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.
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

FAQs on The Fish Tale Class 5 Maths Chapter 1 CBSE Notes - 2025-26
1. What are the main mathematical concepts I should revise from Chapter 1, 'The Fish Tale'?
For a quick revision of 'The Fish Tale', you should focus on these key concepts:
Large Numbers: Understanding, reading, and writing numbers in lakhs and crores.
Basic Operations: Applying addition, subtraction, multiplication, and division to solve problems related to money, weight, and distance.
Measurement: Concepts of speed (km/hr), weight (kg), and length (m).
Geometry: Recognising basic shapes like triangles and circles used to draw fish.
2. How does the chapter use the whale shark to teach about large numbers?
The chapter introduces the whale shark, one of the biggest fish, to help you visualise and work with large numbers. By mentioning its length (e.g., 18 metres) and weight (e.g., 16,000 kg), it provides a real-world context for numbers that are much larger than what you use in daily life, making them easier to comprehend.
3. What is the concept of speed, distance, and time as explained in 'The Fish Tale'?
The chapter explains the relationship between speed, distance, and time using boats. For example, it states a log boat travels at a speed of 4 km per hour. This means in one hour, it covers a distance of 4 km. This concept is a basic introduction to calculating how long a journey will take or how far one can travel in a given time.
4. How is drawing a fish connected to geometry in this chapter's summary?
Drawing a fish using shapes like triangles for fins and circles for eyes is a creative way to revise basic geometry. It demonstrates how complex figures can be constructed from simple, familiar shapes, which is a foundational idea in geometry and art.
5. What's the quick way to calculate earnings from selling fish, as shown in the chapter?
To quickly calculate total earnings, you multiply the total quantity of fish sold (in kg) by the selling price per kg. This concept is a key part of the chapter's focus on practical, real-world maths used in a fish market scenario.
6. Why is it important to understand the difference between a log boat and a motorboat for maths problems in this chapter?
Understanding the difference is crucial because it affects the calculations. The key differences for maths problems are speed and capacity. A log boat is slow (around 4 km/hr) and has a small capacity, while a motorboat is fast (around 20 km/hr) and carries more. This changes the outcome of problems related to travel time, distance covered, and the amount of fish caught.
7. How does the 'fish market' theme help in revising the four basic mathematical operations?
The fish market theme provides a practical setting to revise all four operations:
Addition: To calculate the total weight of fish or total money spent.
Subtraction: To find the remaining money or calculate profit.
Multiplication: To find the total cost of fish when the rate per kg is known.
Division: To calculate the price per kg or to share earnings equally.
8. What is a 'crore', and how is it related to a 'lakh' in this chapter?
In the Indian numbering system, a 'crore' is a large number. One crore is equal to one hundred lakhs (1,00,00,000). The chapter uses these terms in the context of large-scale fishing businesses, like the cost of a trawler or the annual earnings of a fish worker's bank, to build familiarity with the place value system for large numbers.
9. How do these revision notes for 'The Fish Tale' help in approaching word problems?
These notes help by summarising the core logic for different scenarios. When you revise concepts like loan repayment, speed calculation, or finding the total cost, you also revise the specific mathematical operation needed for each. This makes it easier to decode word problems and apply the correct formula quickly during exams.
