Schoolchildren are young individuals who attend school to receive an education. They typically range in age from about 5 to 18 years old and are enrolled in various grades, depending on their age and academic progress. Schoolchildren learn a variety of subjects, including math, science, language arts, and social studies, which help them develop essential skills for their future. In many countries, schoolchildren are required to attend school until a certain age, often around 16 or 18. They participate in activities such as sports, music, and art, which contribute to their overall development. Schoolchildren also interact with their peers and teachers, fostering social skills and teamwork.
