Visual, tactile and auditory experiential activities

This is a wooden educational tool with a smooth, rounded-corner, square shape. 

There is a small round hole in the center, allowing you to see a bell inside. 

When a child shakes or taps this wooden block, the bell produces a sound. 

This design is often used in Montessori education to help young children explore and perceive sound through auditory and tactile experiences, promoting sensory development.
