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.

Without fail, most of my Parent-Teacher Conferences end with a parent asking, “What can we be doing at home?” And without fail, I respond, “Read. Read with them, to them, next to them, near them. Even if they read themselves. Keep them reading.” Reading is a skill that must be practiced, over and over again. Enjoying a book is not a skill that we’re born with in Kingdom Animalia. It’s a skill we learn by watching those around us, modeling reading as young children, trying over and over to find the book that hooks us for life. But what if your child doesn’t love reading? What if it’s a battle at home? Here are a few tips that I’ve learned from my fellow teachers, from my time as a parent, and from observing students in the classroom. Start early! Read to them as soon as you get them home for the first time! Not only does reading at a very early age have language comprehension, memory, and narrative skills implications for later in life, it also helps create a bond and habit early on. Feeling late to the party? Start now! Let them pick books they like. Are they choosing the same book again and again? Great! They’re reading! Are they reading the 8453rd installment of Rainbow Magic Fairies? Good! They’re reading! Diary of a Wimpy Kid? Great! The graphic novel of the comic based on the novel they already read? GREAT! Is your pre-reader paging through Goodnight Moon for the 54th time today? Wonderful. There is so much research showing repeated exposure to the same book supports fluency, automaticity, narrative expression, comprehension, and confidence at all levels of reading. Have books in every room. Like all new skills, without access to the needed tools and equipment, those new skills don’t get practiced. Stock your bedrooms, bathrooms, kitchens, and cars with books. (My family has rules about the dining room table during dinner, but that rule can bend quite quickly when someone is “at a good part.” Assess what they are filling their time with instead of reading. Do they actually have time to read? Is there ever a “down” moment that they would even be able to fill with reading? Often, lack of time is one of the biggest obstacles. If your child wants to be in every after-school class, on the travel teams, or you’re just always coming-and-going, keep books in the car. Load your playlist with audiobooks (yes, they “count” as reading). And here’s where I lose some of you: Is what they are doing instead of reading something your family values? Are they watching videos of other kids playing Minecraft? Are they doom-scrolling at the age of 7? Are they on YouTube Shorts for hours? If so, the chances of them picking up a book, which takes mental work, isn’t high. If you want to help your child love reading, you have to assess what they’re doing instead of reading. Still with me? Make reading a moment for connection. Your children idolize you. They want your attention. They want to feel close to you. Build on that desire. Read to them for as long as they will allow. I promise, your teenager wants these moments. Your three-year-old craves these moments. Make the effort to build it into your routine to read together and guard that moment with all that you have. Let them put down books they don’t like. Do you remember being forced to finish a book in school, just so that you could be quizzed on it? To tell the adult asking you to read it that yes, you’d indeed finished it against your own judgment and free will? Don’t be the one that does that to their reading enjoyment. If they don’t like a book, let them move on to the next one. Is the book they detest your childhood favorite? I see you, I feel you, I’ve been you. It stings when your daughter does NOT feel the same way about Mrs. Piggle-Wiggle as you did in second grade. Even worse when it’s From the Mixed-Up Files of Mrs. Basil E. Frankwieler. Just let them move on. It’s not worth the heartache of trying to convince them. Trust me, I know. Give them variety - and don’t talk down about their favorites. Allow them to read across a wide menu of options: graphic novels, comics, short stories, mysteries, picture books at an older age, a series that makes you want to roll your eyes. Not a fan of graphic novels or comics? Please don’t require “serious reading” before they get to something “fun.” That implies that some reading is automatically a drudgery - which will lead to avoidance altogether. Don’t overlook comics and graphic novels. Leaf through some at the library and see how they’ve evolved over the last decade. Comics are also shown to increase vocabulary, strengthen sequencing skills, and provide art education. Even better, comics and graphic novels can be a bridge for students with dyslexia, autism, and attention challenges. Don’t overlook them as a very helpful, brightly-colored tool in your reader’s toolbox! Remember - the goal is to get them reading to begin with and let them find what they love through the process. When I was a Wheaton Montessori School parent with young primary children, well before I took the AMI Elementary training, their teachers, Ms. Chiste and Mrs. Fortun, recommended “The Rights of the Reader” by Daniel Pennac during several of their parent workshops. I’d like to pass along the recommendation, as it has served my family - and teaching - for years now. Learning to love reading is a skill, just as reading itself is. Research is showing that we’re headed in the wrong direction, with just 1-in-3 public school fourth graders in Illinois reading proficiently, and college students at top universities being unable to follow or complete full books. Your chances and opportunities for “raising readers” are at-hand, so be off with you to the library! https://www.theatlantic.com/magazine/archive/2024/11/the-elite-college-students-who-cant-read-books/679945/ https://www.illinoispolicy.org/literacy-epidemic-hits-illinois-as-fewer-than-1-in-3-students-read-well/
