Ordering Integers and Understanding Signs

This video tutorial covers the ordering of positive and negative integers using number lines. It explains how to graph integers on both horizontal and vertical number lines, emphasizing the importance of paying attention to the signs of the numbers. The tutorial also includes a practical example of graphing temperature data from a table and ordering the temperatures from least to greatest and vice versa. The lesson concludes with a preview of the next topic, which will focus on writing inequalities.

What is the correct order of the integers -1, 0, 2, and 3 from least to greatest?

• 0, -1, 3, 2

• -1, 0, 2, 3

• 3, 2, 0, -1

• 2, 3, -1, 0

When graphing integers, why is it important to pay attention to the signs in front of the numbers?

• Because they determine the color of the number

• Because they indicate whether the number is positive or negative

• Because they show the size of the number

• Because they tell you how many times to graph the number

On a horizontal number line, what happens to the value of numbers as you move to the right?

• The numbers become negative

• The numbers decrease in value

• The numbers stay the same

• The numbers increase in value

How do numbers change in value on a vertical number line as you move upwards?

• They increase in value

• They become negative

• They stay the same

• They decrease in value

Which city has the lowest average low temperature based on the given data?

• City D with 0°F

• City A with -8°F

• City C with -15°F

• City B with 12°F

What is the correct order of the cities' temperatures from least to greatest?

• 12, 7, 0, -2, -5, -8, -15

• 7, 12, 0, -2, -5, -8, -15

• 0, -2, -5, -8, -15, 7, 12

• -15, -8, -5, -2, 0, 7, 12

If the order from least to greatest is -15, -8, -5, -2, 0, 7, 12, what is the order from greatest to least?

• 12, 7, 0, -2, -5, -8, -15

• -15, -8, -5, -2, 0, 7, 12

• 0, -2, -5, -8, -15, 7, 12

• 7, 12, 0, -2, -5, -8, -15

What is the next topic to be covered in the lesson series?

• Graphing more complex numbers

• Writing inequalities

• Understanding fractions

• Solving equations
