Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates. Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes. Find and position integers and other rational numbers on a horizontal or vertical number line diagram; find and position pairs of integers and other rational numbers on a coordinate plane.

Find the value of a number using its distance and direction from zero
In this lesson you will learn how to find the value of a number by comparing its distance and direction from 0.

Find opposite numbers on the number line
In this lesson you will learn how to find opposite numbers by comparing their distances and directions from 0.

Locate a point on the coordinate plane
In this lesson you will learn how to locate a point on a coordinate plane by plotting an ordered pair.

Determine the quadrant of a point
In this lesson you will learn how to determine the quadrant of a point by examining the values of an ordered pair.

Predict the reflection of a point by changing values
In this lesson you will learn how to predict the reflection of a point by changing one or more of its values in an ordered pair.
