Find the hidden numbers.
Numbers put in this box get 
multiplied by a number and come out.
(a) Can you guess the multiplier if 
you see the 4 numbers coming 
out of the box?
(b) Is there more than one possible 
multiplier?
(c) What numbers might have been 
put inside the box? 
Share your thoughts in the class.
You can also play this game with your friends.
The multipliers 1, 2, and 4 that you found above are the factors of the 
numbers that have come out of the box, that is, 28, 36, 48, and 72. 
In fact, these are the common factors of all the numbers. The numbers 28, 
36, 48, and 72 are multiples of 1, 2 and 4.
The product of two or more factors gives a multiple.
A number, when arranged in an array, shows the factors of that number. 
Are there other numbers that are factors of 15? Try to make other arrays 
for the number 15.
Let us make arrays for the number 12.
3 × 5 = 15

3 × 4 = 12
2 × 6 = 12

FAQs on NCERT Textbook: Animal Jumps - Mathematics (Maths Mela) Class 5 - New NCERT

1. What are some of the key adaptations that allow animals to jump effectively?
Ans.Animals that jump have several adaptations, such as strong leg muscles, specialized tendons, and flexible joints. These adaptations enable them to generate the necessary force to propel themselves into the air. For instance, frogs have powerful hind legs and elastic tendons that store energy when they crouch, helping them leap great distances.
2. Which animals are known for their impressive jumping abilities?
Ans.Some animals are particularly renowned for their jumping skills. For example, kangaroos are famous for their long-distance jumps, aided by their strong hind legs and large tails for balance. Similarly, grasshoppers can leap many times their body length thanks to their strong hind legs, and frogs are also excellent jumpers, often using their powerful legs to escape predators.
3. How do different environments influence the jumping abilities of animals?
Ans.Different environments play a significant role in the jumping abilities of animals. For example, animals that live in open areas, like grasslands, may develop longer and more powerful legs to cover more ground quickly. In contrast, animals in dense forests might have shorter, more agile legs that allow for quick, short jumps to navigate through obstacles.
4. What role does jumping play in the survival of animals?
Ans.Jumping can be a critical survival mechanism for many animals. It helps them escape from predators, find food, or reach mates. For example, a rabbit's ability to jump quickly can help it evade a chasing fox. Additionally, jumping can also aid in territorial displays or courtship rituals, attracting mates through impressive leaps.
5. How do scientists study animal jumping and its mechanics?
Ans.Scientists study animal jumping through various methods, including high-speed cameras and motion analysis software. These tools allow researchers to capture the mechanics of jumping in detail, analyzing factors such as speed, angle, and force. By understanding these mechanics, scientists can gain insights into evolution, biomechanics, and the ecological roles of different species.
