Power & Potential: The Sensitive Periods

Tamara Sevigny • December 12, 2022

Have you ever noticed how sensitive young children can be to changes in routine? Even the slightest schedule adjustment can throw things off. On the positive side, young children also have an incredible ability to internalize the order of their daily activities. They intuitively know when something is supposed to happen during a regular day.

It’s also pretty amazing how quickly young children absorb the intricacies of language, how they progress so seamlessly from sitting to crawling to walking to running, or how they can be so focused on tiny details and objects.

During these times in their lives, children seem to be compelled by an irresistible force. Think of the little one who wants to climb up the steps again and again. We can try to stop them, but they are undeterred! And despite the great effort involved, the activity almost seems effortless to them.

In Montessori, we pay close attention to these periods of time when children show intense focus on mastering a new skill, creating deep understanding, or refining their abilities. We call these times “sensitive periods.”

What are Sensitive Periods?

To paint the picture of sensitive periods, Dr. Maria Montessori used the example of newly hatched caterpillars. These young caterpillars hatch from eggs in protected nooks but are drawn toward the light where they can eat soft, young leaves at the ends of branches. The young caterpillars aren’t aware of the fact that going toward light will provide them with a food source. Rather, they are responding to a biological impetus. Once that need is satisfied, the caterpillars no longer have the desire to move toward bright light. That sensitive period is over and they shift into the next stage of their development.

Like the young caterpillars, young children in a sensitive period become incredibly absorbed with acquiring or mastering a new skill and hone in on the activity that aids their development. Neurologically, this is the time when groups of neurons become more active than others and establish key neural networks in children’s developing brains. These windows of opportunity are transitory and marked by children’s passionate focus on mastering a skill or characteristic.

In Montessori we focus on four main sensitive periods:

Order
Language
Refinement of the Senses
Movement

Sensitive Period for Order

The sensitive period for order is most intense from birth to three years of age, although it does continue through age six. When children are under the influence of the sensitive period for order, we see their intense interest in the order of things, both in routines (time, order of events in day, etc.) and in their environment. Young children can show great distress if this order changes.

As adults, we can appreciate that order makes our lives easier; planning our meals and picking out clothes ahead of time makes our week flow more smoothly. Organization and order are a convenience and make us more efficient. But young children need orderly environments in a different way. The order in their surroundings or routines becomes the basis for their relationship with the world. If that foundation of order is changing all the time, it’s like trying to build a house on a shifting foundation. Lots of changes in the environment or schedule cause children to have to constantly adapt, which diverts their energy away from other necessary forms of their development. When children have a predictable and ordered environment, they feel secure, trust their environment, and establish an internal order.

Sensitive Period for Language

Children are effortlessly absorbing language from birth. The first three years of life are focused on the development of spoken language and the last three years are focused on the expansion and refinement of language, including writing and reading. During this sensitive period, children are learning the intricacies of the language spoken around them. They hear sounds and begin to try to imitate them. They hear the rhythm of phrases and sentences. They begin to internalize the nuances of grammar.

Because children are absorbing all aspects of language, they need rich language experiences. Thus, we want to provide lots and lots of vocabulary by naming real things in the environment and engaging in meaningful conversation, even with our infants!

Sensitive Period for Refinement of the Senses

Young children are learning about their world through sensory experiences. The sensitive period for refinement of sensory perceptions starts at birth and begins to fade around four and a half.

This sensitive period does not make children’s eyes see better, ears hear better, or tongue taste better, but it does help children distinguish between finer and finer differences. Children who have access to sensorially rich environments can begin to refine their senses, have clearer perceptions, and be able to organize and classify their impressions. Neurologically, this sensitive period is when children are creating neural networks that help them interpret their environment through visual, auditory, olfactory, gustatory, and tactile perceptions. An enriched experience gives children the opportunity to develop powers of sensory discrimination, like perfect pitch, that will last throughout a lifetime.

Sensitive Period for Movement

Movement is how children come into contact with their environment, express their developing personality, and develop their independence. So much movement development happens from birth, and then, from about ages two and a half to four, children focus on refining their movements.

Children in this sensitive period benefit from having their movements directed toward some purposeful aim. For example, children want to imitate and participate in daily life, like cooking and preparing food. As parents, we often give our children play kitchens. With no other options, children will play with the pretend kitchen for a while, but this doesn’t satisfy them for long. They are much happier preparing real food for themselves and those around them. Meaningful activity, like food preparation, helps children refine their movement, adapt to their culture, and contribute to their community in a purposeful way.

Power & Potential

Although “sensitive periods” refer to the particular times when children are most open to developing a particular skill or trait, the name is a profound reminder. We need to be sensitive–treading mindfully and with great care–to the power and potential of these periods of development.

During the sensitive periods, children develop the skills and characteristics of order, language, refinement of the senses, and development and refinement of movement without apparent effort. Once the sensitive periods have faded, children can still achieve and develop certain characteristics, but they have to do so using work and effort. Plus, the skill or characteristic isn’t as fully integrated and absorbed. Think about how hard it is to learn a second language as an adult!

Most delightfully, when children are in a sensitive period and their needs are met, they experience deep inner joy and a sense of satisfaction. We invite you to schedule a tour by clicking here so you can come visit our school and see this joy and satisfaction in action!

The Quiet Landing: Why Children Need Time After School

By Danielle Giordano • February 10, 2026

When we pick up our children from school, it’s almost automatic to ask, “How was your day?” And just as automatically, the answers tend to fall flat: fine, good, okay, or sometimes nothing at all. As adults, we can probably relate. When someone asks about our day, we don’t always feel like revisiting every detail, especially before we’ve had a chance to rest or reset. For children, this challenge is even greater. In Montessori environments, children are immersed in experiences that are rich, complex, and often difficult to put into words. How does a young child explain the sensorial experience of carefully carrying each cube of the Pink Tower across the room? Or describe the quiet satisfaction of discovering that ten tens create a hundred square? Or articulate the subtle social negotiations that happen during community lunch? Even for older children, language often lags behind experience. Why “How Was Your Day?” Can Feel Like Too Much As children move into the elementary years, they are also navigating peer relationships that are still very black and white. A single interaction can color their entire perception of the day. So their reports may sound overly simple: someone was mean, someone was nice, the day was bad, the day was good. But often, the issue isn’t that children don’t want to share. Instead, the timing is off. Research on children’s nervous systems helps explain why. When children walk out of school, their brains are often still in a state of high alert. Throughout the day they’ve managed noise, social expectations, concentration, corrections, and constant stimulation. Their nervous system hasn’t fully shifted out of “school mode” yet. So it helps if we remember that we aren’t greeting children in their most rational state. Those first minutes after pickup are a transition, not a conversation window. When we jump in with questions too quickly, even well-meaning ones, we may unintentionally overwhelm our children’s nervous system, which hasn’t had time to settle. Connection Before Conversation In Montessori, we place great importance on transitions. We know children need time to move from one state of being to another, whether that’s arriving at school, moving between activities, or going home at the end of the day. Instead of starting with questions, we can start with presence. When we first see our children, a warm greeting that communicates “I’m happy to see you” goes a long way. Some children need a snack. Some need quiet. Some need movement, proximity, or simply space. This is not the moment to gather information. This is the moment to re-establish connection. When families allow even 10 to 12 minutes of quiet decompression after school, through silence, music, or simply being together, children regulate more quickly. Evening stress decreases, cooperation improves, and children are more likely to talk voluntarily later on. Rather than interrogating right after school. Try coexisting. This pause is deeply respectful. When Children Are Ready to Talk Later, after your child has had time to settle back into your care, you may notice that conversation begins naturally. This is often when children share what mattered most to them, not what we might have thought to ask about. When you do open the door to conversation, gentle specificity helps. Broad questions like “How was your day?” can feel overwhelming. Instead, try comments that invite reflection without pressure: “I noticed you seemed really focused when I picked you up.” “I’m here if you want to tell me about something you worked on today.” “What felt good about today?” Just as important as the words is our availability. Putting down the phone, pausing the logistics, and showing with our body language that we are truly listening makes it safer for children to share. Listening for Timing, Not Just Content This approach applies across ages. Even adolescents benefit from what some call a “quiet landing” after school. When we honor timing, we’re less likely to walk into the emotional residue of the day and more likely to build cooperation and connection later. In Montessori, we often say: regulation comes before reflection. Children don’t need us to extract their feelings. They need us to create the conditions where feelings can land safely. Sometimes that looks like silence. Sometimes it looks like presence. And sometimes, after enough space has been given, it looks like a child finally saying exactly what mattered most. So the question isn’t just “Do I listen to what my child says?” And instead becomes: “Do I listen for when they’re ready to speak?” Curious to learn more strategies to support your child during transitions?

Elementary Story: How Geometry Got Its Name

By Danielle Giordano • January 30, 2026

In Montessori elementary classrooms, we like to introduce big ideas with big stories. We offer children a sense of wonder first, sort of like an imaginative doorway, so that when they later study formulas, theorems, and proofs, they already feel connected to the human story behind them. One of these stories is The Story of How Geometry Got Its Name, an introduction to a subject that is far older than the textbooks and protractors we encounter today. In Montessori, Geometry is more than about shapes. It is about human beings solving real problems in the real world. A Problem as Old as Civilization To introduce geometry, we take children about five thousand years back in time to the ancient civilization of Egypt. This was a land shaped by the , the longest river in the world. Each year, the Nile flooded its banks as snowmelt poured down from the mountains far to the south. The Egyptians depended on this yearly flood as it left behind rich, dark silt that nourished their crops and made life possible in an otherwise harsh desert. But the flood created a challenge, too. It washed away the boundary markers that separated one farmer’s field from another. When the waters receded, no one could quite remember where their land began and ended. Arguments ensued. “This corner is mine!” And the fields needed to be measured and marked again. The First Geometers: The Rope Stretchers To solve this annual problem, the Egyptians relied on a special group of skilled workers called the Harpedonaptai, or Rope Stretchers. These were early land surveyors who used a knotted rope tied at regular intervals and three weights to create a very particular triangle. In the classroom, we invite a few children to hold a prepared rope at its large knots, forming that same triangle. As they stretch it out and lay it on the ground, many quickly recognize what the Egyptians had unknowingly created: a scalene right-angled triangle. This shape would later become central to the geometry studied by Greek mathematicians. The Rope Stretchers used this simple tool to re-establish field boundaries, set right angles, and make sure the land was measured accurately and fairly. Geometry, in its earliest form, served a deeply practical purpose. From Rope to Pyramid The Rope Stretchers’ expertise was valued far beyond the farmlands. They also helped lay out the foundations of temples, monuments, and even the Great Pyramid of Giza. The base of the Great Pyramid is a perfect square, which is an astonishing feat of measurement and design. The Pharaoh himself oversaw these measurements, but it was the Rope Stretchers who executed them. Their work represents one of humanity’s earliest recorded sciences: the careful measuring of the earth. How Geometry Got Its Name The name geometry reflects this ancient practice. It comes from two Greek words: gê — earth metron — measure Geometry literally means earth measurement. The Egyptians did not use the language of right angles, nor did they classify triangles as we do today. Their work was grounded in practical needs. They needed to solve problems, organize land, and create structures that would endure for thousands of years. Yet their discoveries influenced later thinkers like Pythagoras, who likely traveled to Egypt and learned from their methods. Over time, the simple knotted rope inspired a whole discipline devoted to understanding lines, angles, shapes, and the relationships between them. Why We Tell This Story in Montessori When Montessori children hear this story, something important happens. Geometry becomes more than a set of rules or vocabulary words. It becomes a human endeavor born from curiosity, necessity, and ingenuity. This is the heart of Montessori’s cosmic education: helping children see knowledge not as isolated subjects, but as gifts from generations before them. When children pick up a ruler, explore angles with a protractor, or classify triangles in the classroom, they are continuing a legacy that began with those early Rope Stretchers on the banks of the Nile. Through story, children feel connected to the people who shaped our world and to the problems that inspired great ideas.
