The Power of Color

May 13, 2024

When you look inside a Montessori classroom, you’ll notice the general attractiveness and warm quality of the room. As you peruse the environment, you may also notice the array of colorful materials on the shelves and how they stand out in contrast to some of the neutral feel of the rest of the room.

These colorful learning materials are designed for beauty so that our young children will be drawn to them. However, this isn’t the only reason Montessori materials have distinct colors. The color-coding also helps with organization and structure in the learning environment, and perhaps even more importantly, plays an important role in facilitating children’s cognitive development and learning.

Creating External and Internal Order

In our toddler and primary classrooms, practical life—activities like scrubbing a table, cleaning a window, watering a plant, or creating a flower arrangement—are set up so that all of the objects for a particular activity are arranged by color. This way young children can rely on color cues to know what objects go together and to independently access supplies, like getting a dry apron.

Sensorial materials often use color to help isolate a quality and help children develop their perception. For example, when discriminating dimensions with the pink tower, all of the cubes are the same shade of pink. Color-coding is also used to help children pair two identical sets of materials, like when matching sounds with the sound cylinders.

These forms of color-coding help children with both the order in their surroundings and also in constructing an internal sense of order.

Integrated Throughout

The color-coding gets even more interesting as children move into more academic subjects, like language, mathematics, and even geography.

When our primary children begin to use puzzle maps, they start with the continent map, a two-dimensional representation of Earth, and the continent globe, which shows the planet as a sphere. The puzzle map and the globe show the continents, and each is painted a distant color: North America is orange, South America is pink, Europe is red, Asia is yellow, Africa is green, Oceania is brown, and Antarctica is white. As children begin to learn the physical representation of each continent, they also associate a color with that continent. All other learning materials that involve the continents–such as picture packets, information cards, or booklets–maintain this color scheme.

In the math materials, children learn to associate a quantity with both the number of beads represented and the color of those beads. The beads are the same size but change only by the number on the bead bar and the color. So a ten bar is always constructed of ten gold beads, a nine bar with nine dark blue beads, eight with brown, seven with white, six with light purple, five with light blue, four with yellow, three with pink, two with green, and one with red. This color scheme is consistent throughout all the math materials that use the bead bars, from the simplest lessons in the primary to advanced cubing and cube roots in the elementary and beyond.

Similarly, there is clear and consistent color coding in other materials and concepts, such as with the hierarchy of numbers to designate place value or the role of different parts of speech with the grammar materials.

Strengthening Neural Pathways

While this color coding does continue to help with organization and structure, now the color also helps children with their cognition and memory. Color has long been used as an effective tool in marketing, through brand recognition, consumer attitude, and purchasing decisions.

How the brain processes color impacts our children’s attention, comprehension, and retention. Dr. Maria Montessori may not have had all the current-day studies at her disposal, but she did recognize the power of color in the learning process.

We now know that color connects neural pathways and integrates different forms of intelligence, which allows learners to construct more consolidated meaning and make deeper cognitive connections with content.

When learning the quantity of six, children count the six light purple beads on the bar to determine the quantity of six. At the same time, neurologically they are creating pathways in their brain for quick and easy recall when they see the light purple bead bar so they can immediately think “six” in the future rather than having to count the beads.

Later, when children start to use the bead bars for advanced work with compound multiplication, the distributive law, squaring, cubing, and so much more, the neural connections they have are strengthened by both a clear and concrete understanding of the quantity and the associated color.

Leading to Abstraction

The color-coding in math, language, and other subjects, also helps children move from the very concrete to more abstraction and symbolic representation.

Because they learn to associate nouns with black equilateral triangles and verbs with red circles, as children analyze sentence structure they can begin to parse out the subject and predicate by using those two color-coded shapes and eventually even just the color.

With the understanding that our decimal system place values have associated colors–units are in green, tens are blue, hundreds are red–children can better conceptualize the pattern in the numerical hierarchies because unit thousands are also green, ten thousands are blue, hundred thousands are red, and then unit millions are green, and so on.

This color-coding also helps when we move into operations with larger numbers and quantities. When children move from very tangible representations of a bar of ten beads to represent ten and a square of one hundred beads to represent a hundred, they use small color-coded tiles with just the color and number. Thus children can manipulate a blue tile with 10 printed on it and a red tile with 100 printed on it, and (thanks to the neural pathways established) fully understand what those tiles represent as they add, subtract, multiply, and divide.

A Powerful Aid

The power of color is fully integrated throughout Montessori classrooms and provides an amazing aid to children’s cognitive development. In addition to helping memory and learning, the color brings beauty and appeal to our learning environments while also supporting children’s independence!

Unifying Words and Their Meanings: The Quiet Genius of Montessori Vocabulary Lessons

By Danielle Giordano • April 6, 2026

Have you ever watched a Montessori teacher give a lesson and thought, "That seemed...very short!”? If so, you may have witnessed a three-period lesson. What looks almost effortlessly simple is actually one of the most carefully designed teaching techniques. The three-period lesson is the primary way we introduce new vocabulary to young children. We use it constantly for phonetic sounds, geometric shapes, textures, quantities, names of parts of a flower, names of continents, and so much more. Virtually every time children learn a precise new word for something they're experiencing with their senses, we are using a version of this lesson. Why Vocabulary Needs Its Own Method Young children are in what Dr. Montessori called a sensitive period for language. This is a window of time when children’s minds are especially primed to absorb new words and refine their understanding of them. It’s important to keep in mind, though, that absorbing a word isn't the same as truly knowing it. Children might hear the word "rough" many times without ever firmly connecting that sound to what their fingers actually feel on a piece of sandpaper. The three-period lesson closes the understanding gap. It's built on an insight Dr. Maria Montessori borrowed from educator Édouard Séguin. Learning a word happens in stages: first association, then recognition, then recall. Moving through those stages deliberately, with no extra words or distractions to clutter the lesson, gives children's minds the clearest possible path to making a lasting connection. “Both object and name should strike the child's understanding at the same time — but only the name itself, and not some other word, should be pronounced.” — Dr. Maria Montessori, The Discovery of the Child The Simplicity of the Three Stages Here's how the three-period lesson unfolds. We’ll use a classic example of teaching the words "rough" and "smooth" with our sensorial textured boards. 1. ASSOCIATION — "This is..." The adult presents the object and names it clearly, with no extra words. The child repeats the word while experiencing the sensation. "This is rough." The child runs their fingers across the surface and repeats: "Rough." 2. RECOGNITION — "Show me..." After a brief pause, the adult asks the child to identify the object by name. The child simply points or touches, and thus no verbal answer is needed. "Which is smooth? Which is rough?" The child points to each in turn. 3. RECALL — "What is this?" The adult points to an object, and the child produces the name themselves, demonstrating that the word is now truly theirs. "What is this?" The child touches the surface and answers: "Rough." The whole lesson might take only two or three minutes, and this brevity is part of what makes it work. A child's attention is fully focused on precise vocabulary acquisition. What Happens When a Child Gets It Wrong One of the most quietly radical aspects of the three-period lesson is what happens when a child gets it wrong. If a child points to the wrong texture in the second stage, the adult doesn't correct. We don’t say, "no, try again.” Instead, we just end the activity gently, with the understanding that we will try the lesson again another day. Dr. Montessori was clear about this approach. A correction at that moment doesn't help a child learn the word. In fact, a correction only reinforces the feeling of having failed. So we simply close the lesson. The child carries no impression of having gotten something wrong, and when we revisit the lesson, the child comes to it fresh. As Dr. Montessori wrote, an error in the second period is simply a sign that the child "was not at that instant ready for the psychic association.” Nothing is wrong with the child. The teaching hasn’t failed. It just wasn’t the right moment. After the Lesson: When Words Come Alive One of the loveliest things to observe after a successful three-period lesson is what children do next. A child who has just learned the words "rough" and "smooth" will often wander the classroom touching things: the edge of a wooden shelf, a piece of fabric, the surface of a stone, and quietly naming the texture to themselves. The words become tools for understanding the world, and they want to use them everywhere. This spontaneous generalization is exactly what the lesson is designed to spark. The goal is never for children to recite vocabulary on command. Rather, we want to give them language that deepens and sharpens their experience of everything around them. Trying It at Home You don't need Montessori materials to use this approach. Any time you want to help a young child connect a precise word to something they're experiencing (the names of spices by smell, the names of fabrics by touch, the names of tools in the garden), the same three-step structure applies. Name it clearly. Ask them to show you. Ask them to tell you. Keep it brief, keep it joyful, and if they get stuck, simply set it aside and try again tomorrow. The lesson works because it respects how young minds learn. New connections need space, simplicity, and the freedom to form without pressure.

Our Montessori Bookshelf: Water Connects Us

By Danielle Giordano • March 30, 2026

Rivers are so important to our human story. They are sources of nourishment, transportation, and connection. We see how children are naturally drawn to water, and rivers offer a powerful way to understand ecology, interdependence, and our place within the natural world. With this in mind, we want to share some of our favorite books about water, rivers, and watersheds. Through story and illustration, children can trace the journey of a single drop of water, observe how land and water shape one another, and begin to understand how human choices affect the health of our planet. We’ve grouped the following collection of river and water-focused books by developmental stage. Each title offers language, beauty, and meaningful context for deeper exploration. Whether you are reading with a toddler, a younger elementary child, or an emerging researcher, these books invite wonder, responsibility, and reverence for one of Earth’s most essential elements. For the Youngest Hey, Water! By Antoinette Portis This picture book takes us on a journey of how water is part of our lives in so many ways: from sprinkler spray to a teardrop trickling. The clean-lined illustrations transition between bird’s-eye views and close-up images. This is a great transition book for toddlers moving from pages with one word labeling a picture to a narrative that connects to daily experience. A Place for Rain By Michelle Schaub, Illustrated by Blanca Gómez A lovely introduction to the concept of rain gardens, this picture book follows a simple story of children witnessing how rain runoff can be transformed from being problematic into something stunning and special for everyone. The sweet, slightly geometric illustrations highlight how even simple actions can have a big impact. Water Is Water By Miranda Paul, Illustrated by Jason Chin Although a picture book about the changing states of water, the lyrical text and charming illustrations make this a delightful and fun-filled page-turner! It’s a great way to introduce young children to the water cycle and the importance of water in our lives. Water Cycle: For Younger Elementary Drop: An Adventure through the Water Cycle By Emily Kate Moon Bridging between comic style and traditional picture book, the story follows the character, Drop, as she travels through the water cycle. Delightful and engaging, this is a great book for younger elementary children and can serve as an easy-to-access resource for understanding the states of water. A Drop Around the World By Barbara Shaw McKinney, Illustrated by Michael S. Maydak Written in rhyming verse, this story follows Drop from a cloud near Maine around the world and back to Cape Cod Bay. A map inside the cover shows the journey, and emoji-style images accompany the text, linking to more detailed descriptions of the amazing science at each step along Drop’s path. Watersheds If the Rivers Run Free By Andrea Debunk, Illustrated by Nicole Wong This captivating picture book takes readers through the human story of rivers’ importance in our lives, the mistakes we’ve made, and how we can make things right and help rivers run free again. The rhythm of the text is accentuated by moments of human realization, with bold statements that step out of the rhyming pattern and gently jar us into a sense of action. The illustrations take readers on a journey, too!

How Montessori Makes Long Division Make Sense

By Danielle Giordano • March 23, 2026

For many of us, we remember learning long division as a confusing sequence of steps to memorize and repeat (bring down, divide, multiply, subtract), often without a real sense of why it works. In Montessori classrooms, long division unfolds very differently. Through the Racks and Tubes material, children get to experience what division actually is. Two Ways to Divide: Sharing and Grouping Before introducing the material, we first clarify an important idea: there are two different kinds of division problems in real life. One asks, “If I share this equally, how much does each person get?” This is partitive division, or division by sharing. The other asks, “If I make groups of a certain size, how many groups can I make?” This is measurement division, or division by grouping. The Racks and Tubes material focuses on partitive division. Children physically share quantities equally and discover what one share receives. Materials like the Stamp Game emphasize division of measurement. Together, these approaches give children a complete understanding of division and help them choose the strategy that best fits a given problem. What Are Racks and Tubes? At first glance, the material is impressive and a little mysterious. Children are often drawn to the material, both for its beauty and its seeming complexity. Racks hold test tubes filled with beads, carefully color-coded by place value: units, tens, hundreds, thousands, all the way up to millions. Matching cups hold the dividend (the number being divided). Boards and skittles represent the divisor (the number doing the dividing). Every detail of the material reinforces place value. Each time children need to make an exchange, they trade in one bead of one category for ten of the next category (e.g. one hundred becomes ten 10’s). This process is visible and incredibly concrete. This material takes intentional focus. It takes time. And it makes the steps of long division clear. How Long Division Becomes Concrete When children solve a division problem with Racks and Tubes, they follow a logical, embodied process: They build the dividend using the racks and cups. They represent the divisor with individual figures on boards. They share beads one at a time, equally, to each part of the divisor. They stop when sharing is no longer possible and then see what remains from that category. They then bring down the next category of beads to continue the sharing process. Each step answers a real question: What does one unit get? What happens when we run out? What do we do with what’s left? Instead of being told “bring down the next digit,” children literally bring down the next category of beads. When exchanges are needed, they perform them physically by trading beads. Remainders are not mysterious leftovers. They are beads still sitting in the cup. Long division becomes a story children can follow. From Material to Abstraction One of the most beautiful aspects of this work is how naturally it leads into abstraction. At first, children record only the quotient. Later, they begin recording intermediate remainders. Eventually, they discover that multiplying the quotient by the divisor tells them how much has been used at each step. This is the very heart of the traditional algorithm. We don’t give abstract shortcuts. Instead we help children discover the pattern. This allows them to own the process. By the time children are working abstractly on paper, the algorithm already makes sense. It matches what their hands have done again and again. Why This Matters The Racks and Tubes material does more than teach division. It teaches: Deep place value understanding Logical sequencing Patience and precision Trust in one’s own reasoning Most importantly, it gives children confidence. Division is no longer something done to them. Instead, they can think through the process, step by step, with meaning and understanding. In Montessori, math is not about getting the answer quickly. It’s about building an understanding of why the process and answer makes sense. And with Racks and Tubes, long division finally does!
