A teacher’s edition is a special version of a textbook designed to help instructors better teach the material. According to AbeBooks, teacher’s editions are nearly identical to the student editions, but they include extra notes and resources and often provide answers to problems or assignments given in the textbook.
A teacher’s edition of a textbook may have a different international standard book number (ISBN) than the student or regular edition. It may also include the words “Teacher's Edition” in the book title.
Although teacher’s edition textbooks are designed for instructors, they are sometimes used by students who are looking for extra help in a course. They can be useful for parents who are home-schooling their children or for distance-learning students.
