An Explosion in Language Development

Meagan Ledendecker • February 10, 2025

Almost 120 years ago, when Dr. Maria Montessori created the first Children’s Houses in the slums of Rome, she saw a curious phenomenon. Young children, who not that long before had been considered street urchins, developed a sense of pride in their work and soon were eager to read and write. In fact, Dr. Montessori tells a story about how the children and their parents begged her to teach them writing and reading, despite the fact that, at the time society didn’t think that children under six were capable of this type of learning.

 

Then Dr. Montessori did what she did so well: she observed the children, she identified what skills they needed, and she provided opportunities for the children to develop. The result? Dr. Montessori saw what she described as an “explosion” into writing and reading.

 

In Montessori, we support children’s progression (and “explosion”!) in three aspects of language development: spoken language, written expression, and interpretive reading.

 

Spoken Language

 

Because spoken language is the foundation for all work in the language area, we offer rich, full, and beautiful language for young children through a variety of activities to cultivate conversation skills. Our enrichment of vocabulary exercises focus directly on expanding children’s receptive vocabularies and cultivating children’s experience and intelligence. As we engage children in language games, we also help increase their listening skills as well as their comprehension. As part of spoken language development, we also take the time to listen to children’s own spontaneous efforts of expression, so that they gain confidence in speaking and feel that their thoughts have meaning.

 

Written Expression

 

The act of writing consists of two separate elements: composing and recording. Composing is the mental work–thinking about what to say. Recording is the physical aspect of writing. In the Children’s House, we prepare these two elements separately by offering exercises to prepare the hand for recording and exercises to prepare the mind for composing. Writing is having a known thought that goes from sound to symbol, a process that is much easier than the process of reading.

 

Because the development of the hand takes longer than the development of the mind, we use a material called the movable alphabet as a way for children to compose words before their hands are ready to write. The movable alphabet is a box containing the letters of the alphabet, essentially the building blocks of all the sounds in our language.

 

Interpretive Reading

 

In Montessori environments, unlike many traditional settings, reading is introduced after writing because the process of reading is cognitively more difficult. Writing is essentially an expression of thought. When we write something, we know what we are writing. When we read something, we don’t know what the author was communicating so we have to take the symbols, match sounds to them, blend them together, and then attach meaning to them. This is much harder to do.

 

While the hand needs to be prepared for writing, the eye must be prepared for reading. This includes being able to follow a left to right, top to bottom progression across the page. In addition, the eye must recognize that the symbols in our language are lines creating a shape. So we have lots of activities with the geometry cabinet, as well as other sensorial materials, to prepare children for this visual discrimination. We also use the sandpaper letters to introduce the phonemes of language through three senses: tactile, visual, and auditory. Through games with the sandpaper letters, children get to practice the trace of the letter through gross motor movement of the whole arm and hand, see the shape, and associate the letter sound with its shape and their own movement.

 

Once children progress from reading words (mostly nouns), to reading phrases and finally sentences and paragraphs, we offer activities to highlight how different words have different functions. These exercises also highlight the syntax or order of words (e.g. adjectives tend to come before the noun they are describing). Another set of exercises, called reading analysis, highlights the role or the order of parts of a sentence. In the process of understanding the components of our language, children are better able to interpret what the author is writing.

 

The Pattern of Human Language Development

 

The progression that young children go through – spoken language to written expression to interpretive reading – follows the pattern of early human language development. Early humans began with spoken language, then advanced into forms of writing (think of the first cave paintings and picture writing), and later moved into reading as a way to interpret the thoughts of others. How amazing that our young children do the same in a matter of years from birth to age six!

 

One of the joys of the Montessori learning environment is how language learning is woven into all aspects of the children’s experience. When we present dusting, for example, we model a left to right, top to bottom pattern, which prepares the eye for tracking words on a page. When children use sensorial touch tablets and the rough and smooth boards, they develop lightness of touch and a relaxed hand necessary for writing. Every time children grasp a knob of the knobbed cylinders, they prepare their hand for holding a writing instrument.

 

Through the sound game, children become aware of the fact that words are made of sounds and they begin to identify all of the sounds in a word and place them in order. Through the sandpaper letters and sandpaper phonograms, children associate the sounds of our language with their symbols. This is exciting work for the children because not only can they see the isolated symbols, but they can touch them, too! Through the moveable alphabet, children are able to write their thoughts even before their hand is ready to control a pencil.

 

The genius of the Montessori approach is that it breaks down individual skills and abilities so that children can practice them in isolation. So by the time children have mastered these individual skills, they seem to spontaneously know how to write or know how to read.

 

Once this explosion into writing and reading has occurred, then children are excited to refine their writing and access worlds of knowledge through reading. A new journey of discovery and learning begins.

 

We invite you to visit the school to learn more about the “explosion” in language development and the joyous journey that unfolds!

If you've spent any time in a Montessori early childhood classroom, you've likely noticed the sandpaper letters on the shelf: elegant, tactile, traced by small fingers again and again. And if you've looked closely, you may have noticed something that surprises many families. Those letters are in cursive. In a world where most children learn to print first, Montessori's cursive-first approach raises questions. Why cursive? Why so early? The answers reach back to Dr. Maria Montessori's own careful observations of children, as well as forward to what modern neuroscience is now confirming about the developing brain. What Dr. Montessori Actually Observed Dr. Montessori was a meticulous observer of children, and her thinking about writing developed through years of direct experimentation. One of her core observations was that children naturally gravitate toward curved, flowing lines rather than the rigid, straight strokes that were (and often still are) the starting point for teaching print. She noticed this pattern across multiple contexts. When children who were learning to write began with rows of straight strokes, their attention would gradually drift, and the straight lines would slowly transform into curves, as if the child's hand were following its own natural inclination. And when children drew spontaneously by tracing figures in sand with a fallen twig, or scribbling freely on paper, they rarely produced short, straight lines. Instead, they made long, flowing, interlaced curves. Dr. Montessori paid attention. Rather than something random, she recognized the hand's natural motion expressing itself. Critical of standard teaching approaches that began with isolated geometric strokes, or regimented mark-making, Dr. Montessori saw that cursive script, with its connected, flowing letters, aligned far more naturally with the motions children were already making. It worked with the child's hand, rather than against it. The Neurological Case for Cursive Thanks to her keen observations, Dr. Montessori intuited benefits that research is now beginning to confirm. Modern brain science provides a compelling case for the value of cursive writing. This is especially powerful in early childhood, when the brain is forming the connections that will support reading, fine motor coordination, and cognitive development for years to come. Dr. William R. Klemm, writing in Psychology Today, summarized findings showing that learning cursive trains the brain to develop what researchers call “functional specialization,” or the capacity for optimal efficiency. Brain imaging studies show how multiple areas of the brain are activated simultaneously during cursive writing in a way that doesn't happen with typing or print. The integration of sensation, movement control, and thinking that cursive requires appears to support broader cognitive development in genuinely significant ways. Klemm also suggested that learning cursive trains the brain for more effective visual scanning, with potential benefits for reading speed and hand-eye coordination. In other words, the child who traces cursive sandpaper letters with their fingertips is developing neural pathways that support a wide range of future learning. Clarity, Beauty, and the Practical Benefits Beyond the neurological research, there are practical reasons that Montessori educators have observed over generations of practice. Cursive provides a better visual distinction between letters that are easily confused in print. Think about the pairs that trip up so many young learners: b and d, p and q. In cursive, these letters look different from one another, which reduces the visual confusion that causes so many children to struggle in the early stages of reading and writing. And then there is the matter of beauty, something Dr. Montessori took seriously in everything she prepared for children. She wrote that, in teaching writing, we should pay close attention to "the beauty of form" and "the flowing quality of the letters." Cursive handwriting, when developed well, is genuinely lovely. It is a form of penmanship that connects children to a long tradition of human expression through the written word. The Montessori approach treats handwriting as a craft worth caring about. What This Looks Like in the Classroom In a Montessori early childhood environment, the path to writing begins long before a child picks up a pencil. Practical life activities like pouring, spooning, buttoning, and lacing quietly help children develop the fine motor control and hand-eye coordination that writing requires. The sensorial materials train children’s pincer grip and refine the precision of small muscle movements. And the metal insets give children practice with the flowing, curved lines that build cursive letters. Then children begin using the sandpaper letters. While verbalizing the phonetic sound, children trace the letter with two fingers. Children feel the letter, produce its sound, and see its form. This multi-sensory experience engages multiple brain areas simultaneously and creates rich, layered associations that support both writing and reading development. By the time children are ready to write independently, they have been preparing their hand and mind for months, often without even realizing it. A Method Ahead of Its Time Dr. Montessori consistently arrived at insights that research has later confirmed. Her reasons for emphasizing cursive were rooted in direct observation of children. She watched children’s hands and their natural movements. She also looked to see what helped them and what created unnecessary struggle. Dr. Montessori wasn't following a trend or a theory. She was following the child. Decades later, brain imaging technology and developmental research are catching up to what Dr. Montessori saw. Flowing lines of cursive script, the sandpaper letters on the shelf, the careful preparation of the hand before children ever pick up the pencil. This is a deep and practical understanding of how children's minds and bodies actually work. For families curious about why Montessori makes this choice, the short answer is this: because children's hands already know how to make these movements. Montessori simply listens to what the hand is already telling us and builds from there. Visit our school in Lenox, MA and see the sandpaper letters and writing materials in action.
