Step-by-Step Guided Lesson
Step 1: Start Video
(Tips: Interact with the video by pausing, to ask questions or discuss information viewed with student.)
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.
1. -5 + 5
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

2. -15 ÷ 5
3. -15 ÷ -5
4. 6/-2
5. -9/-3
6. 5/-5
7. -8 ÷ -8
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.
