The Montessori Method

An Education Built on How Children Grow

Before you choose a program, it helps to understand the method behind every AIA classroom, one built on more than a century of observing how children actually learn.

A Bit of History

Developed by an Italian physician who watched, before she taught.

Dr. Maria Montessori was an Italian physician and educator who, in the early 1900s, began developing her method through careful scientific observation of how children naturally learn, concentrate, and grow. Rather than starting with a curriculum and asking children to adapt to it, she built an approach around the child, observing what genuinely captured their attention and designing hands-on materials and environments around it.

More than 100 years later, that same foundation, respect for the child, hands-on discovery, and learning at an individual pace, still shapes every AIA classroom, from our youngest 18-month-old learners through our 8th grade Middle School students.

The Five Pillars

What makes a classroom Montessori.

The thousand chain: counting to 1,000 bead by bead, until big numbers aren’t abstract at all.

The Prepared Environment

Every material has a home, sized and placed for the child, encouraging independence from the moment they walk in.

Hands-On Materials

Carefully designed materials allow children to experience abstract ideas concretely, supporting understanding before and alongside symbolic and verbal work.

Multi-Age Classrooms

Three-year age spans let younger children learn by watching older peers, and older children deepen understanding by mentoring.

Uninterrupted Work Time

Long, unhurried work periods let children follow their own curiosity to real depth and concentration.

Respect for the Child

Guides observe before they intervene, treating every child as a capable, curious individual, not a student to be managed.

“The essence of independence is to be able to do something for one's self.”
– Maria Montessori, The Absorbent Mind (1949)
