What is this lesson plan about?


This is a short 1-hour practical training on taking and following bearing with a compass and pacing distance, to be done outside in an open area.

A small student to instructor ratio (max 5:1) is recommended. As such, this lesson is often one station of several with a larger class broken up into smaller teams of max 5 students and this session is taught repeatedly by the same instructor as the teams move between stations. See "Search skills and compass practical" as a commonly used example of this lesson as one of several stations.

instructional points in normal font

aids, exercises, activities in italic

1/ discuss Magnetic Declination

  • Where needle points
  • Reading declination from map (add grid N)
  • Adjusting declination on compass

2/ shooting a bearing with a compass

  • using compass
    • avoid metal
      • belt buckle
    • avoid magnetic fields
  • holding compass
    • hold flat
  • sighting
    • using mirror
    • using sighting notches
  • reading bearing
    • rotating barrel
    • "red to the bed"
    • parallax problem
      • parallel needle edge, not needle in the middle
    • practice reading bearings to several objects
    • vary distance and note differences in error
  • walking a bearing
    • setting bearing
    • how far to look
    • practice finding destinations at several bearings

3/ Pacing

  • Step is one foot to the opposite
  • Pace is one foot to the same foot (two steps)
  • counting your pace
  • measure your pace in 10m
  • calculating distance from paces
  • calculating paces from distance

4/ Exercises: bearings

  • hand-out: Pacing and Traverse
