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:

Estimating Angles The Competition!!

The Rules of the game!:

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

Bearings – The Key Points:

Bearings – The Key Points Bearings are a measure of direction taken from North . Bearings are always measured in a clockwise direction Bearings are always written in 3 figures. from North . clockwise 3 figures

Example 1: What is the compass direction from Belfast to Omagh? …………………… What is the bearing from Belfast to Omagh? ……………………:

Example 1: What is the compass direction from Belfast to Omagh ? …………………… What is the bearing from Belfast to Omagh ? …………………… North Omagh Belfast from Belfast West 270 °

Example 2: What is the rough compass direction from Omag to Newry? …………………… What is the bearing from Omagh to Newry? ……………………:

Example 2: What is the rough compass direction from Omag to Newry? …………………… What is the bearing from Omagh to Newry? …………………… North Omagh Newry from Omagh South East 125 °

Example 3: What is the rough compass direction from Omag h to Sligo? …………………… What is the bearing from Omagh to Sligo? ……………………:
