🔎 Explanation

Key Concepts

• Reversibility: In the Concrete Operational Stage (ages 7–11 years), children understand that objects can be changed and then returned back to their original form. Example: 2 + 3 = 5 and 5 - 3 = 2.
• Serialization: Children develop the ability to arrange objects logically in order (like smallest to largest), which is a skill of the concrete operational stage.
• Conservation: Children realize that quantity remains the same despite changes in shape or appearance — a major achievement of this stage. 
• Animism: This refers to believing that non-living objects have feelings and consciousness, which is seen during the preoperational stage (2–7 years)

2. Preoperational
3. concrete operational
4. formal operational. 

1. Sensorimotor Stage (Birth to 2 years): Children learn through sensory experiences and motor actions, focusing on understanding their environment through actions like grasping, sucking, and exploring objects. 
2. Preoperational Stage (2 to 7 years): Children begin to use symbols and language, developing their ability to think and represent the world through mental images and language. They may also engage in pretend play. 
3. Concrete Operational Stage (7 to 11 years): Children can think logically about concrete events and apply operations like addition, subtraction, and multiplication. They can also solve problems using logic and begin to understand conservation. 
4. Formal Operational Stage (12 years and older): Individuals can think abstractly and reason about hypothetical situations, using deductive reasoning to solve problems. They can also consider different perspectives and engage in complex thought processes.
