The Complete Guide to Sensory Filling Trays: What They Are and Why Children Love Them
If you've spotted sensory filling trays on social media and wondered what all the fuss is about, you're in the right place. These simple little trays have become a staple in nurseries, classrooms, and homes across the UK — and for good reason.
As a nursery practitioner myself, I use sensory trays with children every single day. Here's why they work so well and how to get started at home.
What Is a Sensory Filling Tray?
A sensory filling tray is a shaped tray with recessed areas that children fill with materials like dried rice, oats, lentils, sand, or even water beads. Think of it like a colouring book, but instead of crayons, children use scoops, spoons, and their fingers to fill in the shapes.
The trays sit flat on a table or inside a Tuff Tray, keeping the mess contained while little hands get busy.
Why Children Love Them
There's something deeply satisfying about filling a shape — even adults find it hard to resist! For children, the appeal is immediate:
- It's open-ended play — there's no wrong way to do it
- It's tactile — different filling materials create different sensory experiences
- It's calming — the repetitive scooping and pouring is naturally soothing
- It tells a story — themed trays (animals, vehicles, weather) spark imagination
What Skills Do They Build?
This is where sensory trays really shine. Behind the fun, children are developing crucial early years skills:
- Fine motor control — scooping, pinching, and pouring strengthen the small muscles needed for writing
- Hand-eye coordination — aiming materials into specific shapes takes concentration
- Mathematical thinking — concepts like full, empty, more, less, counting, and sorting happen naturally
- Language development — themed trays prompt conversation, storytelling, and new vocabulary
- Focus and patience — completing a tray from empty to full builds attention span
How to Set Up a Sensory Tray at Home
You don't need much to get started:
1. Choose Your Tray
Pick a theme your child is interested in. Animals, vehicles, weather, and seasonal shapes like Easter bunnies or Christmas trees all work brilliantly. Our sensory filling tray collection has over 30 designs to choose from.
2. Pick Your Filling Material
Start with what you have in the kitchen cupboard:
- Dried rice — the classic choice, easy to scoop and pour
- Porridge oats — softer texture, great for younger children
- Dried lentils or chickpeas — a different feel and sound
- Kinetic sand — mouldable and mess-free
- Coloured rice — add a few drops of food colouring to a bag of rice, shake, and dry on a tray
3. Add Tools
Scoops, spoons, tweezers, and pouring jugs all add to the experience. Different tools challenge different grip patterns.
4. Let Them Lead
Resist the urge to direct. Put the materials out and step back. You'll be surprised how long children will stay engaged when they're in charge of their own play.
Sensory Tray Ideas by Age
- 12-18 months: Large trays with oats or rice. Focus on scooping and tipping. Always supervised.
- Themed trays with coloured rice. Introduce scoops and small containers.
- Combine multiple trays for storytelling setups. Add tweezers for a fine motor challenge. Use trays for counting and sorting activities.
Tips From a Nursery Practitioner
- Contain the mess — put everything inside a Tuff Tray or on a large baking sheet. A sheet under the table catches the rest.
- Rotate themes — swap trays every week or two to keep things fresh
- Follow their interests — if your child is obsessed with dinosaurs, use dinosaur trays. Engagement follows interest.
- Make it seasonal — Easter trays in spring, weather trays in autumn, Christmas shapes in December. It connects play to the real world.
Why Our Trays Are Different
All of our sensory filling trays are 3D printed in the UK using PLA plastic — a plant-based, biodegradable material made from renewable resources like cornstarch. They're non-toxic, lightweight, and tough enough for daily use in a nursery setting.
Every tray is designed and printed by hand in our workshop, which means we can offer shapes you won't find anywhere else.
