What age range does Piaget's pre-operational stage cover?

Piaget's pre-operational stage is characterized by cognitive development that occurs from approximately 2 to 7 years of age. During this stage, children begin to engage in symbolic play and learn to manipulate objects, but they do not yet understand concrete logic. They are egocentric, meaning they struggle to see things from perspectives other than their own. This is a crucial stage for language development, imagination, and the beginning understanding of concepts like time and numbers, although the reasoning is still intuitive rather than logical. The age range reflects significant milestones in cognitive development, making it an essential period for educators and caregivers to support learning through imaginative and interactive play.
