Which, out of the following mentioned activities helps in sensory and cognitive development?

Sensory and cognitive development are crucial aspects of a child's overall growth, and engaging in appropriate activities can significantly contribute to these areas. Various activities are designed to stimulate sensory experiences and enhance cognitive abilities in children. 

Key Points

Engaging in puzzles is a versatile activity that promotes both sensory and cognitive development in children.

• Puzzles require visual-spatial reasoning, problem-solving skills, and hand-eye coordination.
• As children manipulate puzzle pieces, they engage their senses, such as touch and sight, and also enhance their cognitive abilities by recognizing patterns, shapes, and making connections.
• Clay work involves tactile exploration, threading enhances fine motor skills, and tracing supports hand-eye coordination and pre-writing skills. However, puzzles encompass a broader range of cognitive challenges, making them particularly effective for stimulating various aspects of cognitive development.

In conclusion, activities such as clay work, threading, tracing, and puzzles all contribute to sensory and cognitive development in children.
