What This Standard Means
What Students Need to Do
- Students locate integers and other rational numbers on horizontal and vertical number lines. They also plot ordered pairs of rational numbers on the coordinate plane.
What Mastery Looks Like
- The student places values such as -1.5 and 3/4 accurately between labeled benchmarks. The student plots (-2.5, 1) with the correct coordinate order and quadrant.
Common Misconceptions
- Students may place negative values farther right as their magnitude increases. They may reverse x and y coordinates or ignore a coordinate sign.
How to Assess It
- Ask students to plot -3/2 on a horizontal number line, 5/4 on a vertical line, and (-2, 3/2) on a coordinate plane.

Ways to Teach It
Place rational-number cards on floor number lines, then transfer ordered pairs to a large coordinate grid.
Ask students how each sign in an ordered pair determines movement from the origin.
Play Coordinate Callout by plotting rational pairs and naming their quadrant or axis.
Graph elevation and horizontal distance data for landmarks using rational coordinates.
