The age range of 5 to 18 years encompasses a significant period of childhood and adolescence. During this time, children typically progress through various stages of development, including early childhood, middle childhood, and adolescence. They experience physical, emotional, and cognitive growth, which is crucial for their overall development. Education plays a vital role in this age group, as most children attend elementary school from ages 5 to 11, followed by middle school and high school until they graduate around age 18. This period is essential for acquiring knowledge, social skills, and preparing for future opportunities.
