Coordinates are ordered pairs of numbers; the first number number indicates the point on the x axis and the second the point on the y axis. When reading or plotting coordinates you always go across first and then up a good way to remember this is: 'across the landing and up the stairs'.

They may then be given a blank grid and asked to plot the following coordinates : 1, 1 4, 1 1, 3 and 4, 3 then join up the points to make a shape which in this case would be a rectangle. In Year 6, children learn to draw, locate and complete shapes that meet given properties.
For example: The square's coordinates are 3, 3 , 5, 2 , 6, 4 and 4, 5. They may also be asked to reflect , rotate or translate a shape on a coordinates grid and then give the coordinates of the new shape they have drawn.
In Year 5 or 6, a child might be given a shape that has some coordinates marked on, but where the coordinates grid is not marked. Ordered pairs are written in parentheses x -coordinate, y -coordinate. The origin is located at 0,0. Note that coordinates are often written with no space after the comma. The location of 2,5 is shown on the coordinate grid below. The x -coordinate is 2. The y -coordinate is 5. To locate 2,5 , move 2 units to the right on the x -axis and 5 units up on the y -axis.
The order in which you write x - and y -coordinates in an ordered pair is very important. The x -coordinate always comes first, followed by the y -coordinate.
As you can see in the coordinate grid below, the ordered pairs 3,4 and 4,3 are two different points! The function table below shows the x - and y -coordinates for five ordered pairs. You can describe the relationship between the x - and y -coordinates for each of these ordered pairs with this rule: the x -coordinate plus two equals the y -coordinate. In fact, the graph forms a straight line. The arrows indicate that the line goes on in both directions.
Your students may have encountered ordered pairs last year, but it's a good idea to start by reviewing how to locate a point on a grid from an ordered pair. A day spent plotting coordinates that fall in a straight line will be a day well spent. Materials: Poster paper or a way to display a coordinate grid publicly for the class; straightedge.
Preparation: Draw a large coordinate grid that the entire class can see. Label the x - and y -axes from 0 through Prerequisite Skills and Concepts: Students should know about ordered pairs and locating points on a grid. At this level, students will begin to see the relationship between equations and straight-line graphs on a coordinate grid. Key Standard: Interpret an equation as a linear function, whose graph is a straight line. Materials: Poster paper or a way to display a coordinate grid publicly for the class; straightedge; one copy of a coordinate grid, a straightedge, and lined paper for each student.
Preparation: Draw a coordinate grid where all students can see it. Ensure all students have a copy of the grid. They should also be able to recognize and interpret an equation. Wrap-Up and Assessment Hints These skills will need lots of practice. Reinforce the need for students to work carefully so their graph is accurate. When you assess students' progress, keep the number of exercises small enough that they have time to complete each step without rushing.

Drawing a Coordinate Graph The numbers on a coordinate grid are used to locate points. In this diagram, R is an equal distance from P and Q.
What are the coordinates of R? Answer: 50, This diagram shows two identical rectangles on coordinate axes. Write the coordinates of point A and point B. Here is a kite. Write the coordinates of point D. A counter is placed on square D4. It is moved 2 squares right and 3 squares down. Write the position of the square it lands on. Answer: F2.
