The organization of Step-by-Step Grammar Volume I: Basic Grammar is very different from the majority of grammar books. From the beginning, the sentences are kept simple so that every word may be identified. No word of phrase appears in the exercises until it has been explained. This arrangement will help students realize that English grammar functions by a set of rules that can be easily understood and mastered. Sentence diagraming is thoroughly practiced so that the student can see how the various parts of the sentence fit together. A convenient handbook in the back of the book makes it easy to look up anything the student may have forgotten. Periodic quizzes allow the student to determine if he has truly mastered the concepts taught.
