Comparing and Ordering Integers

This video lesson, part of lesson 4.3, focuses on comparing and ordering integers. It begins with an introduction and preparation of notes. The lesson explains how to compare integers with different signs, emphasizing that positive integers are always greater than negative ones. It then covers comparing integers with the same sign using a number line, illustrating how to determine which is greater. Finally, the lesson teaches how to order integers from least to greatest and greatest to least, using examples and a number line for clarity.

• Above zero.

• To the right of zero.

• To the left of zero.

Which is greater: -2 or -4?

• Cannot be determined.

• -2

• -4

• They are equal.

On a vertical number line, where are negative integers located?

• Above zero.

• Below zero.

• To the right of zero.

• To the left of zero.

Which is greater: 3 or 1 on a vertical number line?

• Cannot be determined.

How would you order the integers -8, -1, 0, 3, 6 from least to greatest?

• 0, -1, -8, 3, 6

• 6, 3, 0, -1, -8

• -8, -1, 0, 3, 6

• 3, 6, 0, -1, -8

How would you order the integers 6, 3, 0, -1, -8 from greatest to least?

• -8, -1, 0, 3, 6

• 3, 6, 0, -1, -8

When ordering integers, what should you pay close attention to?

• Whether the integers are positive or negative.

• The digits of the integers.

• The position of zero.

• The order being asked: least to greatest or greatest to least.
