6.NS.C.6

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.

Identify the position of integers on number lines. Have examples of both horizontal and vertical number lines. Number lines may have a spacing other than one. For example:

$$\ldots, -10, -5, 0, 5, 10, ...$$
