What are the stages of a child's development in kindergarten and primary school?

In kindergarten and primary school, children are expected to be able to follow certain social rules, gradually develop a sense of responsibility, and begin to fulfill skills such as doing homework. During this period, children may experience symptoms such as not being able to listen to lessons, not being able to sit still, and getting bored quickly while doing homework. In addition, behavioral difficulties such as not being able to maintain friendships and harming their friends may accompany this period. Children may need to be evaluated for disorders such as distractibility, mobility and impulsivity during this period.
