Learning target I can show I am caught up on Lessons 7.1–7.3 by using each lesson's big idea in mixed practice.
Start hereWords for this lesson
Read each word before you begin. Say it out loud.
| Word | What it means | Example |
|---|---|---|
| IntegerSpanish: Número entero | The counting numbers, their opposites, and 0. | ..., -3, -2, -1, 0, 1, 2, 3, ... |
| OppositeSpanish: Opuesto | A number that is the same distance from 0 as another number, but on the other side of 0. | −3 and 3 are opposites |
| Negative numberSpanish: Número negativo | A number less than 0, written with a − sign. On a number line it sits to the left of 0. | -86 meters means 86 meters BELOW sea level |
| Positive numberSpanish: Número positivo | A number greater than 0. On a number line it sits to the right of 0. | 9°C is 9 degrees ABOVE zero |
| Number lineSpanish: Recta numérica | A straight line where numbers are placed in order. It extends to the left of 0 to show values less than 0. | -3, -2, -1, 0, 1, 2, 3 marked in order from left to right |
| Rational Numbers on the Number LineSpanish: Números racionales en la recta numérica | Every rational number has one exact spot on the number line. Writing it as a fraction, a decimal, or an integer does not change where it sits. | −3/2 = −1.5 and 1/2 = 0.5 each sit at one exact point. |
How it worksWorked exampleusing absolute value to see which number is closer to 0
These numbers are not on your problems. The steps are. Follow them with your own numbers.
One freezer logged −23 degrees and another logged 17 degrees. Which reading sits closer to 0?
- Absolute value measures distance from 0, so the sign does not matter here.
- Distance from 0 for the first reading: −23 = 23
- Distance from 0 for the second reading: 17 = 17
- Compare the two distances; the shorter distance sits closer to 0.
Answer: |−23
Now you trySame steps, your turn
The steps are the same as the worked example. The numbers are yours. Do the work.
A fish swims at −31 meters and a gull flies at 28 meters. Which one is closer to the water surface at 0?
- Absolute value measures from 0, so the sign does not matter.
- Distance from 0 for the fish: −31 =
- Distance from 0 for the gull: 28 =
- Compare the distances; the distance is closer, so the is closer.
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 outA common mistake
A common mistake in Integers and Absolute Value is judging size by the digits alone instead of position on the number line — students think -8 is 'more' than -3 because 8 > 3, when really -8 sits farther left (colder, deeper, or lower) and is actually the SMALLER integer. Absolute value measures distance from zero and is always positive or zero, but that distance does not decide which integer is greater — only left-to-right order on the number line does. Before you submit, ask: am I comparing distance from zero (absolute value) or position on the number line (greater/less than)?

(Lesson 7.1) Badwater Basin is 86 meters below sea level, and sea level is 0. Which integer represents that elevation?
- A-86
- B-68
- C0
- D86
Hint Sea level is 0. Is 'below sea level' more than 0 or less than 0?

(Lesson 7.1) In Reykjavik the temperature was -9°C. What is the opposite of -9?
- A-18
- B-9
- C0
- D9
Hint 'Opposite' means the same distance from 0, but on the other side of 0.

(Lesson 7.3) What is the absolute value of -9?
- A-9
- B0
- C1
- D9
Hint Absolute value asks: how FAR is -9 from zero? It's about distance, not direction.
