If you’re looking for a simple activity that combines sensory play, fine motor practice, and imaginative play, this Hungry Caterpillar Sensory Bin is a perfect choice! Kids will love searching for colorful foods and “feeding” them to their hungry caterpillar while strengthening important developmental skills.
This activity is easy to set up, uses inexpensive materials, and can be adapted for toddlers, preschoolers, kindergarteners, therapy sessions, classrooms, or play at home.
One of the best things about sensory bins is that they naturally encourage kids to explore with their hands while keeping them engaged for long periods of time. Adding a simple fine motor challenge – like threading pictures onto a pipe cleaner – takes the activity one step further by strengthening the small muscles of the hands needed for writing, dressing, cutting, and other everyday tasks.
What You’ll Need:
-Plastic sensory bin or shallow storage container
-Sensory filler (choose one):
-Dry beans
-Laminated pictures of foods (see form below)
-Hole punch
-Green pipe cleaners cut into smaller pieces
What to Do:
1. Print and laminate pictures of different foods.
2. Punch a hole in each picture.
3. Fill your sensory bin with dry beans.
4. Hide the food pictures throughout the bin.
5. Tie the pieces of green pipe cleaner onto a piece of string. Add a piece of card stock to the end of the string as a stopper.
As children dig through the sensory bin, they’ll search for each piece of food. Every time they find one, they’ll “feed” the hungry caterpillar by threading it onto the pipe cleaner.
Keep searching until all of the foods have been eaten!
Developmental Skills Addressed
Although this activity feels like simple play, it targets many important developmental skills.
Fine Motor Skills
Threading the food pictures onto a pipe cleaner requires children to coordinate the small muscles of the hands and fingers while stabilizing the opposite hand.
Bilateral Coordination
Kids use both hands together – one hand holds the pipe cleaner while the other hand positions the food picture.
Pincer Grasp
Picking up the laminated pictures encourages children to use the thumb and index finger together, an important grasp pattern for many daily activities.
Hand-Eye Coordination
Children must visually guide the hole onto the pipe cleaner, strengthening visual motor integration.
Visual Scanning
Searching through the sensory bin encourages children to visually locate hidden objects among other materials.
Sensory Processing
Digging, scooping, and exploring different textures provides rich tactile sensory input while encouraging exploration and engagement.
How to Change It Up:
-As children become more successful, try increasing the challenge.
Hide only specific foods and ask children to find them in order.
Name a food and have children search for it.
Thread the foods in the same sequence as the story.
-Add More Gross Motor Play
Want to get kids moving? Instead of hiding all of the foods in one sensory bin, hide them around the room. Children can:
Crawl to each food.
Bear walk between hiding spots.
Crab walk back to the caterpillar.
Hop like a caterpillar.
Tiptoe to collect each food.
Complete an obstacle course before feeding the caterpillar.
-Caterpillar Relay
Scatter the food pictures around the room. One child at a time races to find a food, brings it back, and threads it onto the class caterpillar before the next player goes.
