The Power And Purpose Of Montessori Materials

Montessori materials provide the student with the means of making the abstract tangible. By stimulating and engaging all the senses, these materials complete the prepared environment and support the student in the work of self-construction. To be considered a true Montessori material, it must meet specific criteria. These characteristics are reflected in the accompanying graphic.


From the moment I became a Montessori teacher, I knew the materials were both inspired and inspiring. They immediately felt purposeful, and each one clearly designed to support a student’s thinking and independence. The depth of thought embedded in each one continues to amaze me, even after years of working with them. I have spent 15 years as an Upper Elementary teacher and am now in my fourth year in Lower Elementary, and I am still making new connections between the materials and concepts I once encountered in my own traditional education.


For example, I learned long ago that an isosceles triangle has two equal sides. What I did not fully realize until becoming a Montessori teacher is that it also has two equal angles. The Pythagorean Theorem finally made sense. Why a negative times a negative equals a positive was no longer just a memorized fact. That deeper understanding came not from memorization, but from hands-on exploration. Over time, I have also gained a strong appreciation for the intentional flow of the materials; how one material carefully prepares the student for the next in the sequence. Concepts are revisited and deepened through multiple representations. Multiplication, for instance, can be explored through the Golden Beads, the Stamp Game, the Checkerboard, or the Bead Frame as well as the Bank Game and the Golden Bead Frame. If one material does not resonate with a student, another often will.



I also love the continuity that exists across the materials. The hierarchical colors in mathematics (green for units, blue for tens, and red for hundreds) remain consistent from Primary through Middle School and across the hierarchical families (simple, thousands, millions, and beyond). This consistency provides students with a powerful internal framework that grows with them over time. With experience, teachers also come to see how a single material can support multiple concepts. Fraction Circles, for example, can later be used to explore the measurement of angles in degrees.


One of the most important understandings for new Montessori teachers is recognizing that the materials are not tools for the teacher to teach, but tools for the student to learn. The materials belong to the students. This can be challenging at first, especially when a beautiful, brand-new material is placed into the hands of a student, knowing it may never look "new" again. Montessori materials are expensive, and students can be tough on them. Over the years, I have learned to make peace with this reality. My go-to phrase when I notice a bit of wear and tear has become: “That is a well-loved material.”


The materials were designed to guide students toward self-discovery, if only we adults have the patience to allow that process to unfold. Even after nearly 20 years in the classroom, the materials still have something to teach me. There are moments when a student notices something in a material that I had never seen before, and we share that excitement together. I still experience genuine “aha” moments.


I am continually fascinated by how precisely the materials align with a student’s sensitive periods. As Dr. Maria Montessori wrote, “The hands are the instruments of man’s intelligence,” and nowhere is this more evident than in the thoughtful design of the Montessori materials. In Primary, many materials support the student’s deep need for order. In Elementary, the materials appeal to intellectual curiosity and imagination. Some materials even span multiple planes of development. A material may be introduced in Primary for one purpose, revisited in Lower Elementary for another, and expanded again in Upper Elementary to inspire higher-level thinking. Our bead cabinet is one such material.


I began my Montessori career as an assistant in a UE classroom in Ohio, and my mentor told me I was not allowed to “play” with the materials; they were not toys. She explained that if I wanted to learn how to do Test Tube Division, I would need to be trained. So, I did. That path eventually led me not only into the classroom, but also into teacher education. Each summer, I have the privilege of working with new teachers as a credentialed AMS Montessori instructor, supporting them as they begin to understand the depth, purpose, and responsibility that comes with guiding students through these materials. It remains the best career decision I have ever made!!

Maria Montessori based her entire educational philosophy on the idea that children developed through a series of four planes. Each of these planes is easy to recognize and has clear, defining characteristics. If we study and understand these stages, we can approach our interactions with children with a new perspective.

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.
