Which of the following strategies is most appropriate for a teacher to use to help develop pre-K students' cardiovascular endurance?

While lead-up games can be beneficial in developing skills and preparing students for more extensive activities, they may not provide the sustained cardiovascular exertion necessary for enhancing endurance. These games often focus on skill acquisition rather than continuous movement.

Stretching, whether dynamic or static, primarily focuses on flexibility and muscle readiness rather than cardiovascular endurance. While essential for injury prevention and preparation, stretching alone does not significantly contribute to enhancing endurance levels in young children.

Timing students in jump rope activities may encourage individual performance and competition, but it does not inherently promote cardiovascular endurance. The focus on timing could detract from the enjoyment of movement, which is crucial for maintaining engagement in pre-K students.
