The Capstone Years
Didem Bugay • February 5, 2024

There are key times in children’s lives when they can consolidate emerging parts of themselves before moving into a new area of growth and change. Three significant times of change for young people are around age six, around age twelve, and around age fifteen, the Kindergarten, 6th-grade, and high school freshman years. Both biology and Montessori theory offer insight into why these are significant times in children’s lives.  


Montessori’s Planes of Development


Dr. Maria Montessori believed that children’s work is to construct the adults they will become. This is really important work! Adults can support children’s self-construction, but not do it for them. Children can accomplish self-construction through their activities and interactions with the environment. 


Dr. Montessori’s observations of this self-construction led her to develop a theory of four planes of development. When looking at children’s development from a scientist’s point of view, Dr. Montessori found that development did not occur steadily but rather occurred in phases or planes. Dr. Montessori considered that the change in children, as they moved from one plane to another, was so profound that it resembled a rebirth.


Each plane or phase of development lasts for approximately six years: infancy (0 to 6), childhood (6 to 12), adolescence (12 to 18), and adulthood (18 to 24). The turning point around age six is when children move from infancy into childhood, around age twelve they move from childhood into adolescence, and around fifteen young adults feel more settled, stable, and confident in themselves.


Biological Changes


Biologically, considerable hormonal changes are happening during these two transition times in children’s lives. While our society generally recognizes the biological shifts as young people move into adolescence, we are less well-versed about what happens in our six-year-olds. 


It doesn’t take much, though, to realize change is afoot! Think about what we see in terms of dramatic physical changes around age six: their teeth start to fall out, their hair gets coarser, they lose that baby-soft skin, and they become leaner and lanky. Similarly, our twelve-year-olds are on the brink of adolescence, another period of dramatic physical growth and change. Our fifteen-year-olds are learning who they are as individuals and crave social independence.  


However, there can be a gap between these physical signs of maturity and the cognitive and emotional development happening for our six-year-olds and twelve-year-olds. Often children at these ages are moved too quickly into an environment that doesn’t meet their needs and doesn’t honor the internal growth that still needs to occur. When this happens, they lose the environmental stability that allows them to develop a deeper sense of self-confidence and to truly consolidate the intellectual and emotional skills they have been developing over the previous years.


Capstone Years at Wheaton Montessori School


We recognize the importance of these transitional years and intentionally design our classrooms to support our students during this time. The six-year-olds and twelve-year-olds are the oldest in our Primary (Preschool and Kindergarten) classroom and Upper Elementary classroom respectively and fifteen-year-old freshmen are the oldest, by design, in our Adolescent Community. They know the routines and expectations, they have secure relationships, and they get to help others who are newer to the classroom communities. 


Because they aren’t trying to assimilate into a new environment, our six-, twelve-, and fifteen-year-olds can serve as leaders for their mixed-age classrooms. They can focus on challenging work and big personal achievements. By being with their younger classmates, they can see where they have grown up and how they got to where they are now. 


These are the capstone years, the final piece to complete the critical building-up that has been happening during the previous formative years. The level of mastery allows our six-year-old, twelve-year-old, and fifteen-year-old leaders to integrate their social, emotional, and intellectual selves. 


During these capstone years, children gain a sense of self-confidence and self-satisfaction from successfully navigating the bigger projects and bigger conversations. The younger learners in the classroom communities are working toward these capstone capabilities and admire the oldests’ social, emotional, and academic strengths. All of these realizations are within a community of adults and peers who have shared their learning experiences over several years.


By having the opportunity to integrate their learning in a safe, stable, and secure environment, our young learners can do their important work of self-construction. 


Wheaton Montessori School’s carefully designed programs meet each child’s age-specific needs and follow the stages of development identified by Dr. Maria Montessori which research keeps confirming. Completing each program’s cycle is ideal for the development of the person.

Montessori Mayhem? Pint-Sized Pandemonium? When I give tours of the Elementary classrooms or welcome new parents to the Elementary program at Wheaton Montessori School, some parents believe that students are allowed complete freedom, as if the classrooms are a beautiful den of chaos and anarchy. Indeed, this is one of the biggest misconceptions about Montessori education. (The biggest misconception being, in my experience, that Montessori isn’t “real world” education. But as we say in our lessons, “That’s a story for another day.”) While Montessori classrooms DO give children the freedoms they require and deserve, it’s not an unlimited free-for-all with an adult watching from an observation chair! Freedom is always balanced with responsibility, to oneself and to the community. These values, freedom and responsibility, are essential for creating a happy, busy, humming classroom where children thrive. What Does Freedom Mean in Our Classroom? “Freedom” in the classroom means that students are encouraged to make choices about their learning. Just as in our Primary classrooms at Wheaton Montessori School, students are free to choose their work, their seat, and their work partners. They are free to move about the classroom and do not need to raise their hands to visit the restroom, get a drink of water, or ask a question. Let’s look at a few of these freedoms more closely. Students are Free to Choose Their Work. For example, they may choose which book to read, choose a work partner to research a chosen topic, or practice a tricky bit of a lesson over and over. They are also able to choose how they will show their understanding. They might present their understanding through a poster, a diorama, a model, a handmade book, or an enormous amount of cardboard and hot glue. These choices empower students to take charge of their education and express themselves in ways that suit their interests and strengths, something a standardized test or a worksheet can never do. However, freedom in the classroom ALWAYS has limits. For example, students are free to choose their work, but choosing NOT to work is not an option. They are free to choose their work from the lessons that have been presented to them. While students may choose their reading material, it must be appropriate for their reading level and classroom guidelines. When students select a partner, they must do so respectfully and inclusively. When students create projects and work output, they must do so with care, make proper use of materials, and in a way that shows what they understand about their topic. Additionally, these choices should never disrupt their own learning and construction, or that of their peers. The Role of Responsibility In a true Montessori classroom, freedom comes with responsibility. And that responsibility can sometimes be uncomfortable at first. Students are expected to care for classroom materials, such as returning books and lesson materials to the shelf, taking part in classroom jobs, keeping a record of their work in their work journals, and handling art supplies properly. They are responsible for practicing their lessons and completing chosen follow-up work, listening attentively during lessons or when a classmate is sharing a presentation or thought, and helping classmates when needed and available. A student is not free to use materials in a way that damages or wastes the classroom supplies or puts anyone in harm’s way. Freedom within our classroom never allows for harming oneself, others, or the classroom materials. Healthy boundaries, limits, and structures are consistently communicated in advance with clarity and respect, ensuring practicality and alignment within the community. Classroom expectations and rules are collaboratively developed and agreed upon by the community. In order to foster a positive learning environment, both students and teachers are expected to adhere to the shared expectations and responsibilities. When necessary, the classroom adult will address students and reiterate expectations and boundaries in a firm yet considerate manner. This balanced approach is effective only when maintained consistently throughout each day. What Might it Look Like When the Balance Needs to Shift? The adults in the classroom are constantly observing the children to be sure that each child has as much freedom as they are ready for, providing them space, room, and opportunities to show their strengths, and make their own choices throughout the day. When that freedom is too much, a teacher might need to provide more lessons in how to use materials that have been damaged or used improperly, limit work partner choices, or have a student sit with the teacher while they practice lessons or work with precious art materials. The adults will be watching for the perfect moment to allow the child increased freedom within the classroom, and within the limits of the understood responsibilities. How Freedom and Responsibility Work Together Finding the right mix of freedom and responsibility is something we work on together every day in our classroom. Montessori teachers are specially trained to guide this balance, helping students practice important skills like making good choices, solving problems, and learning self-control. When children are trusted to make decisions, they also learn to take responsibility for those choices. Experiencing the natural consequences of their actions helps them become kind, thoughtful, and capable members of their community who understand how their choices affect others. What Does This Have to Do with Parents? Your support at home makes a big difference. By working together, we can help your child thrive both at school and at home. Encouraging your child to take responsibility for their actions and decisions reinforces what they learn in class. Yes, it can be uncomfortable, but it is necessary. It also becomes easier, more comfortable, and needs to be practiced less often when practiced consistently (like most things!). This supportive consistency across settings, at home and at school, helps children feel confident, cared for, and increasingly independent.
