Strong language skills are essential to success in school and life. Knowing the elements of language and understanding how they work together greatly enhances all language-based abilities. Grammar Practice Simplified Book D is designed to help students use the parts of speech correctly in speaking and writing. Students review the kinds of sentences; then they study nouns, pronouns, and verbs and use these elements in sentences. Students are introduced to subjects and predicates, adverbs, and adjectives. Punctuation is covered in detail, including correct use of the period, question mark, exclamation point, comma, and apostrophe. Capitalization of sentences, proper nouns, and proper adjectives is reviewed. Some activities encourage students to write independently. Readability has been carefully controlled for younger students, but the approach and design make the book useful for older, language-delayed students or students who speak English as a second language. Answers are provided at the back of the book. Book D is Grades 5-6.
