When the preoperational stage ends, the concrete operational begins around the age of seven and would end around the time they turn eleven years old. During the concrete operational stage they would fully understand the theory of conservation and begin to use logic and abstract thinking. Mathematical reasoning is another major development during this stage, for example they would begin to understand that five plus three equals eight, and that eight minus three equals five. Which is also an example of the concept of reversibility another important development in this stage, that most processes are reversible. This stage is a transition period for the children, in this stage the children begin to understand that everyone has their own perspectives, however they wouldn’t be aware of what those perspectives could be, at the end of this stage the children will start to evolve from a egocentric to a sociocentric, and that development in a full sociocentric would be completed in the formal operational stage. The last stage starts at the end of twelve and ends when the person is an
