Aim:
Understand how bearings can be used to describe relative directions and journeys.
How you'll know that you've been learning today:
Can measure bearings with a protractor, and use them with changes-of-scale to calculate distances traveled in journeys.

Copy the names from the features, and write down the 3 digit bearing from the center to the different objects.

Outdoor Bearings Activity:
- Orient towards North, and draw a ‘North’ line
- In pairs, accurately chalk a large (1m²) compass rose of N,S,E,W,NE,SE,SW,NW. Then also draw large squares, triangles. Challenge: draw a 6-pointed star
- Work out bearings FROM any <start> TO any <finish>
- Give instructions in your pairs to navigate all the way to a destination. First by only using the compass directions. Then more complicated using exact bearings.
- Extension: use trundle wheels to follow/give instructions about directions AND distances. e.g. 5m N, 5m E, 5m S, 5m W should land back on the same spot.
- Precision Challenge: Starting from the NE corner, travelling 5m W, 2m S, 3m NE, 1M SSE, point to a dot and write your name next to it.

You started by reading and interpreting bearings.
Now you need to write and explain using bearings.
And if we have a scaled map, we can measure it (and do scale-drawing calculations) to calculate real-life distances!

·# Identifying and Writing Bearings ·## Starter: ·pg60 Ex.4 Q3to5 when finished, draw a sketch of a Compass into jotter with labels and 3 digit bearings for N, NNE, NE, ENE, E etc. · ·## Assess: ·Question 4 is more tricky. If you aren’t sure how to do it; try it, raise your hand to tell me, and then move on to Question 5. · ·## Demonstrate: ·### Algebra for Question 4. ·360° = 50° + 310° ·360° = 50° + 180° + 130° · ·50° is that bearing measured counter-clockwise (which is incorrect) ·310° is the same bearing, but measured clockwise (which is correct) · ·This is to prevent us from getting our directions mixed up. · ·# Measuring angles and converting them into bearings ·## Complete pg62 Ex.5 Q1to4 ·Be careful when the angle is larger than 180° · ·## Worksheet: Labeling Bearings ·Start and end points are given, you need to construct the ‘North’ lines, then follow the arrow to measure bearing FROM the start TO the end. Apply cardinal direction labels (when appropriate) for N,S,E,W,NE,SE,SW,NW Bonus: Do the same thing but FROM the end TO the start. · ·# Outdoor Bearings Activity ·1.
