## Standard Alignments:

(A) Describe the key attributes of the coordinate plane, including perpendicular number lines (axes) where the intersection (origin) of the two lines coincides with zero on each number line and the given point (0, 0); the x-coordinate, the first number in an ordered pair, indicates movement parallel to the x-axis starting at the origin; and the y-coordinate, the second number, indicates movement parallel to the y-axis starting at the origin

5.8.B(B) Describe the process for graphing ordered pairs of numbers in the first quadrant of the coordinate plane

(Y5) Use a grid reference system to describe locations. Describe routes using landmarks and directional language (ACMMG113)

ACMMG143(Y6) Introduce the Cartesian coordinate system using all four quadrants (ACMMG143)

ACMNA178(Y7) Given coordinates, plot points on the Cartesian plane, and find coordinates for a given point (ACMNA178)
