Designed to encourage students to discover that grammar merely represents the patterns that exist in language, this book presents lessons on 19 grammar points: nouns; pronouns; verbs; subjects; capitalization; end punctuation; commas; sentence fragments; run-on sentences; contractions; possessives; quotation marks; adjectives; adverbs; prepositions; interjections; conjunctions; compounds; and subject and verb agreement. Each lesson begins with examples, definitions, and directed questions, followed by exercises that rely on both traditional and nontraditional approaches. For example, students may be asked to follow sentence patterns, write their own sentences, choose effective modifiers, or combine sentences. Comprehensive exercises for parts of speech, sentences, punctuation, and errors are included at the end of the book, and can be used to supplement, diagnose, or evaluate students. (MM)
