The Editor in Chief® Level 1 book includes 12 easy-to-understand lessons in grammar and mechanics and 69 activity pages. The lessons include the following: content, capitalization, punctuation, spelling rules, nouns, pronouns, adjectives, adverbs, articles, verbs, agreement, conjunctions, prepositions, interjections, confusing word pairs, negative words, homophones, homographs, run-on sentences, and sentence fragments. After learning a lesson, students apply the rules by correcting the errors, and reviews provide more challenging practice of the multiple skills already taught. Detailed answers are also included.
