•Point Fred at the place you want to go, or the direction you want to find.

•Turn the dial until the RED north arrow is in the shed in the middle of the dial.

•Find the white line under Fred. Read the compass “bearing” where the dial and the white line meet.

Bearing

• Give the students the following bearing.

180o

• Have the students then “Put Red in the Shed” (have them turn their bodies, NOT the compass)

• Tell them if they walked that direction (Follow Fred), they would be walking 180o from North (which would be South.)

• Ask them what bearing 90o would be.• Ask them what bearing 270o would be.
