The Prentice Hall Literature textbook your received is typical of English curricula across the country. (Prentice Hall packages this textbook with a grammar book and an additional literature only text that can be used as a supplement. The literature only book does not include activities like Vocabulary Development Lesson, Grammar Lesson, Extension Activity.)
It is not unusual for classroom teachers to be given only the Literature book. And the text represents the district’s English curriculum.
