The 33 activities in this book reinforce the rules of written English by providing students with practice in editing a variety of formats. The activities help students develop a basic understanding of the rules of grammar and mechanics (generally taught in grades 6-7) in context and exercise their critical thinking abilities by identifying content errors in a writing sample and accompanying illustration and caption. Each activity contains 1-4 content errors (a discrepancy between the illustration/caption and the writing sample) and 6-12 errors in spelling, mechanics, and grammar. The book presents suggestions for using the activities, an editing checklist to aid in the editing task and a scope and sequence guide that gives teachers an overview of the types of errors include in each writing sample. The answer key lists corrections for each activity. A guide to grammar, usage, and punctuation that cover the skills used in the book is attached. (RS)
