The Benefits of Multi-age Grouping
Montessori Thrive • June 1, 2021

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.

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.
