Morse Code Whistle and Flag Relay
Teams send clues from one end of the field to the other using Morse code with a whistle or flag, the way hikers did before cell phones, and the decoded message tells them where the next task is. Students practice long-distance communication, focus, and distress signals.
How to play
- Intro (4 min): the teacher hands out a Morse code chart and explains dots and dashes with a whistle (short and long blasts) and with a flag (up and to the side). Teach the SOS distress signal.
- Teams of five split into senders (two) and receivers (three), standing 40 yards apart between two cones.
- The teacher gives the senders a card with a four-letter word that names a spot on the field, such as "GOAL."
- Senders transmit it letter by letter with pauses; receivers decode it with the chart and then run together to that spot, where a card with a number is waiting.
- They bring the number back to the teacher and switch roles; each team sends four messages (16 min) and scores a point per correct message.
- Wrap-up (5 min): the whole class quietly practices the distress signal with flags and discusses when it is used outdoors.
Rules
- Only senders use the whistle, and nobody blows it near anyone's ears.
- Receivers can't walk over to ask; if unsure, they raise an arm and the message is repeated.
- Run to the spot as a group and walk back.
Variations
Easier
Use three-letter words and allow a chart with pictures of the dots and dashes.
Standard
Four-letter words by whistle or flag over 40 yards.
Harder
Send short two-word phrases and have senders switch between whistle and flag without warning.
Adaptations
- Limited mobility: the student is a fixed sender with a flag and the team sends a receiver back with the answer.
- Hearing impairment: use only the flag and face the senders; visual impairment: use only the whistle.
- Skill level: faster students receive without the chart by memorizing the most common letters.
Learning goals
- Use a signal code to communicate over distance outdoors.
- Stay focused and accurate when sending and receiving messages.
- Know the distress signal and when it should be used.

Teacher tip
Space teams well apart so the whistles don't get mixed up; staggering starts helps a lot. If you're short on whistles, start with flags only.
