The Benefits of Multi-age Grouping
Alison Petersen • October 25, 2023

One hallmark of a Montessori education is the use of multi-age classrooms. 


Infants and toddlers may be together or separate, with a toddler classroom serving children 18 months to three years. Primary classrooms are for children ages 3-6, with preschool and kindergarten-aged children together. The elementary years serve children ages 6-12; some schools separate into lower (6-9) and upper (9-12) elementary, while many split elementary into two groups. Even Montessori middle- and high-school students learn in multi-age classrooms.


While Montessori is not the only type of education that utilizes this approach, it’s not what most people are used to. What are the benefits of structuring a classroom this way? Read on to learn more...


Learning at an Individual Pace


Children in multi-age classrooms tend to have a little more flexibility when it comes to mastering skills within a specific timeframe. We know that learning is not linear, and that learners have periods of significant growth, plateaus, and even the occasional regression. In multi-age classrooms, children are typically able to work at their own pace without the added pressure of keeping up with the whole group, or even being held back by the whole group. 


When children in a classroom range in ages, everyone has someone they can work with, regardless of their skill level. Children don’t feel left behind if they struggle with a concept, and they also don’t feel bored by repetition of something they have already mastered. Teachers who teach in multi-age classrooms typically have deep knowledge for a range of developmental abilities, leaving them well-equipped to differentiate instruction for each individual child.


Building Stronger Relationships


Traditionally children move from one class to the next each year. This means not only a new set of academic expectations, different routines, and different classroom structures, but a different teacher. 


In multi-age classrooms teachers have a longer period of time to get to know a student and their family, and vice versa. When teachers really get to know a student, they are able to tailor instruction in regards to both content and delivery. They know how to hook a specific child onto a topic or into a lesson. They know what kind of environment a child needs to feel successful.


Parents have an opportunity to get to know teachers better this way, too. If your child has the same teacher for two or three years, the lines of communication are strengthened. Parents get to know the teacher’s style and expectations. The home to school connection becomes more seamless, and the biggest beneficiary is the child.


Mentors and Leaders


When a child spends multiple years in the same class they are afforded two very special opportunities. 


Children who are new to the class are fortunate enough to be surrounded by helpful peer mentors. Children often learn best from one another, and they seek to do so naturally. First and second year students watch as the older children enjoy advanced, challenging work, and this inspires them. They look to the older children for guidance, and the older children are happy to provide it. 


After a year or two in the same room, students have a chance to practice leadership skills. In Montessori classrooms, the older children are often seen giving lessons, helping to clean up spills, or reaching out a comforting hand to their younger friends.


The best part is kids make the transition from observer to leader in their own time. It doesn’t happen for all children at the same time, but when it does it’s pretty magical to observe. 


Mirroring Real-Life


There is no other area in life in which people are split into groups with others who are exactly their chronological age. Whether in the family, the workforce or elsewhere, people ultimately need to coexist with people older and younger than themselves. Doing so makes for a more enriching environment, replete with a variety of ideas and skills. 


Why not start the experience with young children in school?


Moving On


While staying in the same class for multiple school years has many benefits, a child will eventually transition into a new class. While this can feel bittersweet (for everyone involved!) children are typically ready when it is time.


The Montessori approach is always considering what is most supportive of children depending on their development. When formulating how to divide children into groupings, Maria Montessori relied on her ideas about the Planes of Development. There are very distinctive growth milestones children tend to reach at about age 3, another set around age 6, and yet another at age 12. The groupings in our schools are intentional, and they give kids a chance to feel comfortable in their community, while also preparing them to soar forward when the time is right.

This post is for the primary families (although the families of older students who read it will readily agree and support the points below – ask them when you have a chance!). Some of you were originally drawn to Montessori because you’ve read about how different and special the approach is. Some of you were looking for a high-quality daycare or preschool and stumbled upon us. There are a plethora of reasons families choose to send their children to Montessori schools. The vast majority of those families are thrilled with their decision once they see how their child is nurtured, encouraged, and celebrated in our environments. Something interesting tends to happen sometime around when the child approaches kindergarten and first grade. Families feel the pull of traditional schooling. They begin to worry that the differences that make Montessori so wonderful just won’t cut it when it comes to preparing their older child for life. They may have excellent public school options available to them. It can be hard to go against what you did as a child, or what your family or friends are doing for their children. And we fully recognize that the decision is incredibly personal. What we can tell you is that many families who choose to leave Montessori before their child enters kindergarten end up returning. We can also tell you the three-year cycles in our environments are intentional, and there are some great reasons to give your child the gift of that third year. Feeling on the fence? Hopefully we can help clarify some of the reasons we think kids do best when they have the opportunity to complete their primary cycle. Mastery of Skills The third year in a Children's House classroom is a chance for students to really shine academically. Everything they have been working on comes full circle and their understanding of concepts solidifies in a way it couldn’t have until now. Much of what we teach in the earlier years of our primary environments is indirect and direct preparation for the lessons our third years receive and the materials they work with. Not only are our kindergarten children understanding concepts in new ways, but they can actually demonstrate this knowledge. Educators from all backgrounds will agree that when a person is able to teach someone a skill, they have themselves demonstrated mastery of the skill. Our classrooms are designed so that older students help to teach younger ones. This teaching serves multiple purposes, one of which is to demonstrate their own understanding. One of the many benefits of the multi-age classroom, our kindergarteners really enjoy taking on the role of giving lessons to their younger peers. Opportunities for Leadership Teaching lessons to younger children isn’t just about academic mastery; it’s also a chance for kids to experience leadership. We believe that solid leadership isn’t really about power. It’s about allowing those with experience to take on a role of guiding others with less experience. So much of this type of leadership is done by modeling, and our kindergartners serve as the very best models for our younger students. When your child first entered the classroom, they went through a period in which they needed to figure out expectations, routines, and so much more. Children need to learn how to be independent, how to interact with one another and adults, how to care for the environment, and so on. As adults who guide the children, we model and verbalize what children need to learn, but we are wise enough to recognize that they learn more from watching their peers. Older children relish in this opportunity. It feels good to know that you are helping someone else. It feels good to acknowledge how far you have come, and how you are now able to guide others along their own path. Our third years know about this role because we discuss it with them often. By the time they step into it, they are more than prepared. Continued Respect for Individuality You already know that Montessori schools respect each child’s individual path, and that we believe even young people deserve to be treated with dignity. There are many ways in which we differ from conventional institutions, but some that we think are important to highlight are: Allowing the child to use the restroom when they need to, without having to ask permission from an adult Encouraging children to eat a snack when they are hungry and drink when they feel thirsty Creating a structure that allows children to take breaks when they need to, and to focus deeply on their work for long periods of time without being interrupted Giving children academic choice within limits (they may be required to complete certain tasks, but it’s okay if they choose the order in which the tasks are done) Creating flexible seating choices so that children have options to sit alone or with friends, in a chair or on the floor Advanced Academic Expectations Parents in our community often recognize that our curriculum tends to exceed the scope of what is taught elsewhere. We do not push children to learn what is beyond their capabilities, we just know that children are capable of more than most people realize. When given the opportunity, they can amaze us all. We honor the fact that every single child develops at their own rate, and there is no set time for various skills to be mastered. It is not uncommon, however, for Montessori students to: Be reading before they enter kindergarten Be working with numbers into the thousands at age four Have an understanding of basic grammatical principles at age five Engage with basic geometry concepts not typically introduced until years later Enjoy skills and content taught in the areas of biology and geography beginning at age three Learn cursive handwriting before entering elementary school Begin adding large numbers and have a basic understanding of exchanging for tens Deep-Dives Into Areas of Personal Interest One of the best parts of being in a Montessori classroom is being allowed the time to explore one’s own interests. Because of the flexible nature of the day, kids can practice various skills while learning about what creates a spark for them. Are they into dinosaurs? We provide books, paper, and art supplies for them to write about and draw diagrams of these ancient creatures. Are they proud of their family’s culture and heritage? We make space for children and families to give presentations and share their traditions. Do they dream about being a vet as an adult? Older children may be given more responsibilities to care for class pets, and they often find creative ways to connect the zoology curriculum to the animals they know and love in real life. In a Montessori classroom, the possibilities really are endless. The experience is unlike anything that can be found in other educational settings, and each year we can give our children a Montessori education is a gift. Still have questions? Please don’t hesitate to reach out and let us know how we can support you and your child.
