Numbers on a number line
Understand the absolute value of a rational number as its distance from zero on the number line; interpret absolute value as magnitude in real-world contexts; distinguish absolute value comparisons from ordering statements
Suggested ages 11–12
Evidence of 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
Assessment prompt
Can Numbers on a number line 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?
