This resource focuses on teaching students the importance of responding immediately and safely to a whistle signal in physical education settings. It outlines the steps students should take when they hear the whistle: stopping movement, holding equipment still, looking at the teacher, and listening for further instructions. Additionally, it includes the 'Safe Gym Rules Checklist', where students can affirm their understanding of safety protocols by coloring circles next to the rules. The document also incorporates a 'Freeze Drill Practice' exercise, where students can practice freezing upon hearing the whistle during active movement in the gym. There is a creative section for students to illustrate or write about what they will freeze to demonstrate their listening skills.
