The term "school children" refers to young people who are currently enrolled in a school or educational institution. These individuals typically range from ages 5-18, depending on the education system and country they reside in. They attend classes during the day with their peers, learning various subjects such as math, science, history, language arts, and more. School children often have homework assignments to complete outside of school hours, and may participate in extracurricular activities or sports teams after school. The phrase "school children" is commonly used when discussing policies or initiatives that affect the education system, such as funding for schools or programs designed to improve academic performance.
