Step 1
Absolute value is distance
Absolute value tells how far a number is from zero. It does not tell direction.
๐ |-12| = 12 and |12| = 12

Grade 6 ยท Maths ยท Lesson 2.2
Use absolute value to compare distance from zero and inequalities to compare signed numbers.

Helping with: Absolute Value and Integer Inequalities
MATH-G6-N02 ยท The Subterranean Compass
Teacher Welcome
I am your Subterranean Compass math teacher. I will help you use signed numbers, absolute value, and coordinate grids like a navigator.
Teacher Response
Is the situation above zero or below zero?
Ask for a Specific Hint
Teacher Tip
Always label the direction first: above, below, left, right, up, or down. Then decide whether the number should be positive or negative.
Common Mistake Alert
Remember: absolute value is distance from zero. Distance cannot be negative.
Student Question Box
Helper Suggestion
Type a question above. The helper will guide the student toward the first step without giving away the answer immediately.
Challenge Prompt
Can you create your own coordinate grid problem using a drone, robot, or underground tunnel?
Warm-Up
Which is farther from zero: -8 or +5? How do you know?
-8 is farther from zero because |-8| = 8 and |+5| = 5.
Vocabulary
Integer
A whole number, zero, or the opposite of a whole number, such as -3, 0, or 7.
Opposite numbers
Numbers that are the same distance from zero but on opposite sides of the number line.
Absolute value
The distance a number is from zero on the number line.
Coordinate plane
A two-dimensional grid formed by the x-axis and y-axis.
Quadrant
One of the four regions created by the x-axis and y-axis.
Real-World Connection
Absolute value is used to measure distance from sea level, temperature change, account balance distance from zero, and grid distance.
Mini Lesson
Step 1
Absolute value tells how far a number is from zero. It does not tell direction.
๐ |-12| = 12 and |12| = 12
Step 2
A location can be negative, but the distance from zero is always zero or positive.
๐ Distance scanner removes direction.
Step 3
-4 is greater than -18 because -4 is closer to zero on the number line.
๐ -18 < -4

Activity 1 ยท scenario-challenge
A polar bear hunts at -5 meters relative to sea level. A deep-sea crab crawls at -25 meters. Write an inequality comparing their depths, and determine who is deeper.
๐ก Use the visual model first. Then write the signed integer, inequality, coordinate, or distance.
Absolute Value and Inequalities
A polar bear is at -5 meters. A deep-sea crab is at -25 meters.
Interactive Visual Model
[Sea Level 0] โ Bear (-5) โ Crab (-25) โ -5 > -25
Activity 2 ยท scenario-challenge
Diver A is at -40 feet. Diver B is at -15 feet. Use absolute value to calculate who is a greater physical distance away from the surface boat at 0 feet.
๐ก Use the visual model first. Then write the signed integer, inequality, coordinate, or distance.
Absolute Value and Inequalities
Diver A is at -40 feet and Diver B is at -15 feet.
Interactive Visual Model
|-40| = 40 feet away | |-15| = 15 feet away

Activity 4 ยท scenario-challenge
A weather drone flies at +80 meters. A submarine dives at -80 meters. Use absolute value to show if one vehicle is further from sea level than the other.
๐ก Use the visual model first. Then write the signed integer, inequality, coordinate, or distance.
Absolute Value and Inequalities
A drone is at +80 meters and a submarine is at -80 meters.
Interactive Visual Model
