Piaget believed that until about age 6, it is difficult for children to think?

Yes, obviously at that age children of 6 years are developing their celebratory although there are some developed children who can think more clearly even as an adult, but most find it difficult to think at that age, example: yes to a child of 6 years you ask about a math problem that is studying will take a long time to answer even tell you the years you have and I'll tell you with your fingers, I hope you have helped.
