The Semaphore Flag Tactical Coastal Signal Relay

45 mins Ages 9-14 Outdoor

An engaging, screen-free learning activity that builds real-world creativity and critical thinking for kids aged 9 to 14.

Materials Needed

  • • Bright bandanas or square fabric flags (red and yellow) (4 units)
  • • Wooden craft dowels (approx. 50 cm long) (4 units)
  • • Printed maritime semaphore reference charts (2 sheets)
  • • Compact binoculars (optional) (1 unit)

Pro Tips

  • → Tie red or yellow bandanas to two wooden dowels to make official maritime signal flags.
  • → Each letter corresponds to an exact clock-face angle formed by your two arms (e.g., A = 8 o'clock and 6 o'clock).
  • → Station teams 50 meters apart across an open park, using binoculars to decode secret transmissions.

Safety First

Maintain visual contact across open fields; do not run into park obstacles while signaling.
