Your child has entered middle childhood. Read on for what to expect from your cognitive development at preschool age- to 10-year-old child. By the time your child is 8-years-old, he has firmly entered middle childhood. No longer a wide-eyed novice, he has a great many skills that he will continue to build on to expand his mental abilities in dramatic ways for the next several years.
This ability means that they understand that certain properties of an object will remain the same, even if outward qualities change. For instance, by age 8, children understand that if there are two rows of five pennies, but one is spread so that the pennies are further apart, both rows still have the same total number of pennies. Over the course of the concrete operational period, children also begin to reason more accurately. This realization is in contrast to believing that one row has more simply because it is spread out. Concrete operations is a time when the brain goes through a number of significant changes. Information travels with greater speed through the nervous system and different parts of the brain begin to work in coordination with one another in new combinations.
One result is that children this age begin to make logical arguments. Didn’t I read extra long last week? Similarly, children are able to understand that specific members of a set are also members of the more general set. Are there more dogs or black dogs?

Thus, your child can now more successfully take another’s point of view and can consider more than one dimension simultaneously, as long as the considerations remain concrete. He can more effectively communicate about objects that the listener cannot see, and can think about how others perceive him. In summary, between 8-10 years old, children learn to mentally combine, separate, order, and transform objects and actions. They learn to conserve mass and area, with many also learning to conserve volume.
