Lesson details
Key learning points
- The position of a point can be described in terms of another point.
- When translating, you described moving left/right and up/down.
- For bearings, you describe standing on a point and turning a number of degrees to face the new point.
- The bearing is always measured clockwise from North and described with three digits.
- 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.
