Which activity is part of the Green Stroke School curriculum?

The correct activity that is part of the Green Stroke School curriculum involves performing the breaststroke arm action with support. This aspect of the curriculum is crucial as it introduces swimmers to the specific mechanics of the breaststroke, helping them to develop proper technique in a manageable way. By providing support, instructors can ensure that students focus on perfecting their arm movements without the fear of losing balance or coordination. This foundational skill is essential as it lays the groundwork for mastering the breaststroke later on.

In the context of swim education, it's important to engage students gradually. Activities like assisted forward movement, kick and pull, while beneficial in teaching swimming basics, do not specifically target the unique stroke technique that the Green Stroke School emphasizes. Similarly, the activities of swimming in trains or submerging underwater focus on other aspects of swimming and water safety rather than the specific components of the breaststroke.
