A complete and comprehensive grammar program! Lessons on topics such as sentence fragments or parts of speech begin with several pithy examples, and follow them with directed questions that help students arrive at a grammatical principle or rule. Following the questions and a brief discussion, each lesson has a Definition, set in a box for emphasis. Lessons also contain boxed Hints that aid students in understanding and retaining points of grammar. Each book also contains a Comprehensive Exercises section that provides review exercises and includes errors for students to correct. Book 1 is appropriate for grades 5-6 and covers parts of speech, basic punctuation and capitalization, sentence fragments, run-on sentences, contractions, possessives, and subject and verb agreement.
