-	{{lesson slide\|\|}}	+	{{lesson slide\|00:42\|5 min}}
		+	'''Pacing'''

		+	* We measure distance by counting our paces
		+	* One pace is the same foot landing again - i.e. two steps
		+	* Every search worker should know how many of their personal paces there are in 10 meters
		+	* ''measure out 10m on level open ground''
		+	* ''demonstrate measuring your pace''
		+	** ''if start with LEFT foot, count every time your RIGHT foot lands. Or vice versa''
		+	* ''have each student measure their pace. So many paces to 10m. E.g. 5.5 paces for 10m''

-	3/ Pacing	+	* ''distribute Pacing and Traverse - If You Dare worksheet''
		+	* ''have each student work out their paces in 50m and 100m; the distance they travel in 30 paces, 50 paces.''

-	* ~~Step is one foot~~ to ~~the opposite~~	+	* If not clear ground, you may have to step around things like logs or trees.
-	* ~~Pace is one foot to the same foot (two steps)~~	+	** count only your paces when you think they make up a full pace

-	* ~~counting your pace~~	+	* Similarly going up or down a slope, our paces are slightly shorter or longer

-	* measure your pace in 10m	+	{{lesson slide\|00:47\|13 min}}
		+	'''Exercise'''

-	* ~~calculating distance~~ from ~~paces~~	+	* Exercise sheet lists 3 traverses
		+	* Everyone should start from a different point in the open field
		+	* Not to close to fences on slope
		+	* Mark your starting point on the ground
		+	* You should end up where you started
		+	* ''Have each student work through (alone) Traverse #1 from the exercise sheet'''
		+	* ''As time permits have them carry on to Traverse #2 or #3''
		+	* ''Ideally, students should end up within a pace of their starting point''
		+	* This exercise can help you get more accurate with your pacing and bearings
		+	* You can take the worksheet and practice it at home to further improve

-	* calculating paces from distance	+	{{lesson slide\|01:00\|}}
		+	'''Advanced extras'''

-	~~4/ Exercises: bearings~~	+	''If time permits, or as arises with student questions''

-	* ~~hand-out: Pacing~~ and ~~Traverse~~	+	'''Back bearings'''
-		+	* You can shoot back from your destination to your starting point
-	~~5/ Advance~~	+	* The difference between a bearing and a back bearing should be exactly 180 degrees
-		+	* Use a back bearing to check your measurements
-	~~As they come up in discussion, describe:~~	+	* Or use it if there is no object to sight on (e.g. field of snow) and you can leave a marker (e.g. flagging tape) where you started from
-		+
-	* back ~~bearings~~	+
-		+
-	* ~~offsets~~	+

		+	''Offset''
		+	* Sometimes you can't walk the bearing you want. E.g. across a slew
		+	* Take a side bearing 90 degrees different from your original bearing (left or right)
		+	* Count your pace until you're away from the obstacle
		+	* Take your original bearing past the obstacle
		+	* Reverse your side bearing (180 different) the same number of paces
		+	* Your back to your original line and can continue on your original bearing
