Concrete Operational Stage: Piaget's Theory of Cognitive Development

Children ages 8-11 are under this stage. On this stage, children have the ability to think logically. However, this only includes those concrete objects and the things they can perceive using their senses. Unlike the prior stage, concrete operational children no longer concentrate on one aspect or feature. Rather, they already know how to observe and to look at the other details of a person, an object and even a situation. In addition, children on this stage can now reverse their thinking. At last, if I will get a chance to teach a concrete operational child, I will now find it easy to teach the commutative property of addition and multiplication. Just a review, commutative property states that A+B is the same with B+A, or AxB is equal to BxA. In real life situation, this can be seen if a child now understands that he will have high grades if he studies his lesson and if he studies his lesson, he will have high grades.
Furthermore, children now have the ability to seriate, or to order or arrange things based on given criterias whether these will be on shape, size, color, etc. Lastly because of the above mentioned characteristics, a concrete operational child knows how to conserve. This is the ability to know that their are certain properties that do not change even there is a change in appearance. For example, a paper will still a paper even if it was crumbled, torn or cut. Or going back to Piaget's experiment on the glasses, a concrete operational child can already identify that the amount of water is equal even the two glasses are not identical.
