The Montessori method, in plain words

Picture a four-year-old carrying a tray to a table. They pour water from one small jug into another, wipe up the drips, and then do it again. Nobody asked them to. They chose it from the shelf, and they may repeat it several times before putting the tray back.

In Montessori, that is called work. The word is deliberate. It treats what a child chooses to do as purposeful effort, worth respecting and worth finishing. Work usually follows a lesson: a guide shows a child how to use something, and the child then practices on their own. Our Elementary schedule puts it in one line: lessons are given, and follow-up work is done.

The first thing most parents notice is the room itself. Almost everything is at a child's height. Each material has one place on one shelf, and a child can take it down, use it, and put it back without asking an adult.

Montessori called this the prepared environment. Each stage of childhood is best met in a rich and carefully prepared environment, so the room is arranged on purpose rather than filled. Looking after it is part of the children's work, too. Montessorians call that care of the environment. The order on the shelves is intentional, too. Children between three and six have a strong sense of order, and a room where every material has its place speaks to it. It's why we say the room itself is a teacher. Why we build our rooms this way is the sixth of our six principles.

On the Primary shelves, the materials fall into areas, and each area has a job. Practical life is everyday work: pouring, preparing food, and caring for the room. Sensorial materials sharpen what a child notices through their senses. Mathematics materials make numbers something a child can handle. Language work covers speaking and listening, and later reading and writing. Grace and courtesy is the practice of the manners that let a group share a room.

Lessons also reach into history, geometry, biology, geology, and geography. Real things sit on our shelves beside the materials, like a geode or an owl pellet, so children study the object itself rather than a picture of it. How Primary uses all of this, year by year.

You may notice that the adults rarely stand at the front of the room. They move between children, watch closely, and sit down beside one child at a time to give a short lesson. That is why Montessori calls them guides. Behind the title is training. Our teachers are trained in the stages of development of the children they work with, so they know what to look for at three, at six, or at nine.

The title describes the job. A guide's work is to observe each child and bring them the next thing they are ready for, one lesson at a time. At South Coast Montessori you'll see the word in staff titles: Leah, for example, is our Primary Lead Guide. The role of the Montessori teacher goes deeper into what a guide does all day.

There are stretches when a child seems hungry for one particular thing and takes it in with surprising ease. Montessori called these sensitive periods: windows when a child is especially ready to learn a specific skill. Our curriculum is planned around them. Principle 02 on Why Montessori explains how.

Watch a guide teach a new word to a three-year-old and you may see three short steps. First, the guide names the thing: "This is rough. This is smooth." Next, the guide asks the child to find it: "Can you show me smooth?" Last, the guide asks the child to name it: "What is this?"

Each step asks a little more of the child. If the child stumbles at the third step, the guide knows on the spot and goes back to the second. That's the point of it. Understanding is checked while the lesson is happening, so the guide can adjust before the child moves on. Montessori calls this the three-period lesson, and it is one of the hallmarks of the method.

In a Primary room, three-year-olds work near five-year-olds, and that is by design. A Montessori classroom holds three ages, and a child stays in the same room for the whole span. This is called the three-year cycle. A child arrives as one of the youngest and leaves as one of the oldest. In Primary, that final year is the kindergarten year.

When the families who founded South Coast Montessori built the school, mixed-age classrooms and three-year cycles were among the things they were determined to keep. Our Elementary works the same way, in two stages: grades 1 to 3 and grades 4 to 6. The reasons mixed ages work are a story of their own, told in the benefits of multi-age grouping.

Three letters turn up in our teachers' training and on our website: AMI. AMI is the organization Maria Montessori created to ensure the authenticity of her method. Our wording is exact: South Coast Montessori is "dedicated to the principles of AMI (Association Montessori Internationale)."

That phrase describes how we teach and the training our guides bring. Dedication to AMI principles and AMI accreditation are two different things, and any school you visit should be able to tell you plainly which one it means. For more on judging whether a school's Montessori is authentic, see our answer on Why Montessori.

On a tour, ask the guide to show you a three-period lesson, or a piece of work waiting on a shelf. See a classroom for yourself.
