Revision Notes Class 3 Mathematics Chapter 9 - How Many Times?
How Many Times?
How many means is the number or counting of anything like there are four chairs, there are two apples.
Then what is meant by time is simply multiplication or it is repeating about anything.
Solved example 1: The almirah has 5 shelves. There are 6 books on each shelf. How many books are in the almirah?
Ans: Given, Number of books on each shelf =6
And the total number of shelves = 5
Then total books in almirah = 5 times 6 = 5 × 6 = 30 books.
Hence the total number of books in the almirah = 30.
Solved example 2: Three pens were given to each student in the class. If there were 34 students, How many pens were given in all?
Ans: Total students in class = 34
Each student gets 3 pens.
So, total number of pens given in class = 34 times 3 = 34 × 3
Hence total pens given in class = 102.
Animals having long and attractive legs are known as leggy animals.
There are different numbers of legs for different animals.
Examples: Four-legged animals, eight legs animals etc. Goats are four-legged animals and octopuses have eight legs.

Solved example 3: Octopus has 8 legs, then how many legs altogether do 7 octopuses have?
Ans: Given, the Number of legs in one octopus = 8.
The number of octopuses = 7.
Total number of legs in 7 octopuses = 8 times 7 = 8×7 =56.
Hence the number of legs in 7 octopuses = 56.
How to Find Numbers by Counting
By counting, we can say there are 3 spiders.
Solved Example 4: If a spider has 8 legs, So how many total legs for 3 spiders?
Ans: Here, one spider has 8 legs.
Total number of spiders = 3
Then, the total number of legs for 3 spiders = (8 + 8 + 8)
= 3x8= 24
Therefore, the total number of legs for 3 spiders is 24.
How to Find Numbers Without Counting

Here we find the number of flowers in the flower bed without counting them one by one.
The flower bed has 4 columns and each column has 6 flowers so the total number of flowers will be 4 times 6.
The total number of flowers in the flower bed = $4\times 6= 24$ flowers.
Jumping the Number
3 Steps each time: In every step, the number is increased by 3.
4 Steps each time In every step the number is increased by 4.
7 Steps each time In every step the number is increased by 7.
Solved Example 5: Find the missing number in 100, 104, 108, ……., 116, 120.
Ans: The difference between 104 and 100 is 4, likewise between 108 and 104 is 4. So, we can say that in every step the number is increased by 4. Therefore the pattern is the difference between two consecutive numbers is 4 and hence the next number after 108 is ( 108 + 4 ) = 112.
Therefore the required pattern is
100 , 104 , 108 , 112, 116 , 120.
In this play, we take some sticks and arrange them horizontally and vertically then we figure how many times sticks are crossing each other.
Also, we can make tables by using sticks.
Here, 5 Sticks vertically and 4 sticks horizontally are placed and they are crossing each other 4 times 5.
Solved Example 6: How many different arrangements are possible for 24 sticks.
Ans: To find possible stick arrangements in 24 sticks. First, you need to find all possible multiples of 24: 2, 4, 6, 8, 12, 24.
Possible arrangements 212, 38, 64, 122, 83, 46.

Q1. Sonu bought 5 packets of biscuits. Each packet has 6 biscuits. How many biscuits did Ramu buy?
Q2. In the figure below, find how many 2 in each row.
Arrangement of Birds
Q3. How much do 3 pencil boxes cost in rupees?
Ans: 1. 5 times 6 Sonu brought 30 biscuits.
Row 1 one time 2.
Row 2 two times 2.
Row 3 three times 2.
Row 4 four times 2.
Row 5 five times 2.
The cost of 3 pencil boxes will be 30 rupees.
Given that each pencil box cost = Rs. 10.
So, the Cost for 3 pencil boxes = 3 times Rs. 10.
Therefore the cost of 3 pencil boxes will be 30 rupees.
