The Benefits of Multi-age Grouping

Montessori Thrive

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.

A thriving Montessori environment is never built by educators alone. It blossoms through the partnership between school and home. In our classroom, we have already seen how family involvement enriches children’s experiences, strengthens their confidence, and fills our days with excitement and connection. This year, many of you have shared pieces of your family life with us, and those moments have made a meaningful impact. From coming in to read with the children, to supporting class events, to sending us stories of your child’s growth at home. Each gesture has helped create a sense of belonging that children can feel. When children see the adults in their world working together, they move through their day with greater ease, trust, and joy. Here are a few ways family engagement helps build our classroom community: Shared Values & Consistency at Home and School: Small routines at home such as encouraging children to dress themselves, take responsibility for their belongings, or help with food preparation mirror the independence we nurture at school. Children feel grounded when expectations are aligned. Grace, Courtesy & Respectful Communication: When families model taking turns to speak, greeting others warmly, and using kind, respectful language, children carry those same practices into their social interactions at school. Celebrating Families and Cultures: When a parent shares a family tradition, a favorite recipe, or a cultural celebration, the classroom becomes a place where every child feels seen and valued. These exchanges help children appreciate diversity and build connections with one another. One of my favorite parts of Montessori is that it is a community journey. We, as educators, are learning alongside you: observing, reflecting, and growing every day. Your questions, curiosity, and partnership inspire us to deepen our practice and support your children in meaningful ways. As we continue through the year, I invite you to stay connected in ways that feel comfortable for your family whether that means joining a classroom event, practicing independence routines at home, or simply sharing a moment of your child’s joy or success. Every bit of involvement brings richness to our shared community.  Thank you for all the ways you support our classrooms. Your presence truly makes a difference, and we are grateful to be walking this Montessori journey with you.
