THE BENEFITS OF THE MULTI-AGE GROUPING
September 13, 2024

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.

Since the pandemic, we can find ourselves carrying new or heightened worries about our children’s social lives. We can have concerns about whether our children “lost time” with peers during critical developmental years. Or maybe it’s worry about shyness, reluctance in groups, or how screen time may have replaced face-to-face play. Even now, long after schools and activities have reopened, it’s common for anxiety to surface: Is my child making enough friends? Are they socially behind? Why We Feel This Way The truth is, these concerns are natural. COVID disrupted our social connections, and children being with other children is an important part of childhood. For months (and for some even years), daily opportunities to share space, work through conflict, and experience the joy of play were limited. Add in the reality of increased screen use, the culture of comparison amplified by social media, and children who may show hesitations around groups, and it’s easy to see why we are carrying this extra layer of worry. What Montessori Reminds Us Montessori provides us with a helpful perspective: growth is not lost, it is simply unfolding in its own time. Children are incredibly resilient. Social development isn’t a race, and there isn’t one perfect timeline. Just as each child learns to walk or read at their own pace, children find their own paths into friendships and community life. How We Can Support Children (and Ourselves) So, what can we do to ease our own (and our children’s) anxiety while supporting their social growth? First, remember that depth of connection matters more than numbers. A child with one or two genuine friendships has a strong foundation. In Montessori classrooms, we often see that meaningful, sustained interactions carry more value than a large peer group. Second, provide opportunities for natural interaction rather than overscheduling. Time at the park, family gatherings, or small playdates often offer more authentic growth than tightly managed activities. In the classroom, children practice collaboration daily, from sharing materials to working on group projects. Third, support independence. After COVID, it’s natural to want to step in quickly if our child seems uncomfortable socially. But small moments of trust—like letting our children introduce themselves, ask to join a game, or resolve a conflict—help them build confidence and resilience. Finally, model calm and social grace. Children absorb how we approach social situations. When they see adults showing openness and curiosity, they are more likely to approach peers with the same ease. Partnering with Teachers Your child’s teacher is also a valuable partner. Montessori guides closely observe children’s social interactions and can offer concrete reassurance: “I noticed your child inviting a friend to join her work,” or “He showed patience while sharing materials today.” These insights often show growth that may not be as apparent outside the classroom. Supporting Social Growth at Home Simple, practical activities in our children’s lives can make a big difference. Hosting a “work together” playdate, for instance, shifts the focus from entertainment to shared purpose. Children might bake bread, build with blocks, or create art together. These collaborative activities naturally encourage conversation, cooperation, and problem-solving, giving children structured opportunities to navigate relationships. Practicing grace and courtesy at home also builds confidence. Small role-plays, like how to join a game or politely declining an invitation, help children learn the social scripts they need. Learning how to insert themselves into play: “What are you playing? I’ll join too!” or “No, thank you. I’d like to work alone right now,” are examples that may seem small but make a significant difference when children encounter peers in real settings. Family game nights are another excellent tool. Cooperative board games, memory games, or card games teach turn-taking, handling winning and losing, and joyful connection. Games provide low-stakes opportunities to practice critical social skills like patience, negotiation, and flexibility. Finally, spending time in community spaces offers invaluable real-world practice. Visits to the library, farmers’ market, or nature center allow children to engage in everyday interactions, such as greeting a librarian, asking a vendor a question, or navigating shared space with peers. These experiences help children build confidence and fluency in social settings. Moving Forward with Confidence It’s understandable to feel anxious about our child’s social life after such a collective disruption. But rest assured: children are not permanently “behind.” With trust, time, and supportive environments, children continue developing the skills of friendship, collaboration, and community. Montessori reminds us that growth is steady and ongoing. Our role is to provide the space, opportunity, and confidence children need to thrive socially. When we step back and trust the process, we discover that children are, in fact, developing social competence.
