A basic grammar workbook loaded with lively and interesting exercises that allow students to put their own ideas and energy into a process of learning by activity rather than by passive absorption.Let's Communicate was written to meet the need for a basic book for elementary and middle school students that would present fundamentals of grammar in a thorough and challenging way, yet enable students to put their own ideas and energy into it. The book contains many practice exercises that help the student learn each skill by actually using it. Skills mastered early in the book are reviewed and constantly used in later exercises. Learning by activity, not passive absorption, is the goal. The parts of speech are studied separately to show how they help build ideas into sentences. This early section of the book is followed by the chapters on mechanical skills. These chapters are presented in order of difficulty or logic (for example, students frequently confuse plurals and possessives, so these two chapters are presented in sequence).

The last three chapters, Outlines, Letters, and E-mails are not grammatical in nature, but are helpful, and students find them interesting. The final page of each chapter is titled "Check Your Understanding" and may be used as a test.
