Comparing Numbers on Number Lines

The video tutorial for grade 6 students covers the topic of comparing and ordering integers. It explains how to use both horizontal and vertical number lines to compare integers, emphasizing that positive integers are greater than zero and negative integers are less than zero. The tutorial provides examples to illustrate these concepts and guides students on how to order integers from least to greatest using a number line.

What is true about positive integers on a horizontal number line?

• They are always less than negative integers.

• They are equal to zero.

• They are always greater than zero.

• They are always less than zero.

If you compare -1 and 2 on a horizontal number line, which statement is correct?

• -1 is greater than 2.

• -1 is equal to 2.

• -1 is less than 2.

• -1 and 2 cannot be compared.

On a vertical number line, how do positive integers compare to zero?

• They are less than zero.

• They are greater than zero.

• They are equal to zero.

• They cannot be compared to zero.

Which of the following is true for negative integers on a vertical number line?

• They are equal to zero.

• They are greater than zero.

• They are less than zero.

• They are greater than positive integers.

When comparing -2 and 0 on a vertical number line, which is correct?

• -2 is greater than 0.

• -2 is equal to 0.

• -2 is less than 0.

• -2 and 0 cannot be compared.

Which number is greater: 1 or -3, when using a vertical number line?

• 1 and -3 cannot be compared.

• 1 is less than -3.

• 1 is equal to -3.

• 1 is greater than -3.

In the set {-6, -10, -8}, which is the least number?

• -6

• -10

• -8

• None of the above

Order the numbers 9, 2, and 4 from least to greatest.

• 9, 4, 2

• 2, 4, 9

• 4, 9, 2

• 9, 2, 4

Which is the correct order from least to greatest: 2, -2, 0?

• 2, 0, -2

• -2, 0, 2

• 0, 2, -2

• 2, -2, 0

In the set {7, 5, -7, -5}, which is the greatest number?

• 5

• -5

• 7

• -7
