Lesson 7- Ordering Decimals
Objective
At the end of this lesson, students should be able to arrange decimals in ascending or descending order.
Ordering decimals means, arranging decimal numbers in an organized manner. Decimals can be arranged in ascending or descending order
With the knowledge from comparing decimals, you can identify the largest decimal number in a list, the next larger decimal, smallest, etc.
