Lesson 2- Ordering Numbers

Objective:

At the end of this lesson, students should be able to order numbers in ascending and descending order.

Ordering numbers involves arranging numbers from the least to the greatest or from the greatest to the least.

In ordering numbers, we may arrange them in these orders;

a) Ascending order—arranging from smallest to largest

b) Descending order—arranging from largest to smallest

1) 3480, 7892, 1567, 5845

2) 211, 121, 201, 311, 131

3) 5290, 2590, 920, 5209

Solution

1) 7892, 5845, 3480, 1567

2) 311, 211, 201, 131, 121

3) 5290, 5209, 2590, 920

Example 2

Arrange the following numbers in ascending order.

1) 3480, 7892, 1567, 5845

2) 211, 121, 201, 311, 131

3) 5290, 2590, 920, 5209

Solution

1) 1567, 3480, 5845, 7892

2) 121, 131, 201, 211, 311

3) 920, 2590, 5209, 5290
