In 6th grade, students are expected to have a good understanding of signed numbers, so that they can easily identify the opposite of a given number and plot them on a number line. Teachers can use “Identify opposites on a number line Quiz” to identify areas where students may need additional support to understand the opposite numbers. To solve this quiz, they should remember that on a number line, the opposite numbers are the same distance from 0, but on the other side. For example, if the given number is 2 then its opposite number is -2, and if the given number is -5 then its opposite number is 5.
