Teachers collaborate with students to provide instruction across a range of subjects. The responsibilities of teachers differ based on the grade level and subject they specialize in. For example, preschool teachers focus on laying the foundation for education by teaching children aged two to four basic concepts like the alphabet, colors, and shapes. As students progress through elementary, middle, and high school, teachers further develop their academic abilities in subjects like grammar, math, science, and history. Additionally, they incorporate lessons on essential life skills, such as effective study habits, to prepare students for higher education and the workforce.
