Introducing shapes in play school is crucial for early childhood development. It lays the foundation for cognitive skills as children learn to recognize and differentiate between various shapes. Shape recognition enhances spatial awareness and promotes fine motor skills through activities like cutting and tracing. Incorporating shapes into play also fosters creativity as children engage in imaginative play with geometric forms. Overall, the introduction of shapes in play school provides a fun and interactive way for young minds to explore and understand the world around them.
