Glimpses of Class 2 Maths Chapter 2 – Counting in Groups t

Class 2 Maths Chapter 2 – Counting in Groups teaches about counting numbers in groups. This lesson also teaches the ordinal numbers. 

What is Counting in Groups?

Grouping means to divide things or to organize things into equal sets or groups. We can count anything in groups such as a group of children, a set of pencils or a set of toys, etc. We are getting one kind of thing together. 

We see many things around us like books, pencils, notebooks, etc. We must put each kind of thing in different sets. This way we can be organized and we can easily identify things. 

Ordinal Number

The number that tells us the position of something in a list or series is an ordinal number. For example: 1st, 2nd , 3rd, 4th, 5th, 6th, 7th, ……. 

Now let us apply both the topics in real life application.

Meenu has many toys. She has cars, dolls, blocks, etc. Meenu’s mother gave her three baskets and asked her to organize all her toys in the toy baskets. Meenu took the cars and put them in the first basket then she put the dolls in the second basket. Finally, she put the blocks in the third basket. In this way Meenu organized all her toys and helped her mother in cleaning. Meenu’s mother was very happy with her. She gave two chocolates to Meenu. 

In school, the class teacher asked the children to stand in a line. Radhika, Rina, Ayesha, Trisha, Sumit, Mansi, Raghav, Puja, Evan and Raj stood in a line. Can you tell me what is the position of Trisha and Evan in the line? 

The answer is Trisha is in the 4th position and Evan is in the 9th position. This is the way Ordinal numbers work. It tells us the position of something or someone. 

Conclusion

We have learnt how to group objects in sets and how we identify the position of something in the list. This will help the students to be organized with their own things. Counting in groups and ordinal numbers are foundational concepts in Maths. These concepts are preparing them to solve complex mathematical questions in future.
