Some Glencoe textbooks provide answers to self-study questions at the end of individuals chapters or at the end of books in student editions. Answer keys for other tests and homework questions can be found in the instructor editions.
Glencoe is a division of McGraw-Hill Education, a major publisher of textbooks for the North American market. Both print and online versions of their textbooks are divided into student and instructor editions. Although some Glencoe texts are intended for self study, and thus include answer keys, most student editions do not include them, as that would enable students to cheat by copying the answer keys into tests and homework assignments without actually learning the material. Instructor online or print editions of Glencoe textbooks are available to instructors who assign the textbooks for their courses, and include substantial amounts of supplemental materials not included in student editions.
