So now, if you had to describe the location of the point (red dot) of this plane to another person, how would describe it?

Adding grid and number lines makes it easier to describe the location of the point! Now, let's identify some Coordinate Plane Vocabulary.

Take a look at the coordinate plane in the image below. Make observations, then based on the image, see if you can define the vocabulary words that follow.

Also known as the Cartesian Coordinate Plane, the grid and number lines form the_______ PLANE:

A Origin

B Coordinate

C Axis

D Quadrant

The point where the two axes intersect (or cross) is called the:

A Origin

B Coordinate

C Axis

D Quadrant

The coordinate plane is divided into 4 areas. These areas are called:

A coordinates

B number lines

C quadrants

D grids

What direction do the quadrants move?

A right to left

B down to up

C left to right

Based on what you have learned so far, let's practice. Give the coordinates of the points and the location of each quadrant in the image below.
