Ask several other questions in which students identify numbers that are some set distance away from a given number. Draw a number line like the one shown below, with some of the numbers missing. Draw several other number lines that use a scale other than one. Ask students what some of the missing values are on the number lines you have drawn. Using a scale other than one is often needed when graphing numbers which vary greatly in size.
All negative numbers are to the right of zero on the number line.
