0606.3.9 Graph ordered pairs of integers in all four quadrants of the Cartesian coordinate system.

I CAN graph ordered pairs in ALL four quadrants!!!

Have you ever had to give directions or follow someone else's direction to get to a specific destination?

We use a coordinate system on earth to find exact locations. The equator is like the x-axis, and the prime meridian is like the y-axis.

The lines that run east-west are lines of latitude. They are measured in degrees north and south of the equator.

The lines that run north-south are lines of longitude. They are measured in degrees east and west of the prime meridian.

x-axis

y-axis

origin

Vocabulary coordinate plane - is formed by two number

lines in a plane that intersect at right angles. The point of intersection is the zero on each number line.

x-axis - horizontal axis y-axis - vertical axis Quadrants - the two axes divide the

coordinate plane into four sections Origin - the point where the axes intersect Coordinates - the numbers in an ordered

pair

y-axis

x-axisOrigin(0, 0)

Quadrant II(-, +)

Quadrant I(+, +)

Quadrant IV(+, -)

Quadrant III(-, -)

Have you ever used a ladder?

First you have to move the ladder towards what

you want to clime

Second, you climb up

Or used an elevator?First you have to go over

and into the elevator

Then you go up or down

A (-2, 3)

B (1, 2)

C (0, -2)

D (-2, -3)

1. Which location in Texas is closest to the ordered pair (5, 2)?Galveston

2. Which location in Texas is closest to the ordered pair (6, 1)? El Paso

3. What ordered pair best describes the location of Dallas, Texas? (3, 2)

4. Which place in Texas is located in Quadrant III of this coordinate plane? Big Bend National Park

Texas

Graph the following coordinates.

1. A (-4, 3)2. B (-8, 3)3. C (-8, 0)4. D (-4, 0)5. E (-4, -3)6. F (-8, -3)7. G (2, 3)8. H (-2, 3)9. I (-2, -3)10. J (2, -3)11. K (4, -3)12. L (4, 3)13. M (6, 0)14. N (8, 3)15. O (8, -3)

My Example

GRAPH PROJECT PROCEDURESSPI 0606.3.9 I can graph ordered pairs of integers in all four quadrants.

Rough draft of your picture. Rough draft picture approved by the teacher. After teacher approval put dots/points where they belong and

label them for capital letters. Write your letters on the side of the paper in order, including

stops. Write the ordered pair and the matching letter. 2nd sheet of graph paper - plot your points and connect. List ordered pairs (coordinates) on a separate piece of paper. This

will be exchanged with other students. On Monday you will turn in rough draft, final picture, and ordered

pairs (coordinates).

Closure

Turn to your shoulder partner and explain how the graphing project meets the objective for today!!!!
