Loose parts are open-ended materials, such as bottle caps, stones, shells, wooden offcuts, fabric scraps, tubes, crates and containers, that children can move, combine, carry, line up, take apart and use in endless ways. A well-designed loose parts collection supports creativity, early maths, language and cooperation, because the materials have no fixed purpose and children must decide what to do with them.
The idea of loose parts sits naturally inside an experiential curriculum such as Global Nexus. It shifts the focus from toys designed for one purpose to materials that invite investigation and invention. It is also inexpensive and sustainable, since many loose parts are collected from everyday life. This guide sets out the theory, the practical steps for building a collection, the safety considerations and the role of adults, for teachers and curriculum leads who want to make loose parts part of their classrooms.
The theory of loose parts
The term comes from the architect Simon Nicholson, who published "How Not to Cheat Children: The Theory of Loose Parts" in 1971. Nicholson argued that in any environment, the degree of inventiveness and creativity, and the possibility of discovery, are directly proportional to the number and kind of variables in it. In other words, children are more creative in spaces with lots of materials they can move and change than in spaces where everything is fixed.
Nicholson was writing about playgrounds and public spaces, but early-years educators quickly saw the connection to classrooms. A room full of single-purpose toys offers a limited range of possibilities; a room with baskets of varied loose materials offers almost unlimited ones. A child with a pile of stones can count them, sort them, build with them, use them as food in role play or arrange them into a pattern, and each of these uses involves a different kind of thinking.
Loose parts connect to many established approaches. They echo the open-ended materials of Reggio Emilia, Froebel's gifts of simple wooden shapes and the heuristic play objects used with toddlers. What unites them is the belief that children's thinking is best supported by materials that leave room for the child's own ideas.
What children learn with loose parts
Loose parts support creativity because children must decide what the materials will become. A cardboard tube can be a telescope, a tunnel, a microphone or a ramp; a piece of fabric can be a river, a cape, a roof or a bed. Making these decisions and acting on them is creative thinking in action, and children often surprise adults with the inventiveness of their ideas.
Early maths runs through loose parts play. Children sort materials by colour, size or shape, count them, compare quantities, create patterns and build structures that require balance and estimation. A child arranging bottle caps in a repeating red-blue-red-blue line is exploring pattern, one of the foundations of mathematical thinking. A child building a tower of wooden blocks is testing balance, height and stability.
Language and cooperation develop too. Children working together with loose parts negotiate what they are building, explain their ideas and solve problems as a group. In a bilingual classroom, these conversations give children reasons to use both languages to describe materials, explain plans and argue about how to proceed. Loose parts also support fine and gross motor skills, as children pick up small objects, carry heavier ones and build large structures outdoors.
Loose parts are also unusually inclusive. Because there is no correct way to use them, children of different ages, abilities and language levels can play side by side and contribute in their own way. A child who is still learning the language of the classroom can join a building project through action before words, and a child who finds structured tasks hard often thrives when the materials leave room for their own ideas. For mixed-age moments and for children who need a gentler way into group play, a basket of loose parts is often the best place to start.
Building a loose parts collection
A loose parts collection grows over time. Many schools start with a few baskets and add to them as they learn what children use. Useful categories include:
- Natural materials: stones, pebbles, shells, seeds, large leaves, sticks, pine cones, coconut shells and wood offcuts. These connect children to nature and vary in texture, weight and shape.
- Recycled materials: bottle caps, cardboard tubes, boxes, clean containers, fabric scraps, corks and lids. Families can contribute these, which builds a connection between home and school.
- Construction materials: wooden blocks, planks, crates, pipes, guttering and tyres, especially for outdoor play where children can build on a larger scale.
- Containers: baskets, bowls, trays, buckets and tins for sorting, transporting and storing materials.
- Fabrics and ropes: lengths of fabric, scarves and soft rope for building dens, defining spaces and role play.
- Metal and reflective objects: spoons, rings, small mirrors with safe edges and tins, which add sound and light to play.
Avoid filling the room at once. A few well-chosen baskets, rotated regularly, give children enough variety without overwhelming the space. Collect materials thoughtfully, clean them before use and remove anything broken or unsafe.
Safety and age suitability
Loose parts require careful attention to safety, especially for younger children. For children under three, every material must be too large to swallow, free of sharp edges and splinters, and non-toxic. Small items such as bottle caps, beads, buttons and seeds are suitable only for older children under supervision, and should be kept out of reach of younger ones in mixed-age settings.
For older children, a risk-benefit approach helps teams decide which materials to offer. Larger materials such as planks, crates and tyres carry some risk of falls or pinched fingers, but they also offer valuable experiences in building, balancing and cooperation. Teams should assess the risks, set clear routines, such as how to carry a plank with a partner, and supervise accordingly, rather than removing every material that carries any risk.
Regular checks are essential. Materials wear out, crack or become dirty, and natural materials can harbour insects or mould, particularly in Ho Chi Minh City's humid climate. Build a simple routine for checking, cleaning and replacing loose parts, and involve children in caring for the materials where appropriate. Children who help wash shells or sort out cracked lids learn to look after shared things.
Storing and presenting loose parts
How loose parts are stored and presented affects how children use them. Materials displayed attractively in low, open baskets or trays, sorted by type, invite children to explore. Materials dumped together in a large box are harder to see and use, and often end up ignored. Clear, consistent storage also makes tidying up easier, as children know where everything belongs.
Presentation can be used to provoke new ideas. A tray of stones placed next to a mirror invites children to explore reflection; a basket of fabric next to some crates invites den building; a collection of tubes beside a ramp invites experiments with rolling. These small arrangements, sometimes called provocations, suggest possibilities without dictating what children must do.
Rotate materials to maintain interest. When a basket is no longer being used, remove it for a while and introduce something new. Observe which materials children return to and which they ignore, and adjust the collection accordingly. Outdoor loose parts may need weatherproof storage, especially during the rainy season, when materials left out can become soaked or damaged.
A worked example: an outdoor building yard
Consider a preschool with a small paved courtyard and a class of five-year-olds who keep trying to build dens with the classroom chairs. The team decides to create an outdoor building yard. Over a month, they collect plastic crates from a local shop, offcut planks sanded smooth by a parent, lengths of guttering, old fabric, rope, large cardboard tubes and a few car tyres. Everything is stored along one wall under a roof, so it stays dry in the afternoon rain.
In the first week, the teachers set a few clear routines: planks are carried by two children, structures above knee height need an adult nearby, and everything goes back to its place at the end. Then they step back. The children build a bus, a shop, a bridge between two crates and a long channel of guttering for rolling balls. Arguments over the longest planks lead to negotiation and turn-taking.
Over the following weeks, the teachers notice children estimating whether a plank will reach, counting crates for a taller tower and explaining their designs in two languages. Two quieter children, who rarely speak in the classroom, become the chief engineers of the bridge. The yard becomes a permanent part of the outdoor day, and the teachers add new materials each month based on what they observe.
The adult's role in loose parts play
With loose parts, the adult's role is to set up the environment, observe, and support without taking over. Resist the urge to show children what to make or to suggest that materials have a correct use. Instead, watch what children do and ask open questions that extend their thinking: "Tell me about what you are building." "What could you use to make it taller?" "What happens if you put this one here?"
Observation is especially valuable with loose parts, because children's choices reveal a great deal about their interests, their thinking and their schemas. A child who repeatedly lines up materials may be exploring order and pattern; a child who wraps objects in fabric may be exploring enveloping. These observations help teachers plan further experiences that build on each child's interests and inform each child's development record.
Adults also help children manage shared materials. Disputes over popular items are common, and they are learning opportunities for negotiation and sharing. Ensuring there are enough materials reduces conflict, and adults can support children in finding solutions rather than imposing them.
Bringing loose parts into the curriculum
Loose parts can be integrated across the curriculum rather than kept as a separate activity. In the maths area, they support counting, sorting and pattern work. In the art area, they become materials for collage and temporary art. In role play, they become food, money, tools and props. Outdoors, larger loose parts support building, balancing and cooperative play on a bigger scale.
Loose parts also connect to monthly themes and projects. During a theme on homes, children might build houses with crates and fabric; during a project on water, they might design channels with guttering and pipes. During a theme on the neighbourhood, they might build a market or a street from boxes and blocks. These uses link open-ended play to the planned curriculum without removing the openness that makes loose parts valuable.
Finally, loose parts support sustainability. Reusing materials from homes and the community teaches children that objects can have many lives, and involving families in collecting materials builds a sense of shared ownership. Review the collection as a team each term, noting what children used, what they ignored and what to add next.

Câu hỏi thường gặp
What are loose parts in early childhood education?
Loose parts are open-ended materials that children can move, combine, arrange and use in many different ways, such as stones, shells, bottle caps, fabric, tubes, crates and wooden pieces. The idea comes from Simon Nicholson's 1971 theory that environments with more movable, variable materials support more creativity and discovery.
Are loose parts safe for children under three?
They can be, if every material is too large to swallow, has no sharp edges or splinters, and is non-toxic and clean. Small items such as beads, buttons and bottle caps are not suitable for under-threes and should be kept out of their reach. Close supervision and regular checks are essential.
Where can a school get loose parts?
Many loose parts are collected rather than bought: natural materials from the garden or park, recycled materials from homes and the school kitchen, and offcuts from local workshops. Families are often happy to contribute. Clean everything before use and remove anything broken or unsafe.
How do loose parts support early maths?
Children naturally count, sort, compare, create patterns and build with loose parts. Arranging bottle caps in a repeating pattern, sorting stones by size or building a balanced tower all involve mathematical thinking. Teachers can extend this with open questions about quantity, size and shape without turning play into a lesson.
How often should loose parts be changed?
Rotate materials when children lose interest, often every few weeks. Observe which materials are used and which are ignored, and adjust the collection accordingly. Introducing a new basket or arranging materials in a new way can revive interest without replacing everything.
Do loose parts replace toys?
Not entirely. Many classrooms keep some well-chosen toys alongside loose parts. But loose parts offer a range of possibilities that single-purpose toys cannot, and many teams find that children spend longer and play more inventively with loose materials than with conventional toys.
