Concept Development: Building Blocks of Learning for Children

Last updated on:

Every child enters the world ready to learn – but how they learn varies greatly. For children with intellectual disabilities, the process of building knowledge doesn’t begin with textbooks or worksheets. It begins with touch, sound, sight, smell, and taste. Concept development – the ability to form mental categories and generalizations about the world – is the very foundation of all learning. Understanding how this process unfolds, and how teachers can actively support it, makes an enormous difference in the classroom and beyond.

How we develop concepts

Concept formation is not an abstract or mysterious process. It begins with the most basic human activity: perceiving the world through the senses. When a child touches a rough stone, hears a dog bark, or watches water pour from a cup, those sensory inputs create mental images – internal representations of the world. Over time, the mind begins to compare these images, identify what is common among them, and group them into categories.

This is how a child comes to understand what a “horse” is. First, they see one horse – perhaps at a farm or in a picture book. Then they see another, and another. Each horse is different in color, size, and posture, yet the child’s brain begins to recognize shared features: four legs, a mane, a particular body shape. Gradually, the child moves from a specific instance to a general concept. This movement from the particular to the general is the core of concept formation, and it underlies all future learning.

Jean Piaget’s foundational work on cognitive development helps explain this process. According to Piaget, children process new information by balancing two mental actions: assimilation (fitting new information into an existing mental framework) and accommodation (adjusting that framework when new information doesn’t fit). For children with intellectual disabilities, both these processes take longer and require more deliberate support – but they absolutely do occur.

Research in concept development shows that by around age 3, typically developing children can already categorize objects based on abstract semantic categories – grouping “animals” as distinct from “furniture,” for instance. For children with intellectual disabilities, concept formation is a critical prerequisite skill that must be explicitly assessed and taught, as deficits in categorization are commonly observed across a range of neurodevelopmental disabilities including Down syndrome and autism spectrum disorder.

Factors to consider when teaching concepts

Knowing that concept formation depends on sensory input and mental comparison is one thing. Translating that into effective classroom practice is another. Teachers working with children who have intellectual disabilities need to be especially thoughtful about how they introduce and sequence concept-based learning.

Start with the concrete, not the abstract

The single most important principle in teaching concepts to children with intellectual disabilities is to start with concrete, hands-on experiences. Hands-on learning is especially effective for students with intellectual disabilities because concrete experiences make abstract ideas understandable and promote active participation. Rather than telling a child what a vegetable is, place real carrots, beans, and tomatoes in front of them. Let them hold, smell, and examine each one.

When introducing a new concept, begin with examples that are strikingly different from each other before moving to subtle distinctions. A child learning the concept of “big and small” should first compare a large watermelon to a tiny grape – not two differently sized apples. The contrast needs to be obvious enough to register before fine distinctions are introduced.

Limit choices and secure attention

Presenting too many options at once can overwhelm a child with intellectual disabilities. Children with intellectual disabilities often need more time and repetition to master new skills, and flooding them with information undermines the very learning you’re trying to support. Start with two choices, then gradually expand to three or four as confidence grows.

Equally important is securing the child’s attention before instruction begins. A child who is distracted or dysregulated cannot effectively process new concept information. Simple attention cues – a tap on the table, a familiar song, or eye contact – can serve as effective anchors before a lesson begins.

Use repetition and a central theme

Repetition is not just helpful for children with intellectual disabilities – it is essential. Children with intellectual disabilities need to encounter a concept in different ways and have the opportunity to practice it many times in order to learn and remember it. This is not a sign of failure; it reflects the reality of how their brains consolidate new information.

One particularly effective approach is organizing instruction around a central theme. Take “vegetables” as an example. A single theme like this allows a teacher to simultaneously teach color (“the carrot is orange”), shape (“the bean is long and thin”), size (“the pumpkin is bigger than the pea”), and texture (“the cucumber feels smooth”) – all within a single, coherent learning context. Thematic teaching reduces cognitive load while expanding the range of concepts being developed.

The role of multi-sensory learning

Multi-sensory instruction – engaging sight, hearing, touch, smell, and even taste simultaneously – has strong research support as an approach for children with disabilities. Purposeful sensory experiences have a direct impact on learning, motivation, and self-regulation in children with disabilities, and teachers who understand sensory processing patterns are better equipped to support concept development throughout the school day.

A case study on multisensory teaching for a child with intellectual disability found that using visual, tactile, kinesthetic, and auditory drills together significantly increased participation and retention. The child showed improved attention and was better able to remember and apply new learning after experiencing information through multiple senses simultaneously.

Multisensory instruction is based on the concept of “whole brain learning”, which holds that the most effective instruction occurs when multiple brain regions are activated at once. For concept development specifically, this means pairing a verbal label (“this is round”) with a tactile experience (holding a ball), a visual cue (seeing the shape drawn), and a physical action (rolling it across the table). Each additional sensory channel reinforces and deepens the concept being formed.

Developing prerequisite cognitive skills

Before a child can effectively acquire concepts, certain foundational cognitive skills need to be in place. These are the building blocks that make concept formation possible – and for children with intellectual disabilities, they need to be deliberately nurtured rather than assumed.

Matching

Matching is the most basic of these skills. It involves recognizing that two things are the same. Matching tasks – pairing identical socks, finding two red blocks, placing a picture next to its real-world object – train the brain to make the critical comparison between items. Matching represents the most basic level of concept formation, and it is the starting point from which all more complex categorization develops.

Identifying similarities and differences

Once matching is established, children can begin to notice not just what is the same, but what is different. This skill – comparing items along a dimension like color, shape, or size – is the engine of concept formation. Without it, a child cannot group things into categories or distinguish one class of objects from another.

Classifying

Classification is the skill of sorting or grouping items by shared characteristics. Children naturally begin to classify by sorting toys by type or grouping crayons by color, typically around ages 3 to 4. For children with intellectual disabilities, classification develops more slowly, but it does develop – and connecting new objects to ones the child already knows is a key strategy. Research has found that living experience can help children with intellectual disabilities improve their classification ability, which is why linking classroom activities to familiar everyday situations is so effective.

Comparing and seriating

Comparing involves judging two or more things against each other – bigger/smaller, heavier/lighter, louder/quieter. Seriation takes this further by arranging objects in a sequence – shortest to tallest, lightest to darkest. Seriation requires the ability to see differences and compare multiple objects simultaneously, making it a more advanced skill that builds on earlier matching and comparing experiences. Activities like arranging cups by size or sequencing story picture cards help develop this ability in a hands-on way.

All of these prerequisite skills are most naturally developed through sensory play and daily interactions – sorting laundry, setting the table, lining up shoes by size, or organizing fruit at mealtimes. The classroom can mirror these everyday contexts deliberately, making concept development feel natural rather than forced.

Why getting this right matters

Concept development is not just an academic milestone – it is the scaffolding on which all other learning is built. A child who cannot form and use concepts will struggle to understand language, follow instructions, solve problems, or navigate daily life. For children with intellectual disabilities, the stakes are especially high because early and accurate support can significantly improve a child’s ability to learn and function.

The good news is that children with intellectual disabilities are absolutely capable of developing concepts – they just need more time, more repetition, and more intentional teaching. When teachers understand the process of concept formation, sequence instruction thoughtfully, use multisensory approaches, and build prerequisite skills systematically, they lay the groundwork for genuine and lasting learning.

What do you think? When you consider the children you work with or care for, which prerequisite skill – matching, classifying, comparing, or seriating – do you find most challenging to teach in an engaging way? And how might organizing lessons around a single central theme, like “fruits” or “clothing,” change the way a child with intellectual disability experiences concept learning?
