A sixth-grade teacher wants to improve students' writing and decides to focus on developing their ability to use a wider variety of sentence patterns. Which of the following approaches will best meet the teacher's instructional goal?

While demonstrating proper comma usage is important for clarity in writing, it does not fundamentally address the variety of sentence structures. This approach focuses more on punctuation rather than expanding sentence patterns, which is the key goal of the teacher's instruction.

Although providing examples can be beneficial, simply demonstrating common patterns does not actively engage students in creating their own varied sentence structures. This method lacks the interactive element needed to develop students' skills in constructing diverse sentences.

Analyzing grammatical differences can enhance understanding, but it primarily focuses on identification rather than application. This approach might deepen students’ knowledge of sentence types but falls short of actively teaching them how to incorporate these varied structures into their writing.
