The Simple Steps to Sentence Sense for High School and the new Simple Steps to Sentence Sense for Middle School contain exactly the same lesson notes, lesson pages, and overhead projection pages, HOWEVER, the group practice exercises, individual practice exercises, writing connection exercises, and tests are different in each book.
This new book combines the lesson notes, student lesson pages, and overhead projection pages that are in Sentence Simple Steps to Sentence for High School with all new group practice exercises, individual practice exercises, writing connection exercises, and tests.
Also, because this book is designed to be used with middle school students, it does not include the advanced steps to be used to prepare for Advanced Placement Exams.
Of course, the answers are provided to make your job easier.
If you already have a copy of Simple Steps to Sentence Sense for High School, then you may wish to purchase the Simple Steps to Sentence Packet of exercises, tests, and writing connection pages instead of this book.
