Materials Spotlight: The Color Tablets

Montessori School of Louisville • October 23, 2023

Young children are constantly absorbing information about the world around them! Some of it is very concrete, while some is abstract. 


Color as an Abstraction


Think about the color red. Red as a quality does not exist in nature. Red can be represented in physical things, but you can’t bring “red” to another person. We can find a red apple, a red street sign, a red flower, but we can’t find just red. Red is an abstraction.


In Montessori environments, we are mindful of how we introduce young children to these kinds of abstractions. We try to represent the intangible quality in a physical form and to isolate it so that children can really focus on the quality and the language connected to that attribute. Every variable is held constant except for the one characteristic to experience and explore. We do this to give children the clearest, most precise images we can. 


These materials that we use to introduce the abstract concept of color are called the color tablets because each color is represented on a tablet. The tablet with red looks exactly like every other tablet in our color box, except for its color. Each tablet has the same size, weight, and shape. The only variation is the color. This materialized abstraction allows us to put “red” in the child’s hands to experience and explore. The Montessori color tablets are organized into three boxes.


First Color Tablet Box


The first color tablet box is composed of three pairs of color tablets: red, blue, and yellow. These primary colors represent the extremes of color. With this first box we awaken children’s sensory awareness by introducing how to pair the matching color tablets. There are two of each variable and children find the mates. Cognitively it is easier for children to notice sameness than difference.


In this first stage, we also demonstrate how to handle the material and how to experience the sense. If a child can’t distinguish the extremes of the set, we get important information about their sensorial perception. Sometimes the child isn’t successful at this first stage because they aren’t yet comprehending the concept of sameness. Thus we must be very careful to let children know how we are pairing the items by finding the matching the tablet that looks exactly like the one we have selected first. This isn’t just random pairing, but rather is based upon a specific perception. Often children don’t spend too long with this first box of color tablets, although some young children will be drawn to the simple beauty of the three primary colors. 


Second Color Tablet Box


With color box two, the focus is still on finding similarities, however, there are more variables. For example, color box two has primary colors and secondary colors, as well as brown, grey, black, and white. This adds more variables for children to search through to find the match and thus requires them to use a finer level of discrimination. When we add more variables, the differences between them become smaller and not as extreme. This challenges children’s exactness and precision.


Third Color Tablet Box


The third box of color tablets is divided into seven or eight compartments each with a gradation of one color from dark to light. Children begin using this box when they have been successful pairing with more variables because grading by shade requires a higher level of discriminating difference. Children’s attention has to be focused on a slight unit of difference. Is the blue just lighter than the last shade of blue? This is cognitively much harder!


Just these three steps are not enough to ensure the maximum amount of depth of experience with the materials. Thus, we extend work with the color boxes by offering language and memory games.


Language Extensions


After children have some experience with the material and we observe that they are successful in consistently pairing two colors together, we offer children language to accompany the abstraction. Language fixes the sensorial quality in their minds and aids memory and recall. We don’t want to give language to images that are not clear, because that confuses children. When children are successful pairing colors, we offer the names of the colors. Then when children are successful in grading the shades of a color, we offer the comparative terms (darker than, lighter than) and superlative expressions (darkest red, lightest red). 


Memory Games


Memory games help children discover sensorial qualities in the world around them. In the first memory game, children put one set of the paired color tablets in one location and the second set in random order somewhere else in the room. The trick is to have the second location be just far enough away so as to allow enough time for children to retain a memory of the color. To play the game, children place a “memory marker” next to one of the color tablets lined up in the first location. They then hold that color, such as “red”, in mind and walk to the second location. There they find the red tablet and bring it back to place it by its mate. Children then move the memory marker to another color tablet and continue. 


When children are successful with this, they can try a harder variation of this game in which they use a tray to place the second set of color tablets in scattered locations around the room. When children go to find the matching color tablet, they must retain the impression in their memory for a longer time and not be distracted by the other things they see as they walk around the room. 


Children can also play a game of matching each color tablet to a material in the classroom. For this game, children use the memory marker to indicate which color tablet they are using. They then study the color tablet, leave it on the rug or table, and then search the environment for an object that has the same exact shade of the color. When they find the object, they bring it back and place it next to the selected color tablet.


Keys to the World



If we think about the world of color, we realize there are an infinite number of colors, shades, etc. We don’t give children every color of the world. We give the keys: the primary colors, then the secondary colors, then black and white, and a few other colors. Every other color is made from those keys!


The color tablets are one of the more lovely and inviting materials we use in the Early Childhood classrooms. Come visit our school and see how young children internalize these kinds of abstract concepts and, in the process, develop a refined sensorial ability!

When Dr. Maria Montessori began developing her curriculum for elementary-aged children, she recognized that their educational needs undergo a profound transformation. Academic skills become more complex, but more importantly, the way content is delivered must fundamentally shift. In the elementary years (ages 6–12), children transition away from the sensory, hands-on physical boundaries of early childhood and move toward an expanding intellectual horizon. Around age six, a child’s scope of vision expands exponentially beyond themselves. Social connections become paramount, a vivid imagination awakens, and a deep curiosity takes hold regarding the universe, society, and their own place within the big picture. To meet this developmental leap, Dr. Montessori created Cosmic Education—a holistic framework that presents the story of the universe and humanity’s interconnected role within it. The Five Great Lessons: Springboards for Imagination At the heart of Cosmic Education are the Five Great Lessons. These are not intended to be exhaustive academic lectures; rather, they are dramatic, impressionistic stories designed to ignite the child's imagination and serve as a springboard for all future research and learning. Because children spend three years in each elementary community (Lower Elementary: ages 6–9; Upper Elementary: ages 9–12), they experience these lessons three distinct times. Each year, as their cognitive capacity grows, the lessons reveal deeper layers of meaning, sparking fresh, student-led exploration in chemistry, history, mathematics, language, and the sciences. Great Lesson 1: The Creation of the Universe Typically presented at the start of the school year, this lesson offers a captivating sense of wonder. Guides intentionally prepare the atmosphere: drawing the blinds, dimming the lights, and gathering children around a series of impressionistic materials and science experiments. The story begins in the vast, cold darkness before the universe existed, building up to the instantaneous moment of creation. Through striking demonstrations, children observe: How particles moved together and apart The speed of light and the immense scale of stars States of matter (solids, liquids, gases) The formation of the solar system, the cooling of the Earth, and volcanic activity Follow-Up Studies: This lesson serves as the gateway to physics, chemistry, astronomy, geology, physical geography, and the scientific method. Great Lesson 2: The Coming of Life As the school year progresses, attention shifts to how life emerged on Earth. To help elementary students grasp deep time, guides utilize impressionistic visual materials: The Long Black Strip: A long runner of black fabric representing Earth's vast lifespan, ending with a tiny sliver of white to represent all of human history. This material provides a humbling visual perspective on our planet's timeline. The Clock of Eras & The Timeline of Life: Colorfully illustrated charts detailing life’s evolution from single-celled organisms through early plants, invertebrates, vertebrates, and dinosaurs. Follow-Up Studies: Children dive into biology, Botany, Zoology, the five kingdoms of life, vertebrate classification, and paleontology through fossil studies. Great Lesson 3: The Coming of Humans This lesson introduces early human ancestors and the arrival of human consciousness. Children reflect on what makes human beings unique—our ability to think, reason, feel deeply, and collaborate to invent tools that solve complex problems. Guides introduce the Fundamental Needs of Humans, demonstrating how all people throughout history and across cultures share the exact same core requirements for survival and fulfillment (shelter, nourishment, clothing, defense, spiritual expression, and art). Follow-Up Studies: Ancient history, cultural anthropology, world geography, social studies, and human migration patterns. Great Lesson 4: The History of Mathematics Elementary students are fascinated to discover that mathematics was not created out of thin air, but was invented by ancient civilizations to solve real-world problems, like measuring land, trading goods, and tracking time. By learning about the contributions of the Babylonians, Egyptians, Greeks, Mayans, and early Indian mathematicians who developed the concept of zero, children realize that numbers are a shared human heritage. Follow-Up Studies: When children work through subtraction, long division, or geometry, they ground their practice in historical context, making abstract math deeply meaningful and engaging. Great Lesson 5: The History of Language Similar to the history of math, this lesson illuminates how written language evolved. From early cave paintings and Egyptian hieroglyphics to the Phoenician alphabet and the printing press, students learn how humans captured spoken thoughts to communicate across distance and time. Follow-Up Studies: Because elementary students are actively refining their reading, grammar, creative writing, and research skills, understanding the origin of words (etymology) inspires pride and curiosity in their literacy work. Experiencing Cosmic Education at MSL Cosmic Education gives children a sense of purpose and belonging. Instead of delivering isolated facts, Montessori presents the whole universe first, allowing students to see how every detailed subject connects back to the grand story of life.
