Students develop real-life editing skills for superior writing and top test scores! Editor in Chief improves students' grammar, punctuation, spelling, capitalization, and attention to detail using a standards-based thinking approach rather than drill and practice. This effective method teaches students to carefully analyze and edit stories that contain errors in writing mechanics and story details. The stories combine single skills (like capitalization) with guided, gradual instruction and practice that is ideal for younger learners. Students identify and circle errors in each story. Then they insert, modify, or delete punctuation, words, and short phrases to make corrections. An editing checklist and annotated guide to grammar, usage, and punctuation are provided to help focus students' thinking and allow them to match their answers to applicable rules. Detailed answers are also included. Grades 6-8.
