The Fish Tale Class 5 Notes: CBSE Maths Chapter 1

Size of the Fish

• Fishes can have very different sizes. The smallest fish size is 1cm and the largest size is approximately 18 m long.

• Largest fish in the world is the whale shark. 

• Whale fish are different from other fishes. Whales breathe through their noses just like humans, not like other fishes.

• Fishes have no noses; they take in water, not air.

• Whales give birth to babies but other fishes lay eggs.

• Whale sharks look very big and dangerous but they are pretty harmless.

• In (Malayalam) Kerala fish are called “meen”.

Solved Example 1.  If the weight of one child is 20 kg, a shark is equal to 12 children like you put together will weigh about …?

Sol: Weight of one child = 20 kg.

Then weight of 12 children = 20 kg 12 = 240 kg.

The weight of 12 children is equal to one shark.

So, the weight of one shark = 240 kg.

The Shape of the Fish

• The Shapes of fishes are combinations of the shape of triangle, square and circle shape. In fish shape the triangle is the tail of the fish, the square is the body and the circle is the eye of the fish.
  
  

Eye of the fish

• Example: Different shapes of fish.

Difference Between Whale Tail and Another Fishtail.

Whale	Other fish
Whale’s tails almost look like two legs	Fishtail stands flat along its body.

School of Fish

• When fish swim together in the river or sea in big groups called “School” of fish. 

• In school they feel secure and safe.

Boat

• Fishermen use boats to go to the sea and they are going up and down with waves.

• There are different types of boats around the world. And a simple boat made from logs of wood tied together.
  
  

Log Boat

• Fishermen use the sun for their direction sometimes they won’t get direction also.

• Boat speed is different in different types of boats. Some boats have motors and their speed is approx 20 km in one hour.
  
  

Motor boat

• Fishermen use boats to catch fish by using nets.
  
  

Catch fish by using nets

Solved Example 2: How long it will take to go a distance of 20 km. A log boat can travel 4 km in one hour.

Ans: Speed of a log boat = 4 km per hour.

log boat travel in two hour = 4 km $\times$ 2 = 8 km.

log boat travel in three hour = 4 km $\times$ 3 = 12 km.

log boat travel in three hour = 4 km $\times$ 4 = 16 km.

Then log boat travel in Five hour = 4 km $\times$ 5 = 20 km.

Therefore log boats will take 5 hours to complete a distance of 20 km.

Solved Example 3: How long it will take to go a distance of 100 km. If a motorboat can travel 20 km in one hour.

Ans: Speed of a Motorboat = 20 km per hour.

Motor boat travel in two hour = 20 km $\times$ 2 = 40 km.

Motor boat travel in three hour = 20 km $\times$ 3 = 60 km.

Motor boat travel in three hour = 20 km $\times$ 4 = 80 km.

Then Motor boat  travels in Five hour = 20 km $\times$ 5 = 100 km.

Therefore log boats will take 5 hours to complete a distance of 100 km

Different Types Of Boats and Their Capacity To Carry Fish and Their Speed.

Estimation of Numbers

• In maths, estimation means the near value of any number and quality.

• Look at the number estimation on the number line.
  
  

Number 10.9

Number 5.3

Example 

Practice Question

Q1. Shivam took a loan of Rs.6000 to buy a net. He paid back Rs. 540 every month for one year. How much money did he pay back to the bank? 

Ans:  Rs. 6480

Q2. Name two things that are lying to your east.

Ans: Students, please give your own answer for this.

Q3. How much time will the boat take to reach 100 km, if the boat speed is 25 km in one hour?

Ans: 4 Hour.
