Math 5.8

Geometry and measurement. The student applies mathematical process standards to identify locations on a coordinate plane. The student is expected to:

  • (1) 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;
    • (A) describe the process for graphing ordered pairs of numbers in the first quadrant of the coordinate plane; and
    • (B) graph in the first quadrant of the coordinate plane ordered pairs of numbers arising from mathematical and real-world problems, including those generated by number patterns or found in an input-output table.
