The teacher’s note and concise layout reduce the time required to cross‑reference student work with the answer key, enabling faster grading or in‑class checks.

Overall, page 34 strikes a balanced middle ground: it offers more instructional scaffolding than a bare answer key while staying succinct enough for quick classroom use. Rating: ★★★★☆ (4 out of 5 stars)
