This writing conventions lesson focuses on using subordination to indicate relationships between ideas. The lesson includes research-based strategies and strategic questions that prepare students for assessments. In this lesson, students determine the relationship of two sentences and then the best conjunction to indicate that relationship. Then, they combine the clauses to form a complex sentence, varying between dependent first and independent clause first. Finally, they label the clauses. In addition to the lesson, there are eight pages of Independent Practice and review modeled on current adaptive testing methods.
