Lesson 1: Comparing and Ordering Integers
![Page 2: Lesson 1: Comparing and Ordering Integers. Number Line Points to the right of the zero (the origin) represent positive numbers. Points to the left of.](https://reader035.fdocuments.in/reader035/viewer/2022070413/5697bf9d1a28abf838c93854/html5/thumbnails/2.jpg)
Number Line Points to the right of the zero (the
origin) represent positive numbers. Points to the left of zero represent negative numbers. Zero is neither positive nor negative.
![Page 3: Lesson 1: Comparing and Ordering Integers. Number Line Points to the right of the zero (the origin) represent positive numbers. Points to the left of.](https://reader035.fdocuments.in/reader035/viewer/2022070413/5697bf9d1a28abf838c93854/html5/thumbnails/3.jpg)
Integers* The set of counting numbers, their
opposites, and zero; the members of the set (…,-2, -1, 0, 1, 2,…)

IntegersAll whole numbers (0, 1, 2…)
are integers, but not all integers are whole numbers.
![Page 5: Lesson 1: Comparing and Ordering Integers. Number Line Points to the right of the zero (the origin) represent positive numbers. Points to the left of.](https://reader035.fdocuments.in/reader035/viewer/2022070413/5697bf9d1a28abf838c93854/html5/thumbnails/5.jpg)
Give an example of an integer that is not a whole number.
![Page 6: Lesson 1: Comparing and Ordering Integers. Number Line Points to the right of the zero (the origin) represent positive numbers. Points to the left of.](https://reader035.fdocuments.in/reader035/viewer/2022070413/5697bf9d1a28abf838c93854/html5/thumbnails/6.jpg)
Counting numbers, whole numbers, and integers are examples of different sets of numbers. A set is a collection of items.
![Page 7: Lesson 1: Comparing and Ordering Integers. Number Line Points to the right of the zero (the origin) represent positive numbers. Points to the left of.](https://reader035.fdocuments.in/reader035/viewer/2022070413/5697bf9d1a28abf838c93854/html5/thumbnails/7.jpg)
How are the sets of whole numbers and integers different?
Set of integers(…,-3, -2, -1, 0, 1, 2, 3,…)
Set of whole numbers(0, 1, 2, 3,…)
![Page 8: Lesson 1: Comparing and Ordering Integers. Number Line Points to the right of the zero (the origin) represent positive numbers. Points to the left of.](https://reader035.fdocuments.in/reader035/viewer/2022070413/5697bf9d1a28abf838c93854/html5/thumbnails/8.jpg)
Absolute Value*The distance from the graph of a number to the origin on a number line.
![Page 9: Lesson 1: Comparing and Ordering Integers. Number Line Points to the right of the zero (the origin) represent positive numbers. Points to the left of.](https://reader035.fdocuments.in/reader035/viewer/2022070413/5697bf9d1a28abf838c93854/html5/thumbnails/9.jpg)
Absolute Value Absolute value is always a positive
number because it represents a distance.
The absolute value of -5 is what?
![Page 10: Lesson 1: Comparing and Ordering Integers. Number Line Points to the right of the zero (the origin) represent positive numbers. Points to the left of.](https://reader035.fdocuments.in/reader035/viewer/2022070413/5697bf9d1a28abf838c93854/html5/thumbnails/10.jpg)
Arrange these integers in order from least to greatest.
-3, 3, 0, 1
![Page 11: Lesson 1: Comparing and Ordering Integers. Number Line Points to the right of the zero (the origin) represent positive numbers. Points to the left of.](https://reader035.fdocuments.in/reader035/viewer/2022070413/5697bf9d1a28abf838c93854/html5/thumbnails/11.jpg)
Compare
Which is greater? -3 or -1
![Page 12: Lesson 1: Comparing and Ordering Integers. Number Line Points to the right of the zero (the origin) represent positive numbers. Points to the left of.](https://reader035.fdocuments.in/reader035/viewer/2022070413/5697bf9d1a28abf838c93854/html5/thumbnails/12.jpg)
Compare
Now which is greater? The absolute value of -3 or the absolute value of -1?

Graphing points on a number line
How would we graph the points -4, -2, 0, 2, and 4 on a number line?
![Page 14: Lesson 1: Comparing and Ordering Integers. Number Line Points to the right of the zero (the origin) represent positive numbers. Points to the left of.](https://reader035.fdocuments.in/reader035/viewer/2022070413/5697bf9d1a28abf838c93854/html5/thumbnails/14.jpg)
What kind of set are these numbers a part of?
(…-4, -2, 0, 2, 4,…)
![Page 15: Lesson 1: Comparing and Ordering Integers. Number Line Points to the right of the zero (the origin) represent positive numbers. Points to the left of.](https://reader035.fdocuments.in/reader035/viewer/2022070413/5697bf9d1a28abf838c93854/html5/thumbnails/15.jpg)
