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.

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

Subtraction of numbers

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

Subtraction of numbers

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:
