As single paragraphs expand into essays, students are ready for more complex writing pieces. With a friendly tone, the Rev Up Your Writing series explains how different genres express ideas. Each book focuses on a specific genre, describing its purpose, how it's structured, and its unique traits. Original writings, illustrations, photos, and easy-to-follow writing tips add to the appeal of the series. Additional features to aid comprehension include a table of contents, a phonetic glossary, informative sidebars, sources for further research, an index, and an introduction to the author and illustrator.
