Success Criteria - By your next lesson 1. To be able to explain what a bearing is and why we use

them.2. 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

isto 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.

Bearings – The Key Points

1)Bearings are a measure of direction taken from North.2)Bearings are always measured in a clockwise direction3)Bearings are always written in 3 figures.

• Clockwise from the plane to Prince Edward Island I have measured the angle and it is 115°

• Bearing =115°

• Angle is marked on the diagram and is 245°
