Correct Response: D. Any dance activity should be preceded by a warm-up session to prepare students' bodies for movement and help reduce the risk of injury. A warm-up increases heart rate, body temperature, and blood flow to muscles and connective tissues, which become more flexible and less likely to tear. Discussing individual students' challenges (A), demonstrating and practicing difficult steps (B), and reviewing a video of a previous practice session (C) are all useful activities for student learning, but can be incorporated into lessons at other, often more appropriate, times. These strategies are not as important to student safety as is warming up before the folk dance activity.
