Objectives Of Learning The Chapter Decoration For Festivals

The objective of learning CBSE Class 2nd Math, Chapter 6 – Decoration for Festivals is to help students understand and apply the concepts of two-digit addition and subtraction in real-life scenarios, specifically within the context of festive celebrations. By engaging with relatable examples, such as counting decorations, sweets, and gifts, students will develop their mathematical skills while recognizing the practical significance of math in organizing and enhancing holiday experiences. This chapter aims to foster a positive attitude towards math by demonstrating how it can be both fun and useful during joyful occasions, ultimately preparing students to confidently tackle everyday arithmetic challenges.

Understanding Two-Digit Addition

Addition means putting things together to find the total number. Let’s start by understanding how to add two-digit numbers. The key is to separate the numbers into tens and ones. This way, it becomes easier to solve the problems.

Example 1: Adding Two-Digit Numbers for Decoration

Suppose you are decorating your home for a festival. You have 23 colorful lamps, and your family brings 16 more. How many lamps do you have now? Let’s break it down and add step by step.

• Step 1: Write the numbers in columns:

• Step 2: Add the ones (3 + 6 = 9).
• Step 3: Add the tens (2 + 1 = 3).

So, you now have 39 lamps in total.

Activity 1: Lamp Counting

• Draw 20 lamps on one side of your paper and 16 more on the other side. Now count all the lamps by adding them together. Can you get the total number of lamps? Yes! The answer is 36.

Example 2: Adding Decorations

You have 45 paper flowers, and your friend gives you 32 more. Let’s add these two numbers to find out how many paper flowers you now have.

• Step 1: Write the numbers in columns:

• Step 2: Add the ones (5 + 2 = 7).
• Step 3: Add the tens (4 + 3 = 7).

The total number of paper flowers you have is 77.

Activity 2: Festival Garland

• Imagine you are making a garland for a festival using 52 flowers, and your neighbor adds 32 more. Draw the flowers on a sheet of paper and count them by adding. What is the total number? Yes, it’s 84!

Subtraction: Taking Away to Organize

Subtraction means taking something away to see what is left. During festivals, subtraction helps us figure out how many items remain after we use or give away some of them.

Example 1: Subtracting Decorations

You start with 64 festive lights, but after decorating the house, you use up 28 of them. How many lights are left?

• Step 1: Write the numbers in columns:

• Step 2: Since 4 is smaller than 8, we need to borrow from the tens. This makes 14 in the one’s place and 5 in the tens.

• Step 3: Subtract the ones (14 – 8 = 6).
• Step 4: Subtract the tens (5 – 2 = 3).

So, 36 lights are left after decorating.

Activity 3: Festive Lights

• Draw 60 lights on one side of your paper. Now, take away 20 of them (you can cross them out). Count how many lights are left. Did you get 40?

Example 2: Subtracting Sweets

You have 52 sweets, and you give 19 to your friends. How many sweets are left?

• Step 1: Write the numbers in columns:

• Step 2: Since 2 is smaller than 9, we borrow from the tens, making it 12 in the ones place and 4 in the tens.

• Step 3: Subtract the ones (12 – 9 = 3).
• Step 4: Subtract the tens (4 – 1 = 3).

You now have 33 sweets left.

Activity 4: Sharing Sweets

• Imagine you have 48 sweets. Draw 48 sweets on your paper and then give away 19 sweets by crossing them out. Now count how many are left. The correct answer is 29!

Understanding Word Problems

Word problems are real-life situations where you need to figure out the solution using math. During festivals, you may face many situations where addition or subtraction is required. Let’s look at some examples.

Example 1: Festival Balloons

For a festival party, you buy 34 balloons. Later, you buy 27 more balloons. How many balloons do you have in total?

• Step 1: Write the numbers in columns:

• Step 2: Add the ones (4 + 7 = 11; write 1 in the one’s place and carry 1 to the tens place).

• Step 3: Add the tens (3 + 2 = 5; now add the carry-over 1: 5 + 1 = 6).

The total number of balloons is 61.

Example 2: Subtracting Rangoli Colors

You have 70 packets of rangoli colors. After decorating, you use 35 packets. How many packets of rangoli colors are left?

• Step 1: Write the numbers in columns:

• Step 2: Since 0 is smaller than 5, we borrow from the tens, making it 10 in the ones place and 6 in the tens.

• Step 3: Subtract the ones (10 – 5 = 5).
• Step 4: Subtract the tens (6 – 3 = 3).

There are 35 packets of rangoli colors left.
