Answer: They can use logic, rational thinking and they can produce ideas.
Step-by-step explanation:
The concrete operational stage is the stage where the children usually between ages seven and eleven, in this case, eight, can rationally think and develop their organizations with that thinking. This is the third stage in Piaget's theory.
It means that the children can use logic in those ages for the first time. They can also produce some ideas and they can operate on some objects, events, and situations by their mental possibilities.
