Third-Grade Inclusive Relay and Asthma Safety
Ms. Brooks teaches third-grade physical education to 28 students in a gym with one bench and limited space. The lesson is a continuous relay: students run 30 meters, do five push-ups, and return. She wants moderate-to-vigorous physical activity for at least 50% of class. During the first round, six students are breathing hard and sprinting, four are standing in line, one student with asthma reports tightness and uses an inhaler, and two students with low fitness are walking slowly and look embarrassed. The class has 30 minutes. Ms. Brooks has cones, beanbags, jump ropes, and a heart-rate chart but no monitors. The school wellness policy emphasizes inclusive participation and fitness knowledge.
1. Modify the relay so it is safer and more inclusive while still aiming for moderate-to-vigorous physical activity for at least half the class. Explain the trade-offs in your design.

A better design is a station-based circuit with three or four small groups and no elimination. For example: Station 1, cone shuttle walk-jog with a beanbag; Station 2, jump-rope or imaginary jump-rope for a set time; Station 3, step-ups on a low bench with one foot at a time; Station 4, beanbag toss and retrieve. Students rotate every 90 seconds and choose a 'steady' or 'challenge' version of each station. The teacher uses a whistle to signal rotation, so no one stands in a long line. The student with asthma should have a modified station and quick access to the inhaler; the two students with low fitness can choose the steady version without being singled out.
The trade-off is that a circuit requires more transitions and equipment setup, and some students may choose too easy a version. Ms. Brooks can keep the whole class moving during transitions with a 10-second 'move to the next cone' countdown and can prompt students to increase effort during the last 20 seconds of each station. The goal of 50% MVPA is more likely with small groups and active transitions than with a single relay line. Push-ups should be optional or replaced with wall push-ups because five push-ups can cause form breakdown and embarrassment.
2. Ms. Brooks has no heart-rate monitors. How can she monitor intensity, respond to the asthma symptoms, and decide whether students are working at a moderate-to-vigorous level?

She can use the talk test and perceived exertion. Moderate activity allows a student to talk but not sing; vigorous activity makes talking difficult. She can teach a simple 1-to-5 effort scale: 1 is sitting, 3 is walking briskly, 4 is breathing hard but controlled, 5 is sprinting. Students touch the number on a posted chart during transitions. She should also scan for warning signs: wheezing, coughing, tightness, pale or flushed face, unusual fatigue, or a student stopping abruptly. For the student with asthma, she should follow the health plan, stop activity, help the student use the inhaler, and notify the school nurse or parent as required. The student should not be forced to 'push through' tightness.
To decide about MVPA, she can sample the class every five minutes: count how many students are moving with purpose versus standing. If more than half are standing, she changes the transition or station. She can also use a step-count estimate or a simple check: 'Can you talk while you move?' This is not as precise as heart-rate monitoring, but it is practical and teaches students to self-monitor. The asthma student's safety takes priority over the MVPA target.
3. What fitness concept should Ms. Brooks teach in the last five minutes, and how can she assess it without a written test?

She should teach the difference between intensity and duration, using the talk test and the effort scale. Students can explain why a brisk walk can be moderate activity for one student but vigorous for another, and why the asthma student may need a different pace. She can also introduce the idea that fitness includes cardiorespiratory endurance, muscular strength, flexibility, and body composition, but the day's focus is endurance and pacing.
Assessment can be a 30-second partner check: one partner performs a steady movement for 20 seconds while the other asks, 'Could you talk? Could you sing? What number on the effort scale?' Then they switch. The teacher listens for students using the language 'breathing harder,' 'talk but not sing,' and 'steady pace.' She can collect a quick exit slip with two sentences: 'Today I worked at level ___ because ___. One way I can stay safe is ___.' This assesses fitness knowledge and self-monitoring without a formal written test and keeps the class active.
