Compare, order, and locate signed integers and rational numbers on a number line.
Order signed values in context
Problem
\(\text{Four}~\text{cities}\) reported these morning temperatures: Fairview, \(-6^{\circ}\text{C}\); Lakeport, \(3^{\circ}\text{C}\); Pine Ridge, \(-1^{\circ}\text{C}\); and Mesa Town, \(5^{\circ}\text{C}\). Order the cities from coldest to warmest.
Big Picture
What this problem is really about
Translate the context first: coldest to warmest means least to greatest temperature. Order the signed temperatures on a number line, remembering that the more negative temperature lies farther left and that all negative values come before the positives. Only after the numerical order is secure should you replace each temperature with its city name.
