Unlike traditional grammar books that emphasize the parsing of sentences, this worktext asks students to imitate the sentence styles of professional writers, making the sentence composition process an enjoyable and challenging one. Killgallon teaches subliminally, nontechnically—the ways real writers compose their sentences, the ways students subsequently intuit within their own writing.

Designed to produce sentence maturity and variety, the worktext offers extensive practice in four sentence-manipulating techniques: sentence unscrambling, sentence imitating, sentence combining, and sentence expanding. All of the activities are based on model sentences written by widely respected authors. They are designed to teach students structures they should but seldom use. The rationale is that imitation and practice are as valuable in gaining competence and confidence in written language production as they are in oral language production.

Since the practices have proven successful for the great majority of students who have used them in all kinds of schools, it's demonstrably true that Sentence Composing can work anywhere—in any school, with any student.
