The Mixed-Aged Classroom

There are many elements that make Montessori education stand apart from more conventional methods. One of the most obvious is our mixed-age classrooms. Rather than group children by a single chronological age, our classrooms span across multiple ages, and the benefits are numerous and lasting.

How we break it down

A Montessori school doesn’t place a 3-year-old in the same classroom as a twelve-year-old (although we do love to find opportunities for children to work together from different periods of growth and development!). Generally speaking, the classrooms take on three-year age spans that correspond with the natural planes of development.

  • Toddler – Children aged 0-3 have specific (and similar) developmental needs. Our Toddler program includes ages 16 months-3 years.
  • Children’s House/Primary – We combine what is traditionally called preschool and kindergarten into a single classroom, with children ages 3-6 working alongside one another.
  • Elementary – We have a Lower Elementary (ages 6-9 years) and an Upper Elementary (9-12 years) environment.
  • Middle School – In September of 2024 we will continue our mixed ages by combining 7th and 8th grade on our 12-acre Milwaukie Campus.

We find this method of mixed-ages to be extremely beneficial. There are so many perks to having multiple ages in the same classroom environment. Here are just a few:

Models and leaders

By having children of different ages together in one room, the younger children enter the environment with a variety of older children that serve as models to them. It is often the case that children learn best from one another, and when a 6-year-old watches an 8-year-old work, they quickly understand what is expected and what kind of work lies ahead in their future. As for the older children in the class, they have many opportunities to serve in leadership roles, and cultivate the skills that are critical to become independent members of their communities.

Enhanced social opportunities

Diversity is important on all levels, and that includes spending time with people of different ages. We have so much to learn from each other, and children gain all sorts of skills from their interactions in a mixed-age classroom, like empathy, patience, and open-mindedness.

Fluid Skill Progression

Learning is not linear, for any of us. There are periods of rapid growth, periods of steady progress, and times spent in plateau. This is normal and will vary across subject areas for individual children. This is why we don’t believe it makes sense to deliver a prescribed curriculum to all students at the same time, ultimately leaving some children bored and others struggling. In our classrooms, kids can work and progress at their own rates, while learning from each other.

Strong relationships

When a child is in a class for three years, it allows the guide to really get to know them, not just as a learner, but as a person. Rather than starting from scratch each September, the child-teacher-parent team is already established and can work together on a deeper level, and with greater understanding of strengths and goals, than they would otherwise be able to.

Reflection of real life

We would be hard-pressed to find an example outside of conventional schools, in which people are sorted into one-year age groups and told to spend most of their day together. Multi-age classrooms are a much better approximation of what life is really like, and children benefit from these early experiences.

What did Dr. Montessori have to say about it?

Maria Montessori had a way with words. While she was a woman of science who relied heavily on her observations, her descriptions and explanations often captured the hearts of her audience. Her discussion of the multi-age classroom was no different.

“Our schools have shown how children of different ages help one another. The younger ones watch what the older ones are doing and ask all kinds of questions, and the older ones explain. This is really useful teaching, for the way that a five year old interprets and explains things is so much nearer than ours to the mind of a child of three, that the little one learns easily, whereas we would scarcely be able to get through to him. There is harmony and communication between them that is not possible between an adult and such a young child. There is a natural mental osmosis between them. A child of three is also quite capable of taking an interest in the work of a five year old, because in fact the difference in their abilities is not that great.

“People are concerned about whether a child of five who is always helping other children will make sufficient progress himself. But, firstly, he doesn’t spend his whole time teaching, but has his own freedom and knows how to use it. Secondly, teaching really allows him to consolidate and strengthen his own knowledge, which he must analyze and use anew each time, so that he comes to see everything with greater clarity. The older child also gains from this exchange.”
