if you're teaching math to students who are ready to learn about absolute value, typically around Grade 6, here's an overview of the topic, along with two lessons to introduce and develop the concept with your students.
alue of a number is never negative.
The absolute value of –5 is 5. The distance from –5 to 0 is 5 units.

The absolute value of 2 + (–7) is 5. When representing the sum on a number line, the resulting point is 5 units from zero.

The absolute value of 0 is 0. (This is why we don't say that the absolute value of a number is positive. Ze

The most common way to represent the absolute value of a number or expression is to surround it with the absolute value symbol: two vertical straight lines.

|6| = 6 means “the absolute value of 6 is 6.”

|–6| = 6 means “the absolute value of –6 is 6.”

|–2 – x| means “the absolute value of the expression –2 minus x.”

–|x| means “the negative of the absolute value of x.”

The number line is not just a way to show distance from zero; it's also a useful way to graph equalities and inequalities that contain expressions with absolute value.

Consider the equation |x| = 2. To show x on the number line, you need to show every number whose absolute value is 2. There are exactly two places where that happens: at 2 and at –2:
