Lesson details

Key learning points

  1. The position of a point can be described in terms of another point.
  2. When translating, you described moving left/right and up/down.
  3. For bearings, you describe standing on a point and turning a number of degrees to face the new point.
  4. The bearing is always measured clockwise from North and described with three digits.
  5. The distance to the new point does not need to be described, but can be.

Keywords

  • Bearing - A bearing is an angle measured in degrees from North in the clockwise direction and written with three figures.

Common misconception

Neglecting to follow the 3 conventions of bearings. Particularly, going anticlockwise when given a bearing over 180 degrees.

Pupils can be asked to stand and turn 90 degrees. Some will turn clockwise and some anticlockwise. This will create a discussion point about the direction being important. Having the clockwise convention means a direction does not need to be given.

Pupils that are not confident with using a protractor can be provided with more opportunities to practice the conventions of bearings using isometric paper. This will take away the need to use a protractor and concentrate on the basics of bearings until they are confident enough to move on.
