There are three key elements of Piaget's theory: schemas, assimilation, and accommodation.
Schemas are the basic building blocks of cognitive models, and help children form understanding and a mental representation of the world. These are the cognitive framework or category. Example: A child develops a schema for fruits, which includes a watermelon.
Using an existing schema to handle new object or situation. Children perceive and adapt to new information. We often refer to the previous information to interpret the new one. Example: A child finds a strawberry and classify it in the same schema as a watermelon.
The existing schema does not work, and needs to be changed to deal with a new object or situation. Taking new information and altering previously held information to fit in the new information. It establishes how people are going to take in new concepts, schemas, and knowledge.Example: A child finds a pencil and does not fit into the schema of fruits. He creates a new schema for pencil
