Chapter 13 of Class 5 Maths Mela, Animal Jumps, uses frog and kangaroo jumping scenarios to teach skip counting, factors, multiples, and prime and composite numbers.
Key Concepts
Factors: numbers that divide exactly into another number, e.g. the factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24.
Multiples: the results of multiplying a number by 1, 2, 3, and so on.
Prime and composite numbers: a prime number has exactly two factors (1 and itself), like 2, 3, 5, 7; a composite number has more than two factors.
Quick Recap
- If a frog jumps 3 units and a kangaroo jumps 12 units, 4 frog jumps equal 1 kangaroo jump (12 ÷ 3 = 4).
- Writing full fact families for a multiplication fact reinforces how factors and multiples connect.
Common Mistake to Avoid
Forgetting that 1 is neither prime nor composite — it has only one factor (itself), so it doesn’t fit either definition.
Frequently Asked Questions
What is the difference between a factor and a multiple?
A factor divides exactly into a number; a multiple is what you get by multiplying a number by a whole number.
How do you check if a number is prime?
Test whether it can be divided exactly by any number other than 1 and itself — if not, it’s prime.
