In Piaget's theory, which stage corresponds with middle childhood?

The Concrete Operations Stage is the correct choice for the period of middle childhood in Piaget's theory of cognitive development. This stage typically encompasses ages 7 to 11 years and marks a significant advancement in children's cognitive abilities. During this time, children begin to think logically about concrete events and can manipulate and understand tangible objects more effectively.

Children in the Concrete Operations Stage develop skills such as the ability to classify objects, understand the concept of conservation (the realization that quantity doesn't change even when its shape does), and apply logical reasoning to specific, concrete situations. This means they can perform operations that involve multiple steps and understand the relationships between different objects or concepts.

This stage is crucial as it reflects a transition from the earlier Preoperational Stage, where thinking is more egocentric and centered around immediate experiences, to the more advanced Formal Operations Stage, where abstract thinking and reasoning begin to emerge. Understanding that middle childhood is characterized by the Concrete Operations Stage helps in recognizing the developmental milestones that children typically achieve during this phase.
