Analyze, Organize, Write [PDF ebook] 

This book offers students a method for understanding and mastering the rhetorical patterns that comprise expository writing. Its exercises ask students to arrange jumbled sentences into logical order, forming model essays for standard rhetorical patterns such as comparison/contrast, classification, and thesis support. These techniques force students to see the basic logic of different writing patterns. The goal of Whimbey’s workbook is to teach the student to write concise and original essays on any topic.
