At my high school, we use a grammar book as part of our English curriculum. Over the years, we've used three different books that all have chapters arranged the same: grammar first (parts of speech and sentences, phrases and clauses), usage second (verbs, pronouns, modifiers), then mechanics last (punctuation, capitalization, and spelling). In the past, each English teacher on our level has covered the chapters whenever they wanted to during the year. Some would start at the first chapter, and some would skip around. Now that we are trying to create common assessments, we have to work out a plan to cover the same chapters in the same semester. If you have a similar grammar book and are expected to teach the chapters, what order do you choose and why? Do you think certain topics should be taught before others? Your opinions are appreciated.
