Good Morning Year 4! Today, we are

moving onto our final Maths topic for Year

4 called ‘position and direction’. Our

target is ‘to describe position on a 2D

grid as coordinates’.

Don’t forget to write the date (24.06.20)

and the target, neatly at the top of your

page, using a ruler to underline it!

Target: To describe positions on a 2D grid as coordinates.

So, Miss Ingham, what exactly is a

coordinate and what does this have to do

with position and direction?

Great question! A coordinate is basically just a set

of numbers that tells us where something is on a

grid. We usually use coordinates for things such as

maps because it makes it easy and simple for us to

see where different places are located!

Target: To describe positions on a 2D grid as coordinates.

Here is an example of a basic

treasure map. On top of the treasure

map is a grid (set of lines going up

and down). This helps to break up the

map into smaller sections (boxes) to

help us easily locate different places.

Across the top and bottom are a

series of numbers!

Target: To describe positions on a 2D grid as coordinates.

These are some of the key things to

look out for when using coordinate

maps! Read the points carefully!

1) This is line is called the

‘y axis’. As you can see,

the numbers go up from 0

to 6. This helps us to find

points along that line! For

example, we can see that

the octopus and shark are

on line 1.

2) This is line is called the ‘x

axis’. As you can see, the

numbers go across from 0 to

6. This helps us to find points

along that line! For example,

we can see that the windmill

and postbox are on line 6.

3) The grid lines help us to

split up the map into smaller,

more manageable section!

Target: To describe positions on a 2D grid as coordinates.

So the question remains, how do you use those

numbers across the top and bottom to find

different points on the map? Read the points (in

numerical order) below to find out.

2) After you’ve found the

location of the point going

across the horizontal line,

now you must go across

the vertical line to find

that point as well. For

example the boat is on line

5.

1) You must always start

on the horizontal line!! For

example, if you are finding

the location of the boat,

you can see that it is in

line 8.

3) Now that you’ve found

the location of the point

on the horizontal and

vertical axes. All you need

to do is write these two

numbers as shown below:

(8,5).

Target: To describe positions on a 2D grid as coordinates.The important things to remember

when writing your coordinates are:

• Always go along the horizontal

line first!

• Always go along the vertical line

next!

• Write the two numbers, in the

same order mentioned above,

placing a comma in between!

Examples:

Elephant – (7,5)

Octopus - (1,1)

Lighthouse – (8,2)

Brick wall – (4,2)

Questions

Target: To describe positions on a 2D grid as coordinates.

Question 1: a) Which place is on the right-hand side of the shop?

b) Which place is next to the bank and close to the park?

c) The front gates of the school have been marked with a

cross. Write the coordinate of this point.

d) The slide in the park has been marked with a red cross.

Write the coordinates of this point.

Remember to go across the

bottom line first, then along

the vertical line next!

Target: To describe positions on a 2D grid as coordinates.

Question 2: a) Which point is at the bottom right

hand side of the grid?

b) Which two points are to the left

of point C on the map?

c) Write out the letters A-E in your

books and then find the

coordinates for each of these

points.

Question 3:a) Who do you agree with? Explain the reason for your

choice.

b) Write out the coordinates of the other shapes.

Target: To describe positions on a 2D grid as coordinates.

Question 4:a) Write out the letters A – F in your books and find the

location of each of the different points.

b) Teddy and Alex have chosen a point each!

Using the information shown in the speech bubbles,

which points could they have chosen?

Your task for today and tomorrow!

Target: To describe positions on a 2D grid as coordinates.

Your task for today and tomorrow is to create your own treasure map! You can start

this today and finish it off tomorrow. We will also be writing instructions tomorrow

as well! If you have a printer available, you could print off the grid lines to make it

easier for you. Alternatively, using a ruler, neatly draw out a grid on some paper!

Target: To describe positions on a 2D grid as coordinates.

Your treasure map must include:

• A title telling us the name of the place!

• A horizontal line with numbers (or letters),

going across.

• A vertical line with numbers going up.

• A red line to show how you will reach your

treasure from the starting point.

• An X to mark the point where your

treasure is located!

• Colour to make the design eye-catching

and interesting!

• Obstacles along the way (e.g. a dense

forest, pirates, lava, etc.)
