**Bearings**Learning Intentions To understand what a bearing is To be able to work out and measure bearings Success Criteria - By your next lesson To be able to explain what a bearing is and why we use them. To be able to say what the 3 key points are.**Estimating Angles**The Competition!! Starter**The Rules of the game!**An angle will appear on the screen, your job is to estimate the size of the angle. The winner is the person who gets the most points. • All angles are a multiple of 5. • If you guess the angle exactly right give yourself 3 points. • If you are 5° out give yourself 2 point. • If you are 10° out give yourself 1 point. • You will have 30 seconds to guess – then the answer will come up. Hint**Estimate the Angle**10° - 1 point 15° - 2 points 20° - 3 points 25° - 2 points 30° - 1 point THE POINTS**Estimate the Angle**140° - 1 point 145° - 2 points 150° - 3 points 155° - 2 points 160° - 1 point THE POINTS**Estimate the Angle**125° - 1 point 130° - 2 points 135° - 3 points 140° - 2 points 145° - 1 point THE POINTS**Estimate the Angle**60° - 1 point 65° - 2 points 70° - 3 points 75° - 2 points 80° - 1 point THE POINTS**Estimate the Angle**90° - 1 point 95° - 2 points 100° - 3 points 105° - 2 points 110° - 1 point THE POINTS**BEARINGS**WHAT’S THE POINT?**Compass points**360° 000° N 045° 315° NW NE E 270° W 090° SW SE 225° 135° S 180°**Bearings – The Key Points**Bearings are a measure of direction taken from North.
