Lesson 7.37.3 Small Group · Group 1
Start hereWords, worked example, and sentence starters
Learning target With my small group, I can find the absolute value of a rational number — an integer, fraction, or decimal — as its distance from zero — one step at a time, with support.
Why This Matters This is your support small group for Lesson 7.3. We're going to slow this down and build it together, one step at a time. You can ask a question any time — that's what this group is for.
Start hereWords for this lesson
Read each word before you begin. Say it out loud.
| Word | What it means | Example |
|---|---|---|
| IntegerSpanish: Número entero | Whole numbers and their opposites, like -2, -1, 0, 1, 2. | ... -3, -2, -1, 0, 1, 2, 3 ... shown on a number line with 0 in the center |
| PositiveSpanish: Positivo | A number bigger than zero, to the right of zero on a number line. | +5 means 5 above zero, like 5 floors above ground level |
| NegativeSpanish: Negativo | A number smaller than zero, to the left of zero on a number line. | -3 means 3 below zero, like 3 floors underground |
| Absolute valueSpanish: Valor absoluto | How far a number is from zero. It is never negative. | |−3| = 3 and |3| = 3 |
| OppositeSpanish: Opuesto | Two numbers the same distance from zero, on opposite sides, like 3 and -3. | −3 and 3 are opposites |
| Rational numberSpanish: Número racional | A number that can be written as a fraction of two integers, with a bottom number that is not zero. | −3/4, 0.5, 7, −50 |
How it worksWorked example
These numbers are not on your problems. The steps are. Follow them with your own numbers.
Find |−13| and |6|. Which number is farther from 0?
- −13 is 13 units left of 0, so |−13| = 13.
- 6 is 6 units right of 0, so |6| = 6.
- Compare the distances: 13 > 6.
Answer: −13 is farther from 0
Now you trySame steps, your turn
The steps are the same as the worked example. The numbers are yours. Do the work.
Find |3|, the absolute value of 3.
Say it and write itSentence starters
Finish each sentence out loud with a partner. Then use them in your writing.
- The absolute value of is because it sits units from zero.
- and share the same absolute value because .
- An absolute value is never negative because .
- The number closer to zero is because its distance is .

Watch out!A common mistake
A common mistake in Integers and Absolute Value is judging size by the digits alone instead of position on the number line

1Complete each step, then write the final answer.
Count from −8 to 0. Find |−8|, the absolute value of −8.
- 1Is −8 to the left or right of 0?
- 2Count the units from −8 to 0. How many?
- 3So what is |−8|?
Final answer: -
2Complete each step, then write the final answer.
This time the number is a decimal. Find |−3.5|, the absolute value of −3.5.
- 1Where is −3.5 on the number line?
- 2How many units is −3.5 from 0?
- 3Can a distance be negative?
Final answer: -
3Complete each step, then write the final answer.
Find |−11|.
Show your workHint How many units is −11 from 0?
Final answer: -
4Complete each step, then write the final answer.
Find |−3/4|.
Show your workHint −3/4 is between −1 and 0. How far is it from 0?
Final answer: -
5Complete each step, then write the final answer.
A town is at an elevation of −20 feet. Sea level is 0. How far is the town from sea level?
Show your workHint Distance from sea level is the absolute value of the elevation.
Final answer: -
6Complete each step, then write the final answer.
Ben says |−5| = −5. Is he right? What is |−5|?
Show your workHint Absolute value is a distance. Can a distance be negative?
Final answer:
Explain your thinkingBen wrote |−5| = −5. Explain his mistake. Why is an absolute value never negative?
Sentence starter An absolute value is never negative because ___. · |−5| = ___ because −5 is ___ units from 0.
