What are positions in the first quadrant?

A coordinate grid is made up of four quadrants. Here we will focus on the first quadrant. A quadrant is a 2d grid. We need to know about the horizontal x axis, and the vertical y axis, which intersect at the origin. We need to know about these axes to mark and read coordinates in the first quadrant.

First we read the x coordinate, then we read the y coordinate. We can use the rhyme, ‘Along the corridor and up or down the stairs’.

For each location here, first we need to identify the location on the map. Then, read along the x axis and write this down, next read up the y axis and write down the number the location is lined up with.

How do we write coordinates?

Finally, we write the coordinates as a pair within brackets, separated by a comma to show they are for separate axes. For example, if we read along to 7 and up to 3, we would write (7, 3).

More practise

For more practise on reading and writing coordinates in the first quadrant, take a look at the worksheets on this website.

• Which of these images shows the first quadrant?

Hints

The x axis always goes across and the y axis goes up and down. Check that these axes have been labelled correctly.

The first quadrant is made up of two lines. These look a bit like an 'L' shape.

The numbers go up in steps of 1, starting from zero.

Solution

This is the correct image of the first quadrant.

The x axis goes across from left to right, the y axis goes up and down and these meet at 0.

The intervals go up in positive numbers from 0 for the first quadrant.

• Where is each item?

Hints

To find the coordinates of each item, first read along the horizontal x axis.

Then read up the vertical y axis.

Here we can see the star is at (6,8). First we read across to 6, then we read up to 8.

Solution

The coordinates for each item are shown in the image.

Hints

Remember to first read along the x axis.

Second, read up the y axis.

Here, a cross has been marked at (6,2). That is because we go across 6 and up 2.

Solution

The coordinates that should be highlighted in the colours are shown in the image.

• (2,7) is green.
• (5,8) is yellow.
• (1,3) is pink.

• What is the location of each letter?

Hints

Begin by locating the letter on the map. Then, read along the x axis to find the first coordinate in the pair.

Second, read up the y axis to see what the letter is in line with. This is the second coordinate in the pair.

Solution
• a = (2,5)
• b = (4,2)
• c = (4,5)
• d = (6,3)
• What is the image at (3,4)?

Hints

First, read along the x axis until you reach 3.

Next, read up the y axis until you reach 4.

Solution

The icon at (3,4) is the tree.

• What are the coordinates of each letter?

Hints

The first coordinate is the number on the x axis.

The second coordinate is the number on the y axis.

Make sure to write each coordinate either side of the comma.

Solution
• a = (1,2)
• b = (2,4)
• c = (4,2)
• d = (0,5)
