This is the second stage of Piaget’s theory of development. Children enter this stage at age two and continue through age six or seven.

During this stage, children’s minds are developing at a fast pace and their thinking abilities are broadening. Children are now beginning to think and talk outside of simple experience however, they are not able to think and reason logically yet.

Milestones of the Pre-Operational Stage:

  • Able to use language to describe images and words about certain objects
  • Able to classify objects by grouping them (grouping all the blue blocks together etc.)
  • Extensive Pretend Play- children are able to dramatize their play time (playing doctor or mommy)
