The x-axis runs horizontally (left-right) through zero.

The y-axis runs vertically (up-down) through zero.

The origin is where the x-axis and y-axis cross. It has the coordinate pair (0,0).

Write coordinates for already marked points in the first quadrant of a coordinate grid

Maths

In this unit pupils will give directions from one position to another on a grid and move objects including polygons on a grid according to directions, and mark the new position. They will describe and draw polygons specified by translations. In the future unit pupils will describe positions in all four quadrants drawing and translating simple shapes and reflecting them in the axes.

In the prior unit pupils rotated two lines around a fixed point to make different sized angles. They identified vertices. In this unit pupils will give directions from one position to another on a grid and move objects including polygons on a grid according to directions, and mark the new position. They will describe and draw polygons specified by translations.

Coordinates

Question: To find a coordinate, we must count along the _________ first. 

Look at the grid below.
Which is the correct coordinate for the point marked by the dot?

Look at the grid below.
Which is the correct coordinate for the point marked by the star?

Look at the grid below. Write down the coordinates for the plotted point. Remember to use brackets and a comma.

Sofia challenges Jacob to spell out her word shown by the image. Which coordinates will spell this word? 

Sofia says: ‘If a point is located at (5, 2) on a grid, the number 5 represents the x-coordinate and 2 represents the y-coordinate.’ Is this true or false? 

What is the coordinate of the dot on the grid?

What is the coordinate of the star on the grid? 

Sofia and Jacob are playing a game of Alien Treasure. Jacob says ‘My treasure is at the coordinate (5, 3).’ 

This lesson will soon be taken down.
