Preschool teachers develop the language, vocabulary, and interpersonal skills of children ages three through five, though some schools may enroll kids as young as two-years-old. These teachers take on a critical role in the growth of their students and use tools such as interactive play, songs, reading aloud, and repetitive writing to further their development. Much like elementary school teachers, preschool teachers create lesson plans for their students. Most curriculums involve a combination of academics and play-based learning.
