At age 8, children typically experience significant growth in their cognitive and social skills. They become more independent and can engage in complex conversations. Their ability to think logically improves, allowing them to solve problems and understand basic math concepts. Socially, 8-year-olds often form stronger friendships and may start to show preferences for certain activities or hobbies, such as sports or arts. They also begin to understand the importance of teamwork and cooperation, which can be seen in group activities at school or in extracurricular programs.
