May half term Maths: Angles on a compass

​Clockwise

​Anti-Clockwise

​90

​180

​270

​When using a compass, we have to
remember how a circle has 360 degrees.

When we start with our fourmain points -
each point represents a 90 degree turn
(we can go either clockwise or anticlockwise

​Clockwise

​Anti-Clockwise

​90

​180

​270

If we started at North and turned clockwise 90 degrees, what direction would we be facing?

Challenge: If we turned 90 degrees anticlockwise, what direction would we be facing now?

​Clockwise

​Anti-Clockwise

​90

​180

​270

If we started at south, and we turned 180 degrees clockwise, what dirction would we be facing?


Challenge: What if we turned 270 degrees clockwise?

​0/360

If we started at north and turned 45 degrees clockwise, what direction do you think we would call this?
(halfway between north and east)

​0/360

​Clockwise

​Anti-Clockwise

​90

​180

​270

Halfway between each direction we have the diagonals, which are respectively north-east, south-east, south-west and north-west

These mark the 45 degree intervals between the main directions

​0/360

How many degrees is it between North East and East?

Challenge: How many degrees between north east and south?

​Clockwise

​Anti-Clockwise

Let's add in the final extra directions on our compass!

Key

NNE = north north east (halfway between north and northeast)

Can you work out what SSW and WNW mean?
They can be a little tricky to begin with!

​Clockwise

​Anti-Clockwise

These extra directions of NNE and ENE etc are half the distance between North and North East

45 divided by 2 = 22.5 degrees!

So each of these directions forms a 22.5 degree angle.

​Clockwise

​Anti-Clockwise

Stephanie faces north.

She has a fair coin which she tosses.

If the coin lands on Heads (H), she turns 45° clockwise.

If it lands on Tails (T) , she turns 45° anticlockwise.

Stephanie throws Tails once.

In which direction is she now facing ?
