Montessori’s 4 Planes of Development Every Parent Must Know

The concept—4 planes of development—was first introduced by Dr. Maria Tecla Artemisia Montessori, an Italian physician and educator.

Grounded in the Montessori philosophy, Maria Montessori, a name she later became synonymous with, used the concept to highlight the theory that human development unfolds in distinct and consecutive stages. Each of these stages has its unique characteristics and sensitivities, and they help understand the different approaches to learning and growth that parents must have towards a child’s development.

Understanding the 4 planes of development is necessary for creating an enriching and prepared environment for a child so that it is carefully built to meet your child’s specific needs and interests at each stage. Montessori encourages parents to understand their child’s natural curiosity, need for independence, and self-discipline, so that they can grow at their unique pace and in their preferred learning style.

Stages of development: The 4 planes of development

The four planes of development Montessori describes the distinct stages of a child’s growth. Each of these stages helps provide a deep insight into the child’s specific needs and learning nature.

The basic framework can be divided into the following 4 planes:

• The First Plane: Ages 0 – 6 years (Early Childhood)
• The Second Plane: Ages 6 – 12 years (Childhood)
• The Third Plane: Ages 12 – 18 years (Adolescence)
• The Fourth Plane: Ages 18 – 24 years (Maturity)

The Montessori philosophy views education as a journey that should extend beyond the traditional boundaries of academic achievement. And this is why Montessori classrooms are designed in a manner that respects your child’s unique pace and provides an environment for their growth that supports nurturing and individual spaces.

As a result, your child will learn to grow into responsible, compassionate, and globally minded individuals who feel motivated enough to make a difference in the world.

Decoding the 4 planes of development – the phases of life

Your child will undergo several distinct phases of growth as they journey through their formative years. They will transition from the cute infancy period to excited toddlerhood, and this will be marked by rapid physical development and bonding with caregivers. This phase will also be when they will be curious to explore their environment.

The years of early childhood mark the time when their imagination flourishes, giving rise to playful creativity and a thirst for learning. It introduces them to the joys of education, fostering cognitive, social, and emotional growth.

Each of the 4 planes of development is marked by distinctive traits and psychology, and understanding these can help parents create the right environment as their children grow older.

And just like that, soon enough, they are ready to acquire new skills and assert their newfound independence as they step into adolescence. Numerous physical and emotional changes also occur during this phase, and they need to navigate these changes and reach the path towards self-identity and autonomy.

By the time they move onto adulthood, they are ready to explore the upcoming transformations of life. Life now will involve making crucial life decisions, like educational, career choices, and in relationships. There is excitement for the new, but there is also uncertainty as they navigate the complexities of 4 planes of development.

With time, they gain a greater sense of stability and self-assurance. Interestingly, the experiences and lessons learned during childhood are an important foundation for the values, strengths, and aspirations of adulthood.

First Plane: The early childhood phase of the 4 planes of development

Ages 0 – 6 years (Early Childhood)

During this phase, your child will focus on absorbing everything they come in contact with. They are sensitive to their surroundings and the people who are interacting with them. Referred to as the period of the “absorbent mind,” this stage is characterised by children effortlessly soaking up information from their environment.

The Montessori first plane of development is characterised by rapid physical and cognitive development. During this period, fundamental skills like motor skills and language develop. Your child becomes aware of their senses and begins to explore their surroundings through their senses slowly. There is also an effort towards socialisation during this stage of the 4 planes of development.

As parents, you too must focus on developing their habits through hands-on experiences, inclining more toward the usage of the senses to understand concepts and refine their movements. It must also be noted that the foundation for the child’s personality is also set at this stage.

Second Plane: The childhood phase of the 4 planes of development

Ages 6 – 12 years (Childhood)

During this time, your child will undergo significant physical and psychological changes. The second plane of development, Montessori-focused growth, is typically characterised by a strong desire to explore everything independently. This craving for independence is both mental and physical.

They will experience “intellectual explosion,” where their reasoning and abstract thinking abilities will develop rapidly. Children at this stage become increasingly independent in their thoughts and actions, and they are eager to investigate and question everything around them. They now start developing a more conscious and deliberate approach to learning.

Senses towards morality and justice also evolve as they develop a deeper conscience. Deep friendships also begin to form during this stage of the 4 planes of development.

Third Plane: The adolescent phase of the 4 planes of development

Ages 12 – 18 years (Adolescence)

During this period, there is an increased tendency for teenagers to question authority and societal norms as they strive to find their place in the world.

In the third plane of development, Montessori, it must be noted that your little child is now a young person who has entered a stage where they have developed a strong desire for social engagement. They will now show increased interest in societal issues and the broader world. They begin to focus on their place in society and explore their potential roles as contributing members of their community.

The evolution of their personality reaches a heightened level during this stage. They crave a sense of belonging in different groups, trying to fit in, and in this process, they require proper nutrition and rest to grow appropriately. The adolescent phase of this 4 planes of development phase focuses on social personality and orientation.

Fourth Plane: The maturity phase of the 4 planes of development

Ages 18 – 24 years (Maturity)

This is like the culmination point of all four planes of development, when your child will start to seek stability and responsibility in life. Young adults in the fourth plane of development Montessori, are refining their life skills and making important decisions that will shape their future.

Personal choices and decisions become more intensified during this period, and sensitivity towards personal responsibilities also heightens. The spiritual self is also a focus during this stage of growth.

Applying the 4 planes of development to your child

Before venturing into developing the educational approach for your child, it is necessary to note that the ages specified for each plane are approximate, and individual variations can occur.

Therefore, it is required to respect your child’s pace of growth and tailor the needs of each child based on it.

By understanding the four planes of development, parents, educators, and caregivers can better support children and young adults in their journey of self-discovery, learning, and personal growth.

And in order to establish the Montessori philosophy, it is essential to focus on their holistic development. Your child is naturally empowered to flourish into a well-rounded and confident individual, so all you need to do is create a stimulating environment for them to thrive in. This environment will prepare them and encourage exploration and independence.
