NCERT Class 4 Mathematics Math-Mela: Chapter 9 — Equal Groups
This chapter, "Equal Groups," from the NCERT Class 4 Mathematics textbook "Math-Mela," introduces the concept of multiples through animal jumping scenarios. Students learn to identify numbers touched by animals jumping in fixed steps, such as a frog jumping 3 steps at a time. The chapter explores multiples of 3, 4, 6, and 8, using examples like squirrels, rabbits, and kangaroos. It poses questions about reaching specific numbers, the number of jumps required, and identifying common numbers touched by different animals. Students are encouraged to observe patterns and share their thoughts, reinforcing the understanding of multiplication and multiples as a foundation for future mathematical concepts. This chapter helps students grasp skip counting and its relation to multiplication tables, crucial for CBSE curriculum progression.

Practice questions
- The frog jumps 3 steps at a time. Which numbers will it touch? Answer: Multiples of 3 (e.g., 0, 3, 6, 9...).
- The squirrel jumps 4 steps at a time. How many times should it jump to reach 60? Answer: 15 times (60 / 4 = 15).
- What is the smallest 3-digit number the rabbit will touch if it jumps 6 steps at a time? Answer: 102 (since 100/6 is approx 16.67, the next multiple is 6*17=102).
- To reach 48, how many times did the rabbit jump (6 steps at a time)? Answer: 8 times (48 / 6 = 8).
- To reach 48, how many times did the kangaroo jump (8 steps at a time)? Answer: 6 times (48 / 8 = 6).
Frequently asked questions
What is the main concept taught in NCERT Class 4 Mathematics Chapter 1?
The chapter "Equal Groups" primarily teaches the concept of multiples and skip counting through real-life examples of animals jumping.
How does the chapter explain multiples?
Multiples are explained by showing the numbers an animal touches when it jumps a fixed number of steps repeatedly, like a frog jumping 3 steps at a time.
Can a frog touch the number 67 if it jumps 3 steps at a time?
No, the frog cannot touch 67 because 67 is not a multiple of 3 (67 divided by 3 leaves a remainder).
What does it mean for the squirrel to jump 4 steps at a time?
It means the squirrel lands on numbers that are multiples of 4 (0, 4, 8, 12, and so on).
How many jumps does the rabbit need to reach 48 if it jumps 6 steps at a time?
The rabbit needs 8 jumps to reach 48, as 48 divided by 6 equals 8.
What is the smallest 3-digit number the rabbit will land on?
The smallest 3-digit number the rabbit will land on is 102, as it is the first multiple of 6 that is greater than or equal to 100.
