Coordinate Graphs and Graphing Lesson Kirstine Barber
Andrew Lewis Middle School
Salem City Schools, Salem, VA
VA SOL: 7.12, 8.16
Lesson Plan:
- Warm-Up: Learn Check on the calculator on integers, absolute value and integer
vocabulary. (Send the students the Learn Check through TI-Navigator. Use as a
warm-up for coordinate graphing).
- Notes on Coordinate Graphs and how to locate and graph points. (Coordinate
Graphing student notes).
- Activity: Using the Activity Center, have students plot ordered pairs. Cut up the
ordered pairs sheet so that each student has one set of four ordered pairs. Have
them each plot the first ordered pair, then the second, etc. Students will be able
to watch themselves graph the points on the computer (you will need a projector
that is hooked up to your computer so that students can watch their progress).
o After they graph the first ordered pair, have them look at the points that are
graphed. Every point should be in the first quadrant. Ask the students to
look at the ordered pair they graphed and discuss what they noticed about
their ordered pair. The students should conclude that when the x
coordinate and the y coordinate are both positive, the ordered pair is
plotted in the first quadrant. Continue with the other three ordered pairs.
o Have students check each other’s progress throughout lesson.
o After using the Activity Center, check what the students know by asking
the following Quick Poll questions. (Make sure to cover the lens if using a
projector so that students cannot see how others are voting).
- Yes/No: Is (2, 2) in quadrant III?
- Yes/No: Is (0, 3) on the x-axis?
- Yes/No: Is (0, 0) in the first quadrant?
- Make up your own Quick Poll questions.
- Self-Check: Learn Check on coordinate graphing. Students will need to identify
where certain points are located.

Vocabulary:
- Coordinate plane: The plane formed by two perpendicular
lines called the x-axis and y-axis.
- The coordinate plane is divided into four regions. Each region
is called a quadrant.
x-axis
origin
y-axis
- x-axis: the horizontal number line.
- y-axis: the vertical number line.
- Ordered pair: a pair of numbers that represents a unique point
in the coordinate plane. The first value is the x coordinate and
the second value is the y coordinate.
o Ex. 1: (2, 3) → 2 is the x coordinate and 3 is the y
coordinate
- Origin: the center of the coordinate plane. It has coordinates
(0, 0). It is the point where we always start when we are
graphing.
To graph a point in the coordinate plane start at the origin. Look
first at the x coordinate. If the x coordinate is positive, move that
many spaces to the right. If the x coordinate is negative, move
that many spaces to the left. From your x coordinate location
look at the y coordinate. If the y coordinate is positive, go up that
many spaces. If the y coordinate is negative, go down that many
spaces.
On the coordinate plane below, graph A (0, 2), B (4, -3), C
(-2, -1), D (2, 3), E (2, 0) and F (-5, 3).
List the quadrant that each point is in:
