In the worksheets, are grammar concepts continually reviewed throughout the year? Or do you teach a concept, have worksheets, and then move on to the next topic?
The answer to your question is both!
Mr. Stephens teaches grammar in isolation and students complete the activities before moving on to other activities. Later in the year, when he teaches students composition such as paragraphs, etc., Mr. Stephens constantly refers to grammar (and other important content covered earlier in the year) during the drafting and revision process.
Grammar activities in levels that have been updated to second edition are divided into “identify” and “apply” activities. The goal is to isolate the parts of speech and allow students to not only identify them in sentences, but learn how to use the parts of speech as tools for effective communication. The “application” of such is revisited again during the drafting and revising stages of all compositions.
