Parents and educators often use Montessori and sensory play in the same breath — but they are not the same thing. This guide explains what each approach actually means, where they overlap, where they diverge, and why combining both produces richer outcomes for young children than choosing one over the other.
What is the Montessori approach to early childhood?
The Montessori method was developed by Italian physician and educator Maria Montessori in the early 1900s, initially with children living in poverty in Rome. What she observed, that children have an innate drive to learn, and that they learn best through purposeful, self-directed activity in a carefully prepared environment, became the foundation of one of the most widely implemented educational philosophies in the world.
Montessori is not a set of activities or a collection of specific materials. It is a philosophy of child development grounded in respect for the child's natural learning drive, belief in the child's capacity for self-regulation, and the educator's role as a prepared observer rather than a director of learning.
The core principles behind Montessori education
The absorbent mind. Children under six absorb information from their environment effortlessly and unconsciously not through deliberate instruction, but through living and experiencing. This is why the quality of the environment matters so profoundly in the Montessori approach.
Sensitive periods. Montessori identified windows of heightened receptivity in early childhood, periods during which a child is particularly attuned to acquiring specific skills. Sensitive periods for language, order, movement and sensory refinement all occur in the first six years of life.
The prepared environment. The Montessori environment is not a room full of toys — it is a carefully curated space designed to match the child's current developmental stage, invite independent exploration, and allow the child to choose their own work. Every material has a purpose, a place, and a correct way to be used.
Auto-education. Children teach themselves through interaction with the right materials at the right time. The educator's role is to observe, prepare the environment and introduce materials not to instruct, correct or direct.
What a Montessori environment actually looks like
Materials are accessible and ordered at child height, on low open shelves, arranged to invite independent selection and return. There is no toy box. There is no clutter.
Materials are purposeful and isolated in difficulty. Each Montessori material targets one specific skill or concept a set of graduated cylinders teaches size discrimination, a set of colour tablets teaches colour matching. The material isolates the learning point so the child can focus without competing variables.
Activities are self-correcting. Montessori materials are designed so the child can identify and correct their own errors without adult intervention, building intrinsic motivation and resilience rather than dependence on adult approval.
Montessori in a home or Family Day Care setting
Applying Montessori principles at home does not require specialist furniture or expensive materials. Accessible storage at child height, a limited and rotated selection of purposeful materials, and an adult who observes before intervening are the essentials.
The Montessori Pouring and Transferring Set, Montessori Wooden Sorting Bowls and Montessori Wooden Sorting Trays are designed specifically for this context — purposeful, self-correcting where possible, and suited to independent use by young children in a home or care setting.
What is sensory play?
Sensory play is any activity that deliberately engages one or more of a child's sensory systems. Unlike Montessori, it is not a comprehensive educational philosophy — it is a category of experience that can exist within many different pedagogical frameworks, including Montessori itself.
The purpose of sensory play is to provide rich, varied input to the sensory systems in a way that supports neural development, sensory processing, emotional regulation and cognitive growth. It is grounded in neuroscience and occupational therapy as much as in education which is part of what makes it distinct from Montessori as an approach.
The sensory systems sensory play targets
Most people think of sensory play as primarily tactile — water, sand, kinetic sand. But a complete sensory play program targets all seven sensory systems:
| Sensory system | What it involves | Example activity |
|---|---|---|
| Tactile | Touch, texture, temperature | Sensory bins, water play, finger painting |
| Visual | Light, colour, contrast, pattern | Light panel exploration, colour sorting |
| Auditory | Sound, rhythm, pitch | Percussion instruments, sound matching |
| Olfactory | Smell, scent discrimination | Natural scent exploration |
| Gustatory | Taste, oral sensory input | Mouthing (babies), food play |
| Proprioceptive | Body awareness, deep pressure | Heavy work, pouring, carrying |
| Vestibular | Movement, balance, spatial orientation | Rocking, spinning, climbing |
The Illuminated Exploration Board targets visual processing. The Montessori Wooden Percussion Set targets auditory processing through cause-and-effect sound production. The Silicone Sensory Play Tools Collection targets tactile and proprioceptive input simultaneously.
Sensory play as a standalone approach vs a pedagogical tool
Sensory play can function as a standalone practice offered for its own sake, for regulation, enjoyment and sensory development or as a pedagogical tool embedded within a broader educational approach. In a Montessori environment it might appear as a carefully presented sensory material on the shelf. In an occupational therapy context it might appear as a targeted intervention for a child with sensory processing differences.
This flexibility is one of sensory play's greatest strengths and one of the reasons it is so often conflated with Montessori. Understanding where they differ requires looking at the intention behind the experience, not just the materials being used.
Where Montessori and sensory play overlap
The confusion between Montessori and sensory play is understandable. At the surface level, both prioritise child-led exploration over adult-directed instruction, favour natural and open-ended materials over plastic toys with prescribed uses, and place significant emphasis on the quality and design of the environment as a learning tool in its own right.
In both approaches, the adult's most important work happens before the child arrives at the activity in the thinking, selecting and arranging that shapes what the child encounters. And in both, learning happens through the hands, through touching, manipulating, pouring, sorting and exploring physical materials in the real world.
The Nature Play Essentials Wooden Parts Set and the Montessori Early Learning Set sit comfortably within both frameworks natural materials, open-ended use, and a design that invites exploration without prescribing a single correct outcome.
Where Montessori and sensory play diverge
Understanding where the two approaches differ requires looking beyond the materials to the intention, structure and theoretical foundation of each.
Structure and intentionality
Montessori is a highly structured approach, even though it looks free from the outside. Every material has a specific purpose, a specific place, a specific way to be introduced and a specific skill it is designed to develop. The freedom the child experiences is freedom within a carefully designed structure.
Sensory play is inherently open-ended. There is no correct way to explore a sensory bin. There is no skill hierarchy in a water tray. The invitation is to explore and follow curiosity without a predetermined outcome.
The role of mess and sensory experience in Montessori
Montessori is not anti-mess but it is deliberate about mess. Montessori sensory experiences provide rich tactile input within a controlled, purposeful format. The mess, when it occurs, is a consequence of purposeful activity rather than the point of the activity itself. Sensory play, particularly in its more free-form expressions, often makes mess the medium rather than the side effect, the sensory experience of the mess itself is the primary learning.
Developmental focus - practical life vs sensory processing
Montessori's developmental focus in the early years is primarily on practical life skills, Â pouring, spooning, folding, buttoning, sweeping that develop fine motor control, concentration and independence. Sensory play's developmental focus is explicitly on sensory processing, the nervous system's ability to receive, organise and respond to sensory input. This makes sensory play particularly valuable for children with sensory processing differences or autism spectrum disorder. Montessori addresses these needs indirectly sensory play addresses them directly.
How each approach handles adult involvement
In Montessori, the adult's involvement is largely pre-activity observing the child, preparing the environment, choosing when to introduce a new material. During the child's work, the Montessori adult observes and resists the urge to intervene.
In sensory play, adult involvement during the activity is often more active — narrating the sensory experience, extending through language, introducing new elements mid-session. This reflects sensory play's roots in occupational therapy and attachment theory, where the adult's responsive presence is part of the therapeutic value of the experience.
Can you combine Montessori and sensory play?
Yes — and the most effective early childhood environments do exactly that. Montessori is a philosophy. Sensory play is a category of experience. They operate at different levels, which means they can coexist within the same environment, the same session and even the same activity.
Activities that are genuinely both
Some activities sit so naturally at the intersection of both approaches that distinguishing between them is unnecessary:
Pouring and transferring with natural materials. A core Montessori practical life activity and a rich tactile and proprioceptive sensory experience simultaneously. The Montessori Pouring and Transferring Set is designed for exactly this intersection.
Sorting with natural loose parts. A Montessori sensorial activity and a sensory play experience at once. The Montessori Rainbow Pebbles Learning Set sits at this intersection — purposeful enough for a Montessori shelf, open-ended enough for free sensory exploration.
Musical instrument exploration. The Montessori Wooden Percussion Set invites cause-and-effect discovery and isolated sound discrimination alongside rich auditory sensory input — genuinely both approaches in one activity.
Stacking and nesting. The Silicone Nesting Bears and Montessori Stacking Tree develop seriation and size discrimination while providing rich proprioceptive and tactile sensory input simultaneously.

What early childhood research says about both approaches
The evidence base for Montessori
The research on Montessori education is more robust than for most early childhood approaches. A landmark study published in Science by Lillard and Else-Quest in 2006 compared children in Montessori and conventional preschool settings and found significantly better outcomes in executive function, reading, mathematics and social cognition for Montessori children. More recent research has replicated these findings consistently, citing the Montessori emphasis on intrinsic motivation and self-directed work as the primary mechanism.
The evidence base for sensory play
The evidence base for sensory play draws from neuroscience, occupational therapy and developmental psychology. The foundational research on sensory integration theory, developed by occupational therapist Jean Ayres in the 1970s, established that the brain's ability to receive, organise and interpret sensory input is foundational to all other learning. More recent neuroscience confirms that rich sensory environments in early childhood produce measurable differences in neural connectivity, particularly for children with developmental differences or sensory processing challenges.
Which approach is right for your child?
The honest answer is that this is the wrong question. Neither Montessori nor sensory play is a complete answer on its own and the child in front of you is a more reliable guide than any framework.
Questions to help you decide
Does your child seek or avoid sensory input? A child who actively seeks intense sensory experiences may benefit most from a sensory play program that addresses regulatory needs directly. A child who is more settled and focused may thrive with the structured independence of a Montessori environment.
What is your goal for this activity? If the goal is developing a specific skill, a Montessori-informed approach is likely most effective. If the goal is regulation or sensory exploration, sensory play is the more direct tool.
What does your child tell you through their play? The most reliable guide is careful observation of what they choose, what they return to, what they avoid and what sustains their engagement. Both approaches share a deep commitment to observation as the foundation of responsive practice.
Why the either/or framing misses the point
The educators and parents who produce the richest outcomes for young children are those who draw fluidly from multiple frameworks using Montessori's structure and intentionality where it serves the child, and sensory play's openness and regulatory focus where that serves better.
Cintia Lemm's practice at CC's Family Day Care reflects this integration. After 22 years in early childhood education, her approach is not defined by a single framework — it is defined by careful observation of each child and deliberate selection of materials that meet that child's current needs. Sometimes that looks like Montessori. Sometimes it looks like sensory play. Often it looks like both at the same time. Every product at CC's Sensory Play is stocked because it has demonstrated genuine value in the hands of real children, across a range of approaches and contexts.

FAQ — Montessori vs sensory play
What is the difference between Montessori and sensory play?
Montessori is a comprehensive educational philosophy grounded in child-led learning, prepared environments and purposeful materials. Sensory play is a category of experience, any activity that engages one or more sensory systems, that can exist within Montessori or any other pedagogical framework. Both prioritise hands-on exploration with natural materials, which is why they are so often confused.
Is sensory play part of Montessori?
Partly. Montessori includes specific sensorial materials such as the colour tablets and rough and smooth boards, designed to refine sensory discrimination. However, free-form sensory play such as a kinetic sand bin or a water tray sits outside traditional Montessori practice because it lacks the structured purpose and self-correcting design that Montessori materials require.
Can you do Montessori and sensory play together?
Yes. Activities like pouring and transferring natural materials, sorting loose parts by texture or weight, and exploring wooden percussion instruments are simultaneously Montessori activities and rich sensory play experiences. The two complement each other when combined intentionally, Montessori provides structure and skill progression, sensory play provides regulatory input and open-ended exploration.
What makes a toy Montessori?
A Montessori toy is typically made from natural materials, has a single clear purpose isolating one skill or concept, is self-correcting where possible, and invites purposeful independent use rather than passive entertainment. By these criteria, many products marketed as Montessori are not and many not marketed as Montessori genuinely are.
Is kinetic sand Montessori?
Not in the strict sense. Kinetic sand is a rich sensory play material but does not meet traditional Montessori criteria it lacks a specific isolated skill purpose and self-correcting design. Many Montessori-informed educators include it as a sensory regulation tool, particularly for children who benefit from tactile input before engaging with more structured Montessori work.
What is the Montessori approach to messy play?
Montessori is not anti-mess, but deliberate about it. Mess is a consequence of purposeful activity, not the point of the activity. Traditional Montessori practice also emphasises care of the environment, learning to clean up and maintain order, as a developmental goal in itself.
Are sensory bins Montessori?
Sensory bins are not traditional Montessori materials, but they are not incompatible with a Montessori-informed environment. A sensory bin presented on a tray with limited purposeful tools at child height, with an expectation that the child returns materials after use, meets many Montessori environmental principles even if the activity itself is more open-ended.
What are the benefits of Montessori play?
Research consistently finds benefits in executive function, self-regulation, reading, mathematics and social cognition, primarily through Montessori's emphasis on intrinsic motivation, self-directed work and error correction.
What are the benefits of sensory play?
Sensory play supports neural development, sensory processing, emotional regulation, fine motor development, language acquisition and social skills and is particularly beneficial for children with sensory processing differences, autism spectrum disorder or developmental delays.
Is Montessori better than other approaches?
The research suggests Montessori produces strong outcomes across multiple developmental domains, but better depends entirely on the child, the context and the quality of implementation. The most effective early childhood environments draw deliberately from multiple frameworks rather than committing exclusively to one.
