According to Piaget’s theory, what is a primary developmental stage for children in grades K-6?

The Concrete Operational Stage is a primary developmental stage for children in grades K-6 according to Piaget’s theory. This stage typically occurs between the ages of 7 and 11 years, which aligns well with the age range of children in grades K-6. During this time, children begin to think logically about concrete events and develop skills in reasoning, understanding the concept of conservation, and grasping the relationships between objects. They can perform operations on concrete objects and understand the concept of reversibility, which allows them to mentally manipulate information.

This stage also marks a shift from egocentric thinking, where children see the world solely from their own perspective, to a more balanced viewpoint that takes the perspectives of others into account. Children begin to categorize objects, understand seriation (the ability to arrange items in order), and recognize that certain properties of objects remain the same despite changes in form or appearance.

In contrast, the other stages mentioned focus on different age groups or developmental capacities that are not primary for the K-6 range. The Preoperational Stage, which occurs from approximately 2 to 7 years, is marked by symbolic thought but lacks the logical operations present in the Concrete Operational Stage. The Formal Operational Stage emerges around the age of
