Features and Uses:

1. Fine Motor Development: Pushing the balls helps strengthen children's fine motor skills and hand control.

2. Understanding Cause and Effect: Children learn the connection between their actions (pushing the ball) and the result (the ball rolling out).

3. Hand-Eye Coordination: Improves coordination between the hands and eyes.

4. Color Recognition: Helps children identify and differentiate between colors.

This tool is particularly suitable for toddlers aged 1-2 years and is a classic sensory and motor coordination material in the Montessori education system.
