I Piagets kognitiva utvecklingsteori, konkret operationsstadium hänvisar till de tidiga stadierna av kognitiv utveckling där barn börjar utveckla förmågan att utföra konkreta uppgifter. I detta skede, barn använder abstrakta begrepp som siffror, former, och mönster för att lösa problem.

Ett exempel på en uppgift som faller under det konkreta operativa skedet är att räkna. I denna ålder, barn börjar räkna föremål genom att placera dem på ett rutnät eller en serie cirklar. De kan också börja räkna med en mängd olika gester, som att peka eller göra ett ljud.
Ett annat exempel på en uppgift som faller under det konkreta operativa skedet är problemlösning. Children at this stage begin to use abstract concepts such as logic and reason to solve problems. Till exempel, they might come up with a solution to a math problem by breaking it down into smaller steps and using logical reasoning to arrive at the correct answer.
Slutligen, there is the stage of preoperational stage which is when children are at an earlier stage of cognitive development than concrete operational stage. The preoperational stage is characterized by the use of symbols and rules of organization. At this stage, children use objects and simple forms such as shapes, lines, and colors to represent information and solve problems.
The benefits of doing addition and subtraction in the preoperational stage include developing important skills such as understanding cause-and-effect relationships, identifying similarities and differences between things, and organizing information in a way that makes sense. These skills are crucial for success in many areas of life, including education, företag, and social interaction.

Dock, it is important to note that some research suggests that children may not develop all aspects of these cognitive abilities until later in life. Dessutom, early exposure to mathematical concepts and formal instruction in arithmetic can help to facilitate the development of these skills in early childhood. Total, while addition and subtraction may not yet be fully developed in the preoperational stage, they play an important role in helping young children develop important cognitive skills that will serve them well throughout their lives.
