Montessori Basics: Geometry from the Start
April 27, 2023

Perhaps it happens one day when your four-year-old comes home from school one day, excited to show you their work for the day. They proudly show you a perfectly-traced pentagon with elaborate, colorful patterns inside that they have created.

 

Maybe it’s when your eight-year-old casually references acute-angled scalene triangles.

 

Regardless of when it happens, as Montessori parents, there comes a moment when we become acutely -aware (pun intended) of our children’s interesting knowledge of geometry. We recall our own study of the subject beginning much later – likely sometime during our high school years. We notice that our children seem to be really ready for the information, which can feel surprising. Not only are they ready, but the work seems to fill them with joy and satisfaction.

 

What, exactly, is going on?

 

As with so many things, Montessori discovered that young children are fully capable, and in fact developmentally-primed, to learn about subjects that have traditionally been reserved for much older children. Geometry is a perfect example. Read on to discover what this portion of a Montessori education can offer your child.

 

The Primary Years

From ages 3-6 much of children’s geometry instruction in Montessori classrooms is indirect. That is to say that while they are practicing crucial developmental skills, they are often doing so through the lens of geometry preparation. One obvious example, as mentioned above, is with the metal insets. Children trace a variety of geometric figures including squares, triangles, circles, curvilinear triangles, and quatrefoils, among others. The main objective of this work is to prepare the child’s muscles for proper pencil grasp and handwriting. When they have mastered tracing, they work to create intricate designs within the figure.

 

Primary students are also given a number of simple geometry lessons that allow them to begin naming figures and exploring shapes. Wooden geometric solids are held and named by the children (cube, sphere, square-based pyramid, etc.). The geometry cabinet is composed of drawers of related figures; small wooden insets are organized into a polygon drawer, curvilinear figure drawer, triangle drawer, and so on. Children also use constructive triangle boxes to manipulate triangles in order to form larger triangles and other geometric figures. The key during these early years is to give children some early exposure to geometry and allow them to use their hands to explore these concepts.

 

The Elementary Years

During the elementary years the Montessori geometry curriculum expands significantly. Teachers often begin by reviewing content taught during the primary years, but 6-year-olds are ready and eager for more. This begins with a detailed study of nomenclature.

 

Using a series of cards and booklets that correspond with lessons given by the teacher, children explore and can create their own nomenclature sets. Topics include basic concepts such as point, line, surface, and solid, but go on to teach more in-depth studies of lines, angles, plane figures, triangles, quadrilaterals, regular polygons, and circles. For example, when children learn about lines they begin by differentiating between straight and curved lines, but go on to learn concepts such as rays and line segments, positions (horizontal and vertical), relational positions of lines (parallel, divergent, perpendicular, etc.)

 

Throughout the second plane of development (ages 6-12) the study of geometry continues to spiral and go into more and more depth. Children as young as seven learn about types of angles and how to measure them. Eight year olds explore regular and irregular polygons, as well as congruency, similarity, and equivalency. In lower elementary children begin learning about perimeter, area, and volume.

 

In upper elementary, children begin to learn about the connections between the visual aspects of geometry and numerical expressions. They apply what they’ve learned about perimeter, area, and volume to measuring real-life objects – including Montessori materials they’ve seen in their classrooms since they were three years old. They learn about things like Fibonacci numbers, which combine their sense of number order with the appeal of geometric patterns.

 

Now, when your child comes home with surprising knowledge about geometry content, we hope you have a better idea of where they’re coming from. If you have any questions or would like to see this type of work in action, please give us a call.

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.
