Title

Graphing Integers On A Coordinate Plane

Lesson Objective

The student will plot ordered pairs on a coordinate plane and identify the coordinates for a point on a coordinate plane. A

minimum of two students are needed for this lesson's activity.

Background Information for Teacher

Materials:

● Starter problems (Step 2)

● Map with coordinates

● A large X you cut out or print on a paper

● Graphing calculators

● Journal page (Step 3)

Step 2: Teach Lesson

Tell the student, today we will be learning how to plot ordered pairs on a coordinate plane.

Have the student number their paper with four columns as shown. Show the student one column at a time and give each

column as a 1-minute timing. The student will write answers only.

2. 6 + 3

3. 7 + -5

4. -2 + -2

5. -8 + 9

6. 10 + 5

7. -4 + -5

8. 4 + -8

9. -3 + 3

10. -8 + -8

1. -5 – 5

2. 6 – (- 3)

3. 7 – 5

4. -2 – 2

5. -8 – (-9)

6. 10 – -5

1. 3 x 5

2. -3 x 5

3. -3 x -5

4. 6 • -2

5. -9 • -2

6. 5 • -5

7. -8 x -3

8. -4 x 5

9. -1 x -1

10. 7 • -3

1. 15 ÷ 5

8. -4 ÷ 4

9. -1 ÷ -1

10. 12/-3

Tell the student, now we are going to see when coordinate systems are used in real life.

Show the student a map and ask the student to locate a city given coordinates from the map. Allow the student time to

locate.

Discuss the need for ordered pairs or coordinates, for a coordinate system, and for an origin.

Divide into one or two teams and explain the game:

Each team should pick a “Seeker” and a “Guide”.

The Seeker will be blindfolded. The Seeker will stand in an open area of the room walking as directed by the Guide, who

will give directions in the form of, “Take ___ steps to your right (or left, forward, backward). The rest of the team will

suggest to their Guide (in whispers) what directions to give their Seeker. The Seeker faces the front of the room at all

times, never turning, and may only move right, left, forward, or backward. The team will be timed on how long it takes to

get their Seeker to the Target (a large X).

Begin by blindfolding the Seeker from one team, and facing the Seeker towards the front of the room. Remind the seek

they may not turn at all. Place a large X on a diagonal from the Seeker. The team gives suggestions to the Guider as to

what to say to the Seeker until the Seeker reaches the X.

When the team begins, a timer should be started. (If there are more than one team when the Seeker has reached the

target, the other team will have a turn).

The team who takes the least time getting the Seeker to the target, wins.

Discuss need for ordered pairs or coordinates

, for a coordinate system

, and for an origin

.

Show the student a coordinate plane

. Tell the student, If an invisible coordinate plane could be placed on the Earth,

we could easily identify specific locations and travel to those locations. Longitude and Latitude lines are similar

to a coordinate plane, except that they are laid on a sphere rather than a plane.

Tell the student, now we are going to learn how ordered pairs can be represented symbolically and graphically

Show the student how to write coordinates (similar to the directions they gave in the game) for a given location or point.

Have the student complete their journal page (Step 3), and place a point at that location.

Explain that we always give directions in a certain order (thus, ordered pairs). Just like going to your room in a hotel. You

must first walk across the floor or the hall before getting into the elevator.

Have the student plot a point on the graphing calculator. The student should plot a point and identify the coordinates for

that point.

Have the student complete the Single Line Graph worksheet for extra practice.
