Key idea

Numbers increase left to right, always. Negatives are a mirror of the positives: −3 sits as far left of 0 as 3 sits right of it. On a grid, (x, y) means across first, then up/down.

Sample problems

Which is farther left: −6 or −2?
Between which two whole numbers does −½ lie?
Between which two whole numbers does 2.5 lie?
Write −7/2 as a decimal, then name the two whole numbers it lies between.

Common mistakes to watch for

Chose −1 by comparing the digits 3 and 1 instead of the positions.
Placed it between 0 and 1 (ignored the sign) or at −1 exactly.
Said Quadrant IV — reversed the coordinates and plotted (3, −4) instead.

The answer key explains each one, so you can tell what a wrong answer means.
