3. Least to Greatest Or Greatest to Least
Least to greatest means that you order numbers from the smallest to the largest. The smallest number is always listed first.
Example: 1 , 2 , 3
Greatest to least means that you order numbers from the largest to the smallest. The largest number is always listed first.
Example: 5 , 4 , 3
You try… , 8 , 7
These three numbers are ordered from:
A) Least to greatest B) Greatest to least

4. How to Order Numbers
Start by comparing two numbers (review the steps).
Example: 2, ,434
Now that you know which number is smaller and which is bigger, compare a new number to the smaller number.
Example: 2, ,244
Since 2,244 is even smaller, it is the smallest of the three numbers. If you were ordering the numbers from least to greatest, it would be the first number you list. If you were ordering from the greatest to least, it would be the last number you list.
Example: least to greatest 2,244 , 2,434 , 2,444
greatest to least 2,444 , 2,434 , 2,244

5. How to Order Numbers
Let’s try that again. Start by comparing two numbers (review the steps).
Example: 2, ,434
Now that you know which number is smaller and which is bigger, compare a new number to the smaller number.
Example: 2, ,441
Since 2,441 is bigger than 2,434, you know 2,434 is the smallest number… but you still need to compare 2,441 and 2,444.
Example: 2, ,441
Now you can order the numbers least to greatest:
2,434 , 2,441 , 2,444
Do you think you could order them from greatest to least?
