The Capstone Years
March 7, 2024

Age 6 and age 12 in Montessori are referred to as the capstone years. During these years children really dive into big work and develop their self-confidence.

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. Two significant times of change for young people are around age six and then again around age twelve, the kindergarten and 6th-grade 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 own self-construction, but not actually do it for children. Children are able to accomplish self-construction through their own activity 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 are moving from infancy into childhood, and similarly, around age twelve they move from childhood into adolescence.



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 that happen 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 start to become leaner and lanky. Similarly, our twelve-year-old’s are on the brink of adolescence, another period of dramatic physical growth and change.


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-old’s. Often children at these ages are moved too quickly into an environment that both 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


In Montessori, we recognize the importance of these transitional years and intentionally design our learning communities to support young people during this time. The six-year-olds and twelve-year-old’s are the oldest in their classroom learning communities. 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- and twelve-year-old’s 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 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 young six-year-old and twelve-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 their ability to successfully navigate the bigger projects that were beyond their capabilities in the earlier years. Plus, they do so in a community of adults and peers who have shared in their learning experience 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. We invite you to visit our classrooms, so you can see for yourself the significance of these capstone years.

Dear MSLF Community, After over 20 years of teaching Lower Elementary students at MSLF, Kathryn Jasinski has shared her plans to retire from teaching at the end of the current school year. There is no doubt about the impact Miss Jasinski has had on our school community during her long tenure here. Kathryn has been well known for her dedication to her students, to developing the whole child, and for her passion for Montessori education, always staying true to the core tenets of Montessori philosophy. Her legacy at MSLF will certainly live on in each of the students who have been lucky enough to have been in her class and in the many words of wisdom she has shared with her fellow colleagues, past and present. No doubt each one of her current or former students who receives a note from her in the mail instantly recognizes her perfect cursive writing and the thoughtful note inside. Kathryn’s care of her students extends well beyond their time in her classroom as she has kept in touch with dozens of her former students and has even welcomed some back to work alongside her as assistants. She has been a mentor to many, imparting her years of expertise on all those who have had the privilege of working with her. While we are sad to see her go, we know that she will enjoy her well-earned retirement, and we look forward to celebrating Kathryn’s legacy more this year. MSLF is pleased to announce that Laura Earls will be the new Lower Elementary lead teacher for the 2025-26 school year. Laura has been co-teaching in our Upper Elementary classroom since the beginning of the current school year. Laura Earls joined the MSLF team from Higher Ground Education where she was Regional Program Lead, working to elevate program quality in all Guidepost Montessori schools across the Chicago area. It was during this work that she realized how much she missed working directly with children in the Montessori classroom and decided to return to teaching. Laura received her BA in art history from the University of Dallas and completed graduate work at the University of Notre Dame. Soon after, Laura shifted her career to education and earned her AMI Elementary Montessori Certification (6-12 years old) at the Montessori Institute of Milwaukee. She then taught in an Elementary classroom at Forest Bluff School, and her classroom was profiled in Paula Polk Lillard’s book, Montessori Today. After moving to Wisconsin to raise her three children, Laura received her AMI Primary Montessori Certification (3-6 years old) at the Midwest Montessori Institute. After that, she worked as a Primary Directress and Director of Admissions at a Montessori school in Wisconsin, as Head of School of Forest Bluff School, and as Senior Head of School at Guidepost Montessori. Laura has three grown children who all experienced Montessori education themselves and are thriving in college and beyond. Laura has lived and studied in both Paris and Rome and is an accomplished pianist. Laura is excited to make the transition to the Lower Elementary classroom and looks forward to working closely with current and new Lower Elementary families next year. She also looks forward to meeting families in the Lower Elementary classroom during the Open House on February 5. With Laura transitioning to the Lower Elementary classroom following the current school year, MSLF will be conducting a search for a new co-teacher to work alongside Debbie Lincoln in the Upper Elementary classroom for the 2025-26 school year. We are thankful to Laura for all the support she has offered the Upper Elementary community this year. Please join me in wishing Kathryn a peaceful and fulfilling retirement and in welcoming Laura to the Lower Elementary community. Sincerely, Hope Allegretti Head of School - Executive Director Montessori School of Lake Forest
