Ascending Order & Descending Order | Maths for UKG PDF Download

Introduction

In this chapter, we will learn about two important ways to arrange numbers: Ascending Order and Descending Order. These methods help us organize numbers from the smallest to the largest or from the largest to the smallest. 

Objectives

• Understand what Ascending Order means.
• Understand what Descending Order means.
• Learn how to arrange numbers in Ascending and Descending Order.
• Practice with examples.

Ascending Order

Steps to Arrange Numbers in Ascending Order

• Look at all the numbers you have.
• Find the smallest number among them.
• Put that smallest number first.
• Now, look for the next smallest number among the remaining numbers.
• Keep doing this until you have arranged all the numbers from smallest to largest.

Example - Ascending Order
Let's say we have these numbers: 8, 2, 5, 10, and 3.

• Step 1: The smallest number is 2.
• Step 2: Put 2 first.
• Step 3: Our list now looks like this: 2.
• Step 4: The next smallest number is 3.
• Step 5: Add 3 to our list: 2, 3.
• Step 6: Keep going until all numbers are in order: 2, 3, 5, 8, 10.

Descending Order

Steps to Arrange Numbers in Descending Order

• Look at all the numbers you have.
• Find the largest number among them.
• Put that largest number first.
• Now, look for the next largest number among the remaining numbers.
• Continue doing this until you have arranged all the numbers from largest to smallest.

Example - Descending Order
Let's use the same numbers as before: 8, 2, 5, 10, and 3.

• Step 1: The largest number is 10.
• Step 2: Put 10 first.
• Step 3: Our list now looks like this: 10.
• Step 4: The next largest number is 8.
• Step 5: Add 8 to our list: 10, 8.
• Step 6: Keep going until all numbers are in order: 10, 8, 5, 3, 2.

Conclusion

In this chapter, we've learned how to arrange numbers in Ascending Order (from smallest to largest) and Descending Order (from largest to smallest). These skills can help us organize things in real life, like our toys, candies, or even our friends by height.
