Why are -5 and 5 both the same distance from zero on the number line, even though one is negative and one is positive?
Check for Understanding #1
Teacher: If >30% thumbs down, re-teach with a fresh example before moving on.
Treasure Map Elevation
Captain Vega's treasure map has clues hidden at different elevations! Some treasures are buried underground (below sea level) and some are on mountaintops (above sea level). Sea level is marked as 0. A treasure chest is at -4 (4 meters below sea level) and a lookout tower is at +6 (6 meters above sea level). How far is each from sea level?
Concept Launch
💡 What is absolute value?
An integer is a whole number that can be positive, negative, or zero. The absolute value of a number is how far it is from zero on the number line. Distance is never negative.
Absolute value tells you the distance from zero, so it is always positive or zero.

| Term / Término | Meaning / Significado | Example / Ejemplo | Visual |
|---|---|---|---|
| Integer Número entero |
A whole number that can be positive, negative, or zero. Un número entero que puede ser positivo, negativo o cero. |

| Positive Positivo |
A number bigger than zero, to the right of zero on a number line. Un número mayor que cero, a la derecha del cero en la recta numérica. |
+5 means 5 above zero, like 5 floors above ground level | |
| Negative Negativo |
A number smaller than zero, to the left of zero on a number line. Un número menor que cero, a la izquierda del cero en la recta numérica. |
-3 means 3 below zero, like 3 floors underground | |
| Absolute value Valor absoluto |
How far a number is from zero. It is never negative. Qué tan lejos está un número de cero. Nunca es negativo. |
|-5| = 5 and |5| = 5 — both are 5 units from 0 | |
| Opposite Opuesto |
Two numbers the same distance from zero, on opposite sides, like 3 and -3. Dos números a la misma distancia de cero, en lados opuestos, como 3 y -3. |
3 and -3 are opposites — both are 3 units from 0 |

🎯 Listen For · Common Errors
• Student says both are 5 units from zero (same absolute value) but are opposites because of their signs.
• Student uses absolute value to show both are 30 feet from sea level (zero), ignoring direction.
• Student explains the opposite flips the sign while absolute value always gives the non-negative distance from zero.
• Student gives a real context (temperature, elevation, money) and explains zero as the reference point between positive and negative.
Common mistake: A common mistake in Integers and Absolute Value is skipping the key idea: "Absolute value tells you the distance from zero, so it is always positive or zero." — always check your work against this rule before you submit.
Answer Key (Teacher Appendix)
Hide this slide during presentation or move to the end of your copy.
✓ Practice 1: |-4| = |4| because both are 4 units from zero — Absolute value measures distance from zero. Both -4 and 4 are 4 units from zero, so |-4| = |4| = 4.
✓ Practice 2: 9 — Absolute value is the distance from zero. -9 is 9 units from zero, so |-9| = 9.
✓ Practice 3: 7 — |-3| = 3, |7| = 7, |-5| = 5, |2| = 2. The greatest absolute value is 7.
✓ Practice 4: 0 — Zero is 0 units from itself on the number line, so |0| = 0.
✓ Exit ticket: -8 — To the left of zero means negative. The integer -8 has an absolute value of 8 because it is 8 units from zero.
