Rainy Seasons for Class 4 Maths
Around the whole year, we feel different types of atmospheres. Here students will learn about rainy seasons when we feel the temperature is hotter or colder. Also, this will inform the students about the rainy season’s flowers and rainy seasons fruits in India; when is the rainy season? The discussion relates these points with bar graphs, addition and subtraction, Comparing and ordering numbers and measuring length.
About Rainy Seasons:

The climate varied in west Bengal, and we experienced mainly three seasons around the year: winter, summer, and monsoon.
We also call the rainy season in the name monsoon.
When Is the Rainy Season?
The rainy season comes after the summer, starting in June and extending up to September.

In different cities of West Bengal effect of rain is different; also, it depends on the different temperatures in other places.
Average Temperature and Rainfall of Different Cities in West Bengal During the Rainy Season:
City | Average temperature(°C) | Average rainfall (mm) |
---|---|---|
Darjeeling | 16.4 | 2796 |
Siliguri | 28.1 | 2651 |
Jalpaiguri | 28.0 | 2674 |

Addition and Subtraction
Question 1:
Boni is Planning a Trip to Darjeeling and Digha in the Monsoon. For That Trip, She Was Checking the Average Rainfall for Both Places on Google.
Then Find the Difference Between the Average Rainfall of the Two Cities.
Answer 1:
The average rainfall in Darjeeling is 2796 mm
Average rainfall in Digha = 1192 mm
The difference between rainfall is

So, the average rainfall difference between Darjeeling and Digha is 1604 mm.
Question 2:
Rabi is Planning a Trip to Siliguri and Behrampore in the Monsoon. She Checks the Average Rainfall for Both Places on Google. Between Two Cities, in Which City Does the Most Rainfall Occur?
Then Represent the Difference as a Combination of the Miter, Decimeter, Centimeter, and Millimeter.
Answer 2:
Part 1:
The average rainfall in Siliguri is 2651 mm.
Average rainfall in Behrampore = 1036 mm.
we know 2651 > 1036
So, Siliguri receives higher rainfall than Behrampore.
Now, the difference is of rainfall is

Part 2:
We know that 1000 mm = 1 m
100 mm = 1 dm
10 mm = 1 cm
Now, 1615 mm
= 1000 mm + 600 mm + 10 mm + 5 mm
= 1 m + 6 dm + 1 cm + 5 mm
Vertical Bar graph
Question 3:
On a News Channel Puja Saw, the Average Rainfall in Malda Is 1207 mm, Bankura Is 1227 mm, Asansol Is 1140 mm, and Digha Is 1192 mm. Represent the Rainfall in a Vertical Bar Graph.
Answer 3:
According to the news channel,
In Malda, the average rainfall is 1207 mm,
In Bankura, the average rainfall is 1227 mm,
In Asansol, the average rainfall is 1170 mm and
In Digha, the average rainfall is 1192 mm.
The bar graph is given below according to the given data:

Comparing and Ordering Number
Question 4:
Rita Read About the Average Rainfall of Different Cities in West Bengal, During the Monsoon and Arrange the Cities in Ascending and Descending Order According to Average Rainfall.
- What Is the Ascending Order?
- What Is the Descending Order?
Answer 4:
From the given table:
The rainfall in Darjeeling = 2796 mm,
Siliguri = 2651 mm, Jalpaiguri = 2674 mm, Malda = 1207 mm, Shantiniketan =
1510,
Behrampore = 1036 mm, Krishnagar = 1348 mm, Asansol = 1140 mm,
Bankura = 1227 mm, Kolkata = 1358 and Digha = 1192 mm.
Part a:
Now, the ascending order is:
1036 mm, 1140 mm, 1192 mm, 1207 mm, 1227 mm, 1348 mm,
1358 mm, 1510 mm, 2651 mm, 2674 mm, 2796 mm
The cities in ascending order are:
Behrampore = 1036 mm, Asansol = 1140 mm, Digha = 1192 mm,
Malda = 1207 mm, Bankura = 1227 mm, Krishnagar = 1348 mm,
Kolkata = 1358 mm, Shantiniketan = 1510 mm, Siliguri = 2651 mm,
Jalpaiguri = 2674 mm, Darjeeling = 2796 mm.
Part b:
Now, the descending order is:
2796 mm, 2674 mm, 2651 mm, 1510 mm, 1358 mm, 1348 mm,
1227 mm, 1207 mm, 1192 mm, 1140 mm, 1036 mm.
The cities in descending order are:
Darjeeling = 2796 mm, Jalpaiguri = 2674 mm, Siliguri = 2651 mm,
Shantiniketan = 1510 mm, Kolkata = 1358 mm, Krishnagar = 1348 mm,
Bankura = 1227 mm, Malda = 1207 mm, Digha = 1192 mm,
Asansol = 1140 mm, Behrampore = 1036 mm.
