Build the idea

Mark zero and equally spaced whole-number ticks. Partition each interval into equal parts for the denominator. Negative values are left of zero on a horizontal line and below zero on a vertical line.

WORKED EXAMPLE 1

Draw a horizontal or vertical number line. Plot and label -5, 0, and 2.

-5 < 0 < 2; unit steps

Negative -5 is left of or below 0; 2 is right of or above 0. Use equal intervals.

WORKED EXAMPLE 2

Draw a horizontal or vertical number line. Plot and label -7/3, 0, and 2/3. Name the step size of your scale and explain the placement.

-7/3 < 0 < 2/3; use steps of 1/3

Negative -7/3 is left of or below 0; 2/3 is right of or above 0. Use equal intervals.
