. She imagined a farm school, in which children would work to keep the farm operational, but also contribute to planning and decision making while doing so. 


During the third plane children are refining their moral compass while developing a stronger sense of responsibility.


The Fourth Plane: 18-24



The final plane is a time in which young adults are striving for financial independence. They are often living away from home for the first time, and use this time to figure out where they fit into their society. Many make choices to further their education and/or explore career paths.


It is during the fourth plane that people begin to develop a truer sense of who they are as individuals.


Each plane of development should be mindfully nurtured. If a child is able to experience one developmental phase in a rich and carefully prepared environment, they are ready to fully take on the next phase when it is time.

Our school community was thrilled to experience the "Silent Journey," a unique and insightful event showcasing the TRIS Montessori curriculum. This school year, the Silent Journey focused on the Trilingual Immersion Program we offer at The Renaissance International School. The Preschool/Kindergarten Programs offer Spanish or French and English immersion, and the Elementary Program offers Spanish, French, and English immersion with native-speaking Montessori guides. Why the Silent Journey? The Silent Journey isn't just a walkthrough; it's a carefully curated experience for parents that maps out a Montessori curriculum for children aged two to twelve and explains the Montessori philosophy and methodology behind the careful, child-centric, developmentally appropriate, and systematic approach to learning. The Silent Journey Experience - The Big Picture To The Nitty Gritty! The Silent Journey offered an opportunity to: Strengthen the school-home partnership: A better understanding of the curriculum and specific methodologies used in the classroom supports a child's learning journey and strengthens the essential partnership between home and school. Experiencing the Learning Continuum: Parents walked through our classrooms, observing the sequential progression of our language curriculum from Toddlers (ages 2-3) to Elementary (ages 6-12). This presentation allowed them to see the holistic development of language skills across all levels and how language studies intertwine with all subject areas in the Montessori classroom. Exploring Our Trilingual Immersion: Our program is built on the science of reading, emphasizing phonics and phonemic awareness. Parents could see how we cultivate these skills in our youngest learners. They also witnessed our unique approach to phonemic awareness, grammar, and parsing across English, French, and Spanish. Witness the Montessori Method in Action: Parents observed how Montessori materials and principles work together in learning. They discovered the thoughtfulness and intentionality behind the Montessori Method. This included the vast array of materials for all language study components such as phonology, syntax, semantics, etc., how Montessori guides give lessons to introduce, reinforce, and retain concepts, and the design of materials and how they foster independence, promote self-directed learning, and nurture a love of exploration. They saw materials and methodologies that empowered their children to learn and practice concepts independently and at their own pace, becoming active drivers of their learning. From Observer to Participant - Stepping into a Montessori Student's World : After their silent observation, parents received lessons from our Montessori guides and enjoyed the hands-on experience of being a Montessori student. Understanding the Form and Function of Montessori Materials: Parents better understood the Montessori Language materials and how they enable a deep conceptual understanding of study areas. Overall, the Silent Journey experience was a great success and helped parents gain a deeper appreciation and understanding of the Montessori Method, with many parents remarking, " I wish I had learned the Montessori way!

Reading is often described as a gateway to new worlds, a bridge to understanding, and a sanctuary for the mind. Its benefits are myriad and go far beyond simple entertainment. Books provide a unique escape from reality. One can spend an entire afternoon climbing the Citadel with Rudi Matt , traveling through space and time with Meg Murray , or befriending a gorilla named Ivan . Books also have the ability to help develop empathy. By stepping into the shoes of diverse characters, readers can experience situations and perspectives that differ from their own. They can experience the ups and downs of moving from a Japanese community in Iowa to the deep south of Georgia , learn how it feels to have a stutter , or see what it is like to adopt an orphaned gosling . Reading also provides us with a way to gain more information about history, science, or really any human knowledge. Through reading, we can learn about World War II , extraordinary women who have contributed to society, and so much more. It is all the more concerning that recently a series of articles have come out discussing the concern among university professors about the decline of reading levels among their students. Professors across the board are finding that their students are unable to engage in the type of literature or academic reading that was once expected, even ten years ago. These articles point to social media usage, shortened attention spans, and high schools that do not ask their students to read entire books, as some of the reasons for the changes that are being seen. It is clearly a complex topic, and it is unlikely that there is one factor that is to blame, however, the topic has made me reflect on the importance of cultivating a reading culture and habit from a young age. Being an avid reader has long-term benefits. It is one of the avenues that allows humans to be life-long learners. Building the skills to concentrate, focus, and understand different types of books is critical to being able to access information in the world. We want our students to have the skills and knowledge to seek out information based on their interests and to always be curious about the world around them. In the long-term, reading also helps keep the brain engaged and active. As people age it helps stave off cognitive decline. Having built that strong foundation It is not just the act of reading which is important however, but what children are reading that is of equal importance. Choosing high quality books and content, however, is not always easy. What to look for when choosing books for your children Finding the right book for your child, at any reading level, can be a challenge. This is particularly true if they are resistant to reading independently (once they have reached a certain fluency level). There can be a temptation to therefore allow them to read any children’s literature out there - in fact, this is often recommended by librarians and other educators. We at TRIS, however, feel that there are some important factors that one must consider when choosing what literature to expose your child to. Here are some factors that we think are important as you choose books for your child: Values and Messaging One of the most important aspects of choosing literature for children is identifying what values and messaging are found in books. Think about what values and behaviors you would like to see your child embrace. If kindness and respect are important to you, be sure to find books in which respect and kindness are highlighted - not the opposite. Many children’s books depict “humorous” scenarios in which children are mean to each other, put each other down, or make jokes at the expense of others. While this may seem harmless, these messages impact your child and very often one will start to see a change in your child’s behavior. Language and Vocabulary It is important to trust that your child is able to understand and comprehend sophisticated language and vocabulary. Exposing them to sophisticated language from a young age is important. Believe that your children are capable of understanding challenging books. Read aloud with them frequently so that you can introduce them to words that on their own, they may not yet be able to understand. Style/Genre Children learn an immense amount from the books they read. Time and time again we see that strong writers are often avid readers. They are able to pick up style, tone and nuances of language when they read a variety of books. This is why it is so important that children are exposed to a wide variety of genres. It is important that they learn how to read more formal writing, as well as enjoy more informal writing. Being exposed to a large variety of genres opens the doors to their learning and adds to their arsenal of knowledge that they can then access later in life. Grammar There has been a rise in books geared toward early to mid readers in which the grammar is incorrect. Every time a child reads a book, they are building their knowledge about language. If they are being exposed to incorrect grammar, that is what they will learn and it will show up in their writing. Choose books that follow correct grammar and models desired writing. There are many other factors that may come into play when choosing a book for your child (this is whether they are reading it themselves or whether you are reading it with them) but the four criteria above are a good place to start. https://slate.com/human-interest/2024/02/literacy-crisis-reading-comprehension-college.html https://www.teenvogue.com/story/college-students-not-reading https://www.theatlantic.com/magazine/archive/2024/11/the-elite-college-students-who-cant-read-books/679945/ Renée Hites Head of School The Renaissance International School
