You arrange two rows of pennies so they are equal in length. a child views the rows and states that s/he has the same amount of pennies. you spread out the pennies in the bottom row so it is longer than the top row. the child now states that the bottom row has more pennies. this child is in which of piaget's stages?

When the child thinks that after arranging two rows of pennies and then s/he conclude that it is longer than the top row, the child is in preoperational Piaget's stage. This stage also demonstrate that the cognitive development is defined by its egocentric thought, the ability of a person to see things in a different perspective.
