NUMBERS CAN TELL US
THINGS
Imagine students lined up for a race. Each
student says a number to show how many of
the runners next to them are faster.
A student says '1' if there is one faster runner next to them.
A student says '2' if there are two faster runners next to
them.
A student says '0' if there are no faster runners next to
them.
Each number shows how many of their neighbors are faster.

Read MoreFAQs on PPT: Number Play
| 1. What are factors and multiples and how do I tell them apart? |  |
Ans. Factors are numbers that divide evenly into another number with no remainder, while multiples are the results you get when multiplying a number by whole numbers. For example, 3 is a factor of 12, but 12 is a multiple of 3. Understanding this distinction helps students solve divisibility problems and recognize number patterns in Class 6 Mathematics effectively.
| 2. How do prime numbers and composite numbers differ in number play? | |
Ans. Prime numbers have exactly two factors-1 and themselves-like 2, 3, 5, and 7. Composite numbers have more than two factors, such as 4, 6, 8, and 9. The number 1 is neither prime nor composite. Recognizing these classifications is essential for solving problems involving number classification and mathematical reasoning in Class 6.
| 3. What's the easiest way to find HCF and LCM using prime factorisation? | |
Ans. Prime factorisation breaks numbers into their prime number components. For HCF (Highest Common Factor), multiply the common prime factors with their lowest powers. For LCM (Lowest Common Multiple), multiply all prime factors with their highest powers. This systematic approach simplifies finding HCF and LCM compared to listing methods and strengthens number theory skills.
| 4. Why do some numbers have so many divisors and others have just a few? | |
Ans. Numbers with many divisors typically have more prime factors or higher powers of primes. For example, 12 (2² × 3) has six divisors, while 7 (prime) has only two. This relates directly to prime factorisation patterns in number play. Understanding divisor count helps students grasp deeper number relationships and recognize composite number behaviour intuitively.
| 5. How can I quickly check if a big number is divisible without doing long division? | |
Ans. Divisibility rules provide shortcuts: numbers ending in 0 or 5 are divisible by 5; even numbers divide by 2; sums of digits divisible by 3 mean the number is too. These rules for 2, 3, 4, 5, 6, 8, 9, and 10 save calculation time during problem-solving. Mastering divisibility rules strengthens mental arithmetic and number sense in Class 6 Mathematics significantly.
