Twelve-year-olds are typically in the sixth or seventh grade, depending on their birth date and school system. At this age, they experience significant physical, emotional, and cognitive development. Many begin to show greater independence and form deeper friendships, often exploring new interests and hobbies. Academically, twelve-year-olds are usually introduced to more complex subjects, such as algebra and science experiments. They may also start to engage in extracurricular activities, including sports and music lessons. This age marks a transition from childhood to adolescence, where they begin to develop their own identities and opinions.
