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 understanding comma usage is important for clarity in writing, this approach does not primarily focus on varying sentence patterns. It addresses punctuation rather than the construction or variety of sentence structures themselves, which is essential for achieving the teacher's instructional goal.

Although providing examples can aid students in recognizing different sentence structures, it may not actively engage them in using these patterns in their writing. This approach lacks the interactive element necessary for students to practice and apply varied sentence structures effectively.

Analysis of grammatical differences can enhance students' understanding of sentence types, but it does not necessarily equip them with the skills to implement these structures in their writing. The focus is more on identification rather than application, which is less effective for developing a varied sentence style.
