Check understanding
- Define absolute value as distance from zero on a number line
- Calculate the absolute value of positive and negative rational numbers
- Distinguish between comparing absolute values and comparing signed numbers in real-world contexts
“Can your child tell you that the absolute value of −7 is 7 — because it's 7 steps from zero on a number line regardless of direction — and use this idea to compare distances?”
