Grouping and Sharing – Complete Guide For Class 2 Math Chapter 8

Welcome to iPrep, your Learning Super App. Our learning resources for the chapter, Grouping and Sharing in Mathematics for Class 2nd are designed to ensure that you grasp this concept with clarity and perfection. Whether you’re studying for an upcoming exam or strengthening your concepts, our engaging animated videos, practice questions and notes offer you the best of integrated learning with interesting explanations and examples.

Using simple and familiar examples, Chapter 8, “Grouping and Sharing,” introduces students to the basic concepts of multiplication and division. While sharing helps us split things evenly throughout groups, grouping teaches us how to arrange things together in equal sets. These concepts are significant because they form the foundation for division as equal sharing or distribution and multiplication as repeated addition.

By the end of this chapter, students will understand how to represent multiplication using grouping, how sharing and division are related, and how both operations simplify everyday tasks. Students will also see how math may be used in practical contexts through a variety of examples and enjoyable exercises.

Grouping and Addition as Repeated Multiplication

Understanding Grouping

Grouping is the process of arranging items into equal sets. We make sure that there are the same amount of items in each group when we group things. Grouping gives the concept of repeated addition, which eventually leads to multiplication, and helps the quick counting of huge numbers of things. 

Example 1: Grouping with Sweets

Imagine you have 12 sweets, and you want to group them equally among your friends. If you make 4 groups and each group has 3 sweets, this means that you’ve grouped the sweets into equal sets.

Activity 1: Grouping Objects

• Take 12 small objects like buttons or candies. Now, try making 3 groups. How many objects are there in each group? Then, try making 4 groups. Count how many objects are in each group.

Grouping as Repeated Addition

Repeated addition means adding the same number over and over. This is the first step towards understanding multiplication.

Example 2: Grouping with Repeated Addition

Let’s say you have 3 flowers in each of 4 pots. How many flowers are there in total? 

We can find the total by adding the flowers in each pot:

3 + 3 + 3 + 3 = 12

This shows that there are 12 flowers in total.

Activity 2: Counting Repeatedly

• Draw 4 boxes, and inside each box, draw 3 circles. Now, add the circles in all the boxes to find out how many there are altogether. Write the repeated addition statement and then count the total.

Linking Grouping to Multiplication

Multiplication is a faster way of doing repeated addition. Instead of adding the same number multiple times, we can simply multiply the number of items in one group by the number of groups.

Example 3: Using Multiplication for Grouping

In the previous example, we added 3 flowers four times:

3 + 3 + 3 + 3 = 12

Instead of adding, we can multiply:

3×4 = 12

This means there are 12 flowers in total.

Activity 3: Exploring Multiplication

• Take 5 pencils and place them in 2 groups. Now, multiply the number of pencils in one group (5) by the number of groups (2):

5×2 = 10

You have a total of 10 pencils. 

Relating Grouping to Real-Life

Grouping is something we do all the time. For example, when you set the table for dinner, you might put the same number of spoons, plates, and glasses at each place. Grouping helps us organize things efficiently.

Example 4: Grouping in Real Life

Imagine you are arranging chairs for 2 rows in a classroom, and each row has 4 chairs. Instead of counting all the chairs one by one, you can multiply:

2×4 = 8

This tells you that there are 8 chairs in total.

Sharing and Division

Understanding Sharing

Sharing means dividing things equally among groups. When we share objects equally, each group gets the same amount, and this introduces the concept of division.

Example 5: Sharing with Sweets

Suppose you have 15 sweets, and you want to share them equally among 5 friends. How many sweets will each friend get? We can divide the total number of sweets by the number of friends:

15 ÷ 5 = 3

Each friend will get 3 sweets.

Activity 4: Sharing Objects

• Gather 12 buttons or pebbles, and try sharing them equally between 3 friends. How many does each person get? Now try sharing them between 4 friends. Notice how sharing helps you divide things equally.

Division as Equal Sharing

Division is the process of splitting a number into equal parts. When we divide, we find out how many items each group gets or how many groups we can make.

Example 6: Using Division

If you have 20 candies and want to share them equally among 4 friends, how can you do it? 

You divide the total number of candies by the number of friends:

20 ÷ 4 = 5

Each friend will get 5 candies.

Activity 5: Division Practice

• Take 16 toys and try dividing them equally among 4 groups. How many toys are in each group? Now try dividing the toys into 2 groups. 

Connecting Sharing to Division

Sharing helps us understand division. Whenever we share things equally, we are performing a division operation.

Example 7: Division in Real Life

Imagine you have 24 marbles, and you want to divide them into 6 bags. You need to figure out how many marbles will go in each bag. 

By dividing, you can find out:

24 ÷ 6 = 4

So, each bag will have 4 marbles.

Relating Division to Real Life

The division is very useful in real life. For example, if you want to share food or toys with friends, or if you want to divide items evenly between groups, division helps you do that easily.

Example 8: Dividing Things Equally

If there are 16 cupcakes and 2 children, how many cupcakes will each child get? 

You can divide the total number of cupcakes by the number of children:

16 ÷ 2 = 8

Each child will get 8 cupcakes.

Word Problems Using Grouping and Sharing

Now that we understand grouping and sharing, let’s solve some simple word problems to practice what we’ve learned.

Word Problem 1: Grouping with Multiplication

Rani has 4 baskets, and each basket has 6 apples. How many apples does she have in total? 

We can use multiplication to find the answer:

4 × 6 = 24

Rani has 24 apples.

Word Problem 2: Sharing with Division

Rani’s mother baked 20 cookies and wants to share them equally among 4 children. How many cookies will each child get? 

We can use division to find the answer:

20 ÷ 4 = 5

Each child will get 5 cookies.
