5 Easy Sensory Play Activities Using Loose Parts Kits for Toddlers

Sensory play is more than just messy fun — it's how toddlers make sense of the world. When you pair sensory play with loose parts, you give your child the freedom to sort, stack, scoop, and explore at their own pace. Loose parts are open-ended materials that can be moved, combined, and transformed in countless ways, making them perfect for curious little hands.

The best part? You don't need a lot of fancy equipment. A simple set like the Guidecraft Traveling Treasures Discovery Lab or a collection of Treasure Blocks can become the foundation for hours of rich, hands-on learning. Here are five easy sensory play activities using loose parts kits that you can set up in minutes.

1. Texture Treasure Bin

Fill a shallow bin with a base material like dry rice, sand, or oatmeal. Add a handful of Treasure Blocks — each block contains a different natural or man-made object inside, from seashells to colored beads. Toddlers love shaking the blocks to hear the sounds, then digging through the bin to find and match them. This activity builds tactile awareness and encourages cause-and-effect exploration.

To extend the play, add scoops, small cups, and tongs. Your child can practice transferring the blocks from one container to another, strengthening hand muscles and coordination. The transparent windows of the Treasure Blocks let kids see the hidden treasures, which adds a visual discovery layer to the sensory bin.

• Use a shallow bin to keep spills manageable and let toddlers reach everything easily.

2. Discovery Stacker Towers

Loose parts kits often include rings, cylinders, and discs that are perfect for stacking. Set out a few of these pieces along with a wooden base or a simple tray. Show your toddler how to stack the rings from largest to smallest, then let them experiment with their own patterns. The open-ended nature of loose parts means there's no right or wrong way to build.

This activity naturally supports early math concepts like size comparison, sequencing, and balance. As your child stacks and knocks down towers, they're also learning about gravity and cause and effect. The Traveling Treasures Discovery Lab includes a variety of shapes and textures that work beautifully for this kind of exploratory building.

• Keep a small basket nearby so your child can sort pieces by size or color before stacking.

3. Scoop and Pour Sensory Bin

Fill a bin with a loose filler such as colored pasta, water beads, or kinetic sand. Add a scoop, a funnel, and a few small containers. Toss in a few pieces from a loose parts kit — like the wooden discs or cylinders from the Traveling Treasures Discovery Lab — and let your toddler scoop, pour, and transfer. This simple setup builds fine motor control and hand-eye coordination.

The repetitive motion of scooping and pouring is deeply calming for many toddlers. It also introduces early concepts of volume and measurement. If you use water beads, the squishy texture adds a delightful sensory surprise. Just be sure to supervise closely with small items and water beads to keep play safe.

• Swap the filler each week (rice, beans, sand, oats) to keep the activity fresh and engaging.

4. Nature Hunt Loose Parts Play

Take the loose parts kit outdoors! Gather natural treasures like pinecones, smooth stones, leaves, and acorns. Combine them with a few pieces from your kit — such as the wooden rings or blocks from the Treasure Blocks set — and let your toddler sort, stack, and arrange them on a tray or in a shallow bin. This activity connects sensory play with nature exploration.

Outdoor loose parts play encourages observation and classification. Your child might group items by color, size, or texture. They can line up stones next to wooden discs or stack leaves inside a ring. The Martha Stewart Kids' Outdoor Couch, Chair and Low Table Set provides a perfect low surface for this kind of outdoor sensory play, keeping everything within easy reach.

• Bring a small basket or bucket so your child can collect their own natural treasures during a walk.

5. Sound and Shake Exploration

Fill a few small, sealable containers with different materials — rice, bells, beads, sand — and add them to a sensory bin along with your loose parts kit. Toddlers can shake, rattle, and roll each container to discover the different sounds. The Treasure Blocks are especially fun here because each one already has a unique sound inside.

This activity supports auditory discrimination and language development as you name the sounds: 'That's a soft shake' or 'Listen to the jingle!' You can also pair the sound containers with the wooden discs and cylinders from your kit, letting your child tap them together to create rhythms. It's a simple, screen-free way to explore music and sound.

• Use clear containers so your child can see the materials inside and connect the visual with the sound.

Sensory play with loose parts doesn't have to be complicated or expensive. With just a few open-ended materials — like the Traveling Treasures Discovery Lab or a set of Treasure Blocks — you can create rich, engaging experiences that support your toddler's development. Try one of these activities this week and watch your child's curiosity come alive.
