This unique and timely resource gives writing teachers over 250 ready-to-use activity sheets to correct 101 of the most frequent errors made by students in grades 4-12. For each error, it provides two or more reproducible activities based on the writing process to help students understand and correct that problem. These can be completed independently with minimal teacher supervision and include solution keys for self-correction and evaluation. To assure easy use, materials are printed in a big 8-1/4 x 11 lay-flat binding that opens flat for photocopying. The book is organized into eight sections, including Word Usage Help, Punctuation Help, Spelling Help, Grammar Help, Sentence Writing Help, Paragraph Help, Essay Writing Help, and Letter Writing Help.
