Understanding Absolute Values and Order

In this lesson, students learn about the relationship between absolute value and order. The teacher introduces vocabulary such as ascending and descending order, and provides examples. Students are guided through creating inequality statements using a set of integers, and then calculate the absolute values of these numbers. The lesson concludes with reordering the numbers based on their absolute values and a summary of the key points.

What does ascending order mean?

• Ordering numbers based on their absolute value

• Ordering numbers randomly

• Ordering numbers from greatest to least

• Ordering numbers from least to greatest

Which of the following is an example of descending order?

• 2, 4, 7, 9

• 9, 7, 4, 2

• 1, 3, 5, 7

• 0, -1, -2, -3

What is the first step in writing an inequality statement for a set of numbers?

• Start with the number closest to zero

• Start with the number with the highest absolute value

• Start with the largest number

• Start with the smallest number

Which number has the smallest absolute value?

• -1

• -12

• 5

• 0

How does the order of numbers change when considering their absolute values?

• The order is based on the magnitude of the numbers

• The order becomes random

• The order remains the same

• The order is reversed

What is the absolute value of -9?

• 18

• -9

• 0

• 9

In the context of absolute values, what does it mean to reorder numbers?

• Order them randomly

• Order them from least to greatest based on their absolute values

• Order them based on their original values

• Order them from greatest to least

Which of the following is the correct ascending order of absolute values for the numbers: -12, 5, -1, 0?

• 5, 1, 0, 12

• 1, 0, 5, 12

• 12, 5, 1, 0

• 0, 1, 5, 12

What is the absolute value of 0?

• Undefined

• -1

• 1

• 0

If you have any questions about the lesson, what should you do?

• Ask a friend

• Search online

• Make notes and ask in class

• Ignore them
