Learning ObjectivesPupils will be taught to...| Teaching and Learning Activities| Learning OutcomesPupils will be able to ...| Remarks| 1 Understand the concept of bearing.| Introduce the eight main compass directions.| Draw and label the eight main compass directions: a) north, south, east, west, b) north-east, north-west, south-east, south west.| Vocabulary north-eastsouth-eastnorth-westsouth-westcompass anglebearing| 2 Use the concept of bearing.| 1 Show and calculate the compass angle of any direction.Examples :State the bearing of point P.Answer : 48˚Answer : 180˚ + 60˚ = 240˚Answer : 180˚ - 40˚ = 140˚ Answer : 270˚ + 20˚ = 290˚Answer : The bearing of A from B is 065º. The bearing of B from A is 245º.2 Discuss the use of bearing in real life situations. For example, in map reading and navigation. Example : In Diagram 8, P, Q and R are three points on a horizontal plane. R lies to the east of P. The bearing of Q from P is 072˚.The bearing of R from Q is A 162˚B 198˚ C 288˚D 342˚| 1 State the compass angle of any compass direction.2 Draw a diagram which shows the direction of B to A given the bearing of B from A.3 State the bearing of point A from point B based on the given information.4 Solve problems involving bearings.| Point to noteCompass angle and bearing are written in three-digit form, from 000˚ to 360˚. They are measured in a clockwise direction from north.Due north is considered as bearing 000˚.For cases involvingdegrees and minutes, state in degrees up to one decimal place.|
