6.PAR.8Coordinate Plane Graphing

Expectations

• 6.PAR.8.1

  Locate and position rational numbers on a horizontal or vertical number line; find and position pairs of integers and other rational numbers on a coordinate plane.

• 6.PAR.8.2

  Show and explain that signs of numbers in ordered pairs indicate locations in quadrants of the coordinate plane and determine how two ordered pairs may differ based only on the signs.

• 6.PAR.8.3

  Solve problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same x-coordinate or the same y-coordinate.

• 6.PAR.8.4

  Draw polygons in the coordinate plane given coordinates for the vertices; use coordinates to find the length of a side joining points with the same x-coordinate or the same y-coordinate.

What mastery looks like

Georgia's Achievement Level Descriptors. The levels are cumulative: each includes the ones before it. Proficient is on grade level.

Beginning

Plot an integer on a horizontal or vertical number line. Given a coordinate plane, identify the coordinates of a plotted point.

Developing

Plot a rational number on a horizontal or vertical number line. Identify the quadrant of an ordered pair. Solve problems by graphing points in the coordinate plane. Draw polygons in the coordinate plane when given the coordinates for the vertices.

Proficient

Plot an ordered pair made up of rational numbers in the coordinate plane. Explain that when two ordered pairs differ only by signs, the locations of the points are reflections across one or both axes. Solve problems by finding the distance between points with the same x-coordinate or the same y-coordinate. Determine the side lengths of polygons in the coordinate plane where two ordered pairs have the same x-coordinate or y-coordinate.

Distinguished

Solve relevant problems involving points in the coordinate plane by drawing polygons in the coordinate plane and determining distances between points that have the same x-coordinate or y-coordinate.
