NCERT Revision Notes for Class 1 Maths Chapter 11: How Many Times? – Free PDF Download

Chapter 11 of Class 1 Joyful Mathematics, How Many Times?, introduces the earliest, informal idea of repeated addition — counting how many times an action happens or how many equal groups make up a total, which later grows into multiplication.

Key Concepts

Repeated addition: adding the same number again and again, such as 2 + 2 + 2, instead of adding different numbers each time.

Equal groups: groups that all have the same number of objects in them, like 3 groups of 2 flowers each.

Counting “how many times”: counting how many times a small group or action repeats to make up the total, such as clapping 3 times or jumping 4 times.

Doubling: a special case of repeated addition where a number is added to itself once, such as 4 + 4 = 8.

Connecting groups to totals: understanding that the total number of objects depends on both the size of each group and how many groups there are.

Worked Examples

Example 1

There are 3 flower pots, and each pot has 2 flowers. How many flowers are there in total? 2 + 2 + 2 = 6 flowers.

Example 2

A child claps 4 times, clapping twice each time. How many claps are made in total? 2 + 2 + 2 + 2 = 8 claps.

Example 3

Double the number 5. 5 + 5 = 10.

Quick Recap

• Repeated addition means adding the same number multiple times.
• Equal groups have the same number of objects in every group.
• “How many times” tells us how many equal groups or repeated actions make up the total.
• Doubling means adding a number to itself once.
• This chapter is an early, informal step toward multiplication tables in later classes.

Common Mistakes to Avoid

• Adding groups of different sizes together and still calling it repeated addition.
• Losing count of how many times a group has been added while solving the sum.
• Confusing “how many groups” with “how many objects in one group” — both numbers matter for finding the total.
• Making an error while doubling larger numbers due to careless addition.
• Assuming repeated addition always uses only two groups; sometimes there are three or more equal groups.

Home Practice Tips

• Use small objects, like buttons or beads, arranged in equal groups, and practise adding them repeatedly.
• Play a clapping or jumping game where the child repeats an action a set number of times and counts the total.
• Practise doubling small numbers up to 10 using fingers or objects.
• Ask the child to make three equal groups of 3 objects each and find the total by repeated addition.
• Connect this to real life, like counting total wheels on 3 tricycles with 3 wheels each.

Frequently Asked Questions

Q1. Is this chapter teaching multiplication?
Not formally — it introduces the idea of repeated addition and equal groups informally, which becomes the foundation for multiplication tables taught in later classes.

Q2. What is the difference between repeated addition and normal addition?
Normal addition can join groups of different sizes, while repeated addition specifically adds the same number again and again.

Q3. How can I explain “equal groups” to my child simply?
Show groups of objects with the same count in each, like 2 apples in every basket, and explain that each group has exactly the same amount.

Q4. What is doubling, and why is it introduced here?
Doubling means adding a number to itself, like 3 + 3; it is introduced as a simple, common case of repeated addition that children will use often later.

Q5. How does this chapter connect to future maths chapters?
Understanding equal groups and repeated addition here directly supports learning multiplication tables and division concepts in later classes.
