At age 7, children typically experience significant growth in their cognitive and social skills. They become more independent and can express their thoughts and feelings more clearly. This age often marks the beginning of formal education, where children learn to read and write, and develop basic math skills. Socially, 7-year-olds start to form friendships and understand the importance of teamwork. They enjoy playing games and participating in group activities, which helps them learn cooperation and sharing. This stage is crucial for developing emotional intelligence and understanding social norms, laying the foundation for future relationships.
