Water Tray Accessories for Schools: What to Buy for EYFS and KS1

Water play is one of the most valuable and heavily used areas of continuous provision in Early Years and Key Stage 1. From exploring capacity and developing mathematical language to strengthening fine motor skills and encouraging scientific enquiry, a well-resourced water tray can support multiple areas of learning simultaneously. However, creating an effective water play area is not about filling a tray with as many toys as possible. The most successful provisions are built around durable, open-ended resources that encourage exploration, support curriculum outcomes and continue delivering value throughout the school year.

Why is water play so important in EYFS and KS1?

Few resources offer the same combination of sensory exploration, problem-solving and curriculum opportunities as water. For young children, water provides immediate opportunities to investigate:

• Capacity
• Volume
• Cause and effect
• Floating and sinking
• Movement and flow
• Early scientific enquiry

In EYFS, water play supports many areas of the EYFS Framework, including Mathematics, Understanding the World, Physical Development and Communication and Language. As children move into Key Stage 1, those same experiences begin to connect more explicitly to the National Curriculum through measurement, observation, prediction and simple investigations.

Through its work with schools across the UK, GLS regularly sees water play providing some of the richest opportunities for exploration, investigation and independent learning. The most effective water trays encourage children to test ideas, solve problems and make discoveries through hands-on experiences rather than direct instruction.

What water tray accessories do schools actually need?

One of the most common mistakes schools make is overcomplicating water provision. Effective water play does not require dozens of themed toys or expensive activity kits. Instead, the most successful setups focus on a small number of open-ended resources that can be used in multiple ways.

Jugs, scoops and funnels

These remain the foundation of most water play areas. They support:

• Capacity exploration
• Pouring and transferring
• Vocabulary development
• Hand-eye coordination

Simple resources often generate the richest learning opportunities.

Tubing and channels

Flexible tubing, gutters and water channels encourage children to investigate:

• Flow
• Direction
• Gravity
• Problem-solving

These resources also support collaborative learning as children work together to create systems and pathways.

Measuring equipment

As children move through EYFS and into KS1, introducing more precise measuring tools can deepen learning. Examples include:

• Graduated jugs
• Measuring cylinders
• Calibrated beakers
• Water scales

These resources help bridge the gap between exploratory play and more structured mathematical understanding.

Water wheels and flow resources

Simple mechanical resources help children observe movement, force and cause-and-effect relationships in action. The most durable options are often the simplest, with fewer moving parts and greater longevity.

How can schools choose water play resources that last?

Schools often underestimate how demanding water play can be on resources. Equipment may be used daily, stored outdoors, exposed to sunlight, subject to repeated washing, and handled by large numbers of children. This is why durability matters.

When supporting schools with resource planning and outdoor provision, GLS often finds that open-ended resources made from robust plastics or stainless steel provide the strongest long-term value. Durable resources reduce replacement costs, support consistent provision and help schools maximise their budgets over multiple academic years.

When selecting resources, schools should consider:

• Easy cleaning: Resources with simple designs are quicker to clean and dry.
• Durable construction: Heavy-duty materials often outlast cheaper alternatives many times over.
• Open-ended use: The more ways a resource can be used, the greater educational value it delivers.
• Curriculum flexibility: Resources that support multiple areas of learning often provide better long-term return on investment.

The aim is not necessarily to buy more resources. It is to choose resources that remain useful year after year.

How many accessories should be in a water tray?

More resources do not automatically create better learning. In fact, many practitioners find the opposite. When water trays become overcrowded, children can become distracted and move rapidly between activities without engaging deeply in any one experience.

Many experienced Early Years practitioners recommend limiting provision to a focused collection of complementary resources. For example:

• Funnels
• Clear jugs
• Tubing
• Measuring containers
• Water wheels

This encourages sustained exploration while reducing setup and tidy-up time.

How can schools reduce water play workload?

An effective water area should inspire learning, not create unnecessary maintenance for staff. Simple routines can significantly reduce workload.

• Use draining storage: Perforated baskets or mesh storage containers allow water to drain naturally and improve airflow.
• Rotate resources: Rather than purchasing new kits throughout the year, schools can refresh provision by rotating existing resources and introducing new challenges.

Change the learning focus

The same water tray can support very different experiences by:

• Adding ice
• Introducing coloured water
• Exploring floating and sinking
• Creating measuring challenges
• Investigating flow and movement

These small changes often have a greater impact than purchasing additional equipment. Clearly organised resources encourage children to access and tidy away equipment independently, reducing demands on adults.

How does water play support maths and science?

Water play creates some of the most meaningful opportunities for hands-on learning.

Mathematics

Children naturally explore:

• Full and empty
• More and less
• Capacity
• Estimation
• Measurement
• Comparison

These concepts become easier to understand because children experience them directly.

Science

Water also supports early scientific enquiry through:

• Observation
• Prediction
• Testing
• Investigation
• Cause and effect

Children quickly begin asking questions, making predictions and testing ideas through play. This combination of mathematical and scientific learning is one reason water provision remains such a valuable part of both EYFS and KS1 environments.

Why does practical support matter when developing water provision?

Creating an effective water play environment is rarely a one-off decision. As cohorts change, curriculum priorities evolve and resources wear over time, schools often review how their provision is being used and where improvements can be made.

GLS works with schools to help them make informed decisions about learning resources, durability, classroom organisation and long-term value. Whether schools are refreshing an existing water area or developing a new provision space, practical guidance can help ensure resources continue supporting learning year after year.

This reflects the wider Findel approach of supporting educational outcomes rather than simply supplying products. Schools increasingly value partners who understand how resources are used in practice and can help them make confident decisions that support both learning and budgets.

Creating meaningful learning through water play

The best water play areas are not necessarily the largest or most expensive. They are the ones that encourage curiosity, investigation and independent thinking. By choosing durable, open-ended resources and focusing on quality rather than quantity, schools can create water provision that supports learning across multiple curriculum areas while delivering excellent long-term value.

At GLS, we know that some of the richest learning experiences come from simple resources used thoughtfully. A well-planned water tray can help children develop mathematical understanding, scientific thinking, communication skills and confidence through exploration and discovery. When supported by durable resources, effective organisation and practical guidance, water play becomes far more than a sensory activity—it becomes a powerful foundation for learning.
