Learn about absolute value
Content is AI-assisted and continuously improved through educator review
Learning Objective
Students will be able to explore learn about absolute value.
In this lesson, we'll explore learn about absolute value. Mathematical thinking develops logical reasoning and problem-solving abilities.
Absolute value is the distance a number is from zero on the number line, without caring about direction. We write it with bars: |x|. The absolute value is always positive or zero. For example, |5| = 5 and |-5| = 5 (both are 5 units from zero). Absolute value tells you "how far" without telling you "which way." It's useful for finding distances, temperatures differences, and solving equations!
As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.
Take notes on key points and make connections to what you've already learned in previous lessons.

Teaching Tip
For this age group: Balance direct instruction with collaborative activities. Allow students to explain their thinking and make connections to prior knowledge when exploring learn about absolute value.
