The Coordinate Plane(part 1)

OBJECTIVE:

Each student will:• Graph points on a coordinate plane.• Name the quadrants of a coordinate

plane.• Find and position pairs of integers and

other rational numbers on a coordinate plane

Connector:

KEY VOCABULARY Coordinate plane- The plane containing the "x" axis and "y" axis.

Cartesian Coordinates- Using Cartesian Coordinates you mark a point on a graph by how far along and how far up it is. Quadrants- The four sections of a coordinate grid that are separated by the axes.

“y-axis”

“x-axis”

Coordinates- (x, y)

Quadrants

Two Points in Quadrant I

Two Points in Quadrant II

Two Points in Quadrant III

Two Points in Quadrant IV

(2,5) a(5,2) b(1,3) c(4,0) d(0,2) e(4,5) f(2,1) g(-1,3) h(3,-4) i(-4,-2) j(-2,0) k

QUESTIONS:

1. What do you notice about the coordinates of all points in quadrant I?

2. What do you notice about the coordinates of all points in quadrant II?

3. What do you notice about the coordinates of all points in quadrant III?

4. What do you notice about the coordinates of all points in quadrant IV?
