Wake up what you know, then explore today's model.
Activa lo que sabes y luego explora el modelo de hoy.
- Predict which is greater, −7 or −3. Put the first location at −7 and the second at −3, and read the steps from the first to the second. Then swap the two locations. Write your prediction, your test, and your evidence. Explain how the direction of the steps tells you which number is greater.

- Fill in the table
- Three cities have temperatures of −12°F, −5°F, and 3°F. Which city is warmest?
- −5°F
- −12°F
- 3°F
- They are equal
- Spot the Common Mistake
- What is the best next move?
- Say −14 is greater, because 14 is greater than 8.
- Say the one farther left is greater.
- Place both on a number line and pick the one farther right.
- Put 0 at the left end and measure each number from there.

- Which day was coldest?
- Thursday at −1°F
- Tuesday at 2°F
- Monday at −4°F
- Wednesday at −7°F
- Which is colder, −4°F or −1°F?
- −4°F, because it is farther left on the number line
- −1°F, because 1 is smaller than 4
- They are the same
- −1°F, because it is closer to zero
- Order the temperatures from coldest to warmest.
- −1, −4, −7, 2, 5
- 2, 5, −1, −4, −7
- 5, 2, −1, −4, −7
- −7, −4, −1, 2, 5
