Stages of Development Series: Childhood
March 10, 2025

Understanding human development at each stage is crucial to fostering optimal growth. This belief forms the foundation of Montessori education, which is deeply rooted in the developmental needs of children. 


This post is the second in a series that explores the four stages of human development: birth through age six, ages six to twelve, ages twelve to eighteen, and ages eighteen to twenty-four. Each of these stages, or planes of development, comes with unique needs and capacities, and understanding them allows us to better support children in their educational journey.


Childhood (Age Six to Twelve)


Unlike the dramatic changes seen in infancy and adolescence, the second plane of development (ages six to twelve) is often viewed as a period of relative stability. This phase serves as a critical time for children to build upon their early experiences while preparing for the transitions that will come in adolescence. Despite its importance, this period is sometimes overlooked in society, but it is essential for the development of social, intellectual, and emotional skills that will serve as a foundation for later life.


Key Characteristics of Elementary Children


At the core of this stage are several observable characteristics.


Physical Sturdiness and Stability

Children in this stage experience a steady period of physical growth. They lose their primary teeth and gain adult teeth. Their skin loses its baby softness. Their hair even gets coarser and darker. Their body becomes leaner and stronger, with the soft, rounded contours of early childhood giving way to a more defined physical form. Despite these changes, growth slows down compared to the rapid pace of the first plane. This time also brings greater stability in health and coordination.


Reasoning and Abstraction

While children in the first plane absorb information effortlessly and even unconsciously, the second plane is marked by a growing capacity for reason and abstraction. No longer content with simply absorbing facts, children seek to understand the underlying causes of things. They begin to ask “why” questions and develop the ability to think logically and critically about the world around them. Their imagination flourishes and they love being able to transcend time and space, mentally traveling through history or exploring possible futures.


Conquest of Independence

This is a time when children transition from sensorimotor learning to becoming intellectual explorers. The intellectual independence they gain during this phase fuels their studies of mathematics, history, geography, art, and music. Montessori classrooms provide opportunities for children to explore these subjects with the motto: “Don’t tell me. I’ll figure it out myself.” Their journey toward independence extends beyond the academic to include a growing capacity for social reasoning and moral judgment.


The Herd Instinct and Socialization

One of the defining features of children in the second plane is their social nature. Children at this age exhibit a strong "herd instinct"—the need to belong to a group and collaborate with peers. They begin forming micro-societies and creating their own rules, roles, and expectations. These experiences allow them to practice social interactions and develop their conscience. It’s worth noting that as adult-directed activities (e.g. afterschool sports and classes) increase, children have fewer opportunities to work out social dynamics independently.


Moral Development and a Sense of Fairness

As elementary-age children seek independence, they also begin to develop a sense of morality. Children at this stage are sensitive to fairness and justice, and are likely to voice concerns when they perceive inconsistencies. This is when we frequently hear, “It’s not fair!” This stage is about the exploration of right and wrong and the ability to question rules and authority. The drama that unfolds in the classroom is often part of this process, as children navigate the complexities of social rules and develop their moral code.


A Fascination with the Extraordinary

Second plane children are drawn to the extraordinary, whether in the form of superheroes, mythical creatures, or fascinating civilizations. Their imagination is sparked by the idea of powers beyond the ordinary, and they are eager to explore cultures and histories that seem larger than life. This fascination with the exceptional provides them an avenue for exploring concepts of heroism, strength, and the human condition.


A Supportive, Community-Based Learning Environment


In a Montessori classroom, children are encouraged to work both independently and in groups. As such, the prepared environment of the second plane is designed to foster collaboration while allowing space for individual exploration. Group activities allow children to develop their social skills, negotiate rules, and practice taking on different roles within a community. Through these experiences, they are able to form their own moral code and develop their identity in relation to the group.


Children in this stage also have a thirst for knowledge that goes beyond what is available in the classroom. Montessori education encourages “Going Out” experiences—trips beyond the school to explore the wider world. These excursions allow children to engage with real-world problems, develop planning and execution skills, and build a deeper understanding of the subjects they are studying. Through these experiences, children come to see themselves as active participants in the world around them.


Montessori referred to the educational experience in the second plane as "cosmic education." In this phase, children are introduced to the universe as a whole, with an emphasis on the interconnectedness of all life. The Montessori curriculum for this stage revolves around the Five Great Lessons, which invite children into discovering more about the universe, the formation of the earth, the coming of plants and animals, the arrival of humans, and the development of written language and numbers. From these lessons, all areas of study—botany, geography, history, zoology, language, and more—emerge, inspiring awe and gratitude for the universe and humankind’s place within it.


Support from Home and Community


While second plane children are eager to explore beyond the family and classroom, they still require the strong support of their home, school, and peer group. Social activities become increasingly important, as group work provides them with the opportunity to practice collaboration, moral judgment, and self-expression. A strong, supportive environment—both at home and at school—helps children navigate this important stage in their development.

Practical Life Has Purpose!
May 19, 2025
The Purposes of Practical Life in Montessori In a Montessori classroom, practical life activities play a foundational role in supporting children’s development, independence, and connection to their environment. Because children are actively absorbing and adapting to the world around them, everything we offer in practical life serves a developmental need. Supporting Independence One of the primary goals of practical life is to nurture children’s functional independence—the ability to care for oneself and the environment and interact meaningfully within a community. The first plane of development (0 to 6 years) is marked by a strong drive for independence, with children eager to do things for themselves. By the time a child enters the Children’s House (approximately ages 2.5 to 6), they have already made strides toward independence. However, they still require an environment that allows them to refine their skills. In the world, children generally encounter a number of obstacles to their independence: Household processes (e.g., cleaning dishes in the dishwasher) may be hidden or too complex. Tools are adult-sized and difficult for small hands to use. Movements happen too quickly for children to absorb (e.g., tying a shoe). The Montessori environment addresses these barriers by providing: Child-sized tools for daily activities, such as preparing food and caring for the classroom. A clear, ordered sequence of movements that children can observe and repeat. The freedom to practice skills at their own pace, allowing them to move from passive observers to active participants. Supporting the Sensitive Period for Movement We also recognize that young children are in a critical period for refining their control and coordination. So practical life activities are designed to help children refine their movements in purposeful ways, directing children’s attention and energy toward focused, intentional actions. Walking on the line of an ellipse develops balance and control. Pouring water from a basin to a bucket refines precision. Carrying a tray teaches careful, measured movements. One of the most challenging yet essential aspects of movement is control. It takes effort to stop pouring just before a cup overflows or use only a small drop of polish when shining an object. By engaging in these exercises, children strengthen their willpower and gradually master their own actions. Supporting the Sensitive Period for Order Children in the first plane of development have an innate need for external order, which is reflected in their surroundings and daily routines. Montessori environments support this in a variety of ways. We ensure that activities have a logical sequence of steps so as children learn new concepts, they can also rely on the sequencing. Materials are placed in a specific order on the shelves, moving left to right and top to bottom so children begin to internalize the same patterning we use for reading as they work through the easier and most concrete activities to the most challenging and abstract. Montessori activities are color-coded. For the youngest children this means that all of the items for something like window washing will have the same color which helps children keep the set together. As children get older the color-coding is designed to help them grasp concepts like place value in math or parts of speech in language. Once children internalize these structures, they gain confidence and independence, allowing them to complete tasks from start to finish without adult intervention. Assisting with Cultural Adaptation Practical life activities reflect real-world tasks that children observe in their daily lives. Children are naturally drawn to meaningful work—they want to help, imitate, and participate. For example, in Dr. Montessori’s early observations in San Lorenzo, she saw that children were fascinated by the gardener and the custodian, eagerly following and watching their work. Children see adults doing marvelous activities, and children want to learn the skills to participate! Through practical life activities, children engage in culturally relevant tasks that allow them to feel like valuable members of their community. Supporting Orientation Orientation is a fundamental human tendency—we all seek to understand our surroundings and how to function within them. Practical life exercises help children orient to the Montessori classroom by introducing essential routines. For example, we take the time to teach children things that might otherwise be taken for granted, such as: How to carry a chair properly. How to greet a friend. How to roll and unroll a work rug. How to ask for help. By taking time to demonstrate these tasks, we show respect for the child and provide the knowledge they need to act confidently in their space. Supporting the Development of Concentration Practical life activities serve as a gateway to deep concentration. The freedom to choose and repeat exercises allows children to follow their intrinsic motivation and work toward self-perfection. When children reach deep concentration, they experience: Joy and a sense of fulfillment. An increased connection to others. A natural reduction in undesirable behaviors. The ability to repeat an activity for as long as needed also supports children’s sensitive period for order and mastery. This is why practical life often serves as the first point of engagement for children in the Montessori classroom. Supporting the Development of the Will Practical life exercises help children develop willpower and self-control by bridging the gap between impulse and deliberate action. At first, children act on instinct, but through repeated exercises, they learn to: Act consciously and voluntarily. Perfect their actions through self-correction. Develop grace, courtesy, and social awareness. Whether through learning how to clean up a spill or preparing snack to share with others, children learn to control their impulses and consider the needs of others. Dr. Montessori beautifully summarized this transformation in The Discovery of the Child: “The grace and dignity of their behavior and the ease of their movements are the corollaries to what they have gained through their own patient and laborious efforts. In a word, they are ‘self-controlled,’ and to the extent that they are thus controlled, they are free from the control of others.” Practical life is far more than just pouring, scrubbing, and folding—it is the foundation for independence, concentration, order, and social development. These carefully designed activities help children orient to their world, refine their movements, and develop the willpower to act with purpose. By embracing practical life, we give children the tools to engage meaningfully with their environment, take ownership of their learning, and ultimately, become confident, self-sufficient individuals.
