Knowing Our Numbers | Maths quiz questions for class 6
If you ask a Class 6 student what maths feels like, you’ll probably hear two kinds of answers. Some will say, “It’s fun!” Others might quietly whisper, “It’s confusing…” And honestly, both are fair. But when we begin with something simple and friendly like Knowing Our Numbers, maths slowly turns from scary to surprisingly satisfying.
Knowing Our Numbers is not just a chapter in the Class 6 syllabus. It’s the foundation. It’s where students truly understand what numbers mean, how big they can grow, how we compare them, and how we use them in real life without even thinking about it.
Before algebra, before complicated formulas, before long equations… There are numbers. Plain, powerful numbers.
So let’s talk about it in a way that feels less like a textbook and more like a real conversation.
Why “Knowing Our Numbers” Matters
Imagine trying to build a house without knowing bricks exist. Sounds impossible, right? That’s what higher maths feels like without a proper understanding of numbers.
In Class 6, students move beyond small numbers and enter the world of large numbers — thousands, lakhs, millions, crores. Suddenly, numbers aren’t just 245 or 879 anymore. They become 7,56,43,210. And reading them correctly becomes important.
This chapter helps students:
• Read large numbers
• Write numbers in words
• Understand place value
• Compare numbers
• Arrange them in ascending or descending order
• Estimate sums and differences
• Understand Roman numerals
It sounds simple. But this is where clarity begins.
Now, instead of just explaining concepts, let’s explore some quiz-style questions because quizzes make learning feel like a game, not a burden.
Section 1: Understanding Large Numbers
Let’s warm up.
1. Write the number name for 7,45,32,109.
Take a moment. Break it into parts. Crores, lakhs, thousands, hundreds.
Answer: Seven crore forty-five lakh thirty-two thousand one hundred nine.
See? When you separate into periods, it becomes manageable.
2. Write 9 crore 4 lakh 6 thousand 12 in numerals.
Think carefully. Don’t rush.
9,04,06,012
Small mistakes happen here. Students often forget zeroes. That’s okay. Zero is quiet, but powerful.
Section 2: Place Value Magic
Place value is like assigning roles in a play. Each digit has a position. And that position gives it power.
3. What is the place value of 5 in 3,57,48,291?
The digit 5 is in the ten lakh place.
So its place value = 50,00,000.
It’s interesting, right? That same 5 could mean just five… or fifty lakhs. Position changes everything.
4. Find the difference between the place value and face value of 8 in 6,18,24,870.
Face value is simply 8.
Place value is 800 (since it is in the hundreds place).
Difference = 800 – 8 = 792.
This question looks tricky at first. But once you remember that face value never changes, it becomes easy.
Section 3: Comparing Numbers
Comparing numbers is something we do daily. Whose marks are higher? Which city has a bigger population?
5. Arrange in ascending order:
4,32,109
4,23,901
4,32,019
4,03,219
Start comparing from left.
Ascending order:
4,03,219
4,23,901
4,32,019
4,32,109
The trick? Look at the digits from left to right. First difference decides.
Section 4: Estimation – Not Exact, But Smart
Life doesn’t always need exact answers. Sometimes we estimate.
If a shopkeeper says something costs ₹4,98,499, you might quickly think, “Okay, around five lakhs.”
That’s an estimation.
6. Round off 7,84,213 to the nearest thousand.
Look at the hundreds digit. It’s 2 (less than 5).
So answer = 7,84,000.
7. Round off 3,49,856 to the nearest ten thousand.
Check the thousands digit (9). It is more than 5.
So round up.
Answer = 3,50,000.
Estimation saves time. And in competitive exams later, this skill becomes gold.
Section 5: Roman Numerals – A Little History
Roman numerals feel like secret codes.
I = 1
V = 5
X = 10
L = 50
C = 100
D = 500
M = 1000
8. Write 84 in Roman numerals.
80 = LXXX
4 = IV
So, 84 = LXXXIV
9. Write the Hindu-Arabic number for XCIX.
XC = 90
IX = 9
So, XCIX = 99.
Roman numerals are fun once you understand the subtract rule.
Section 6: Real-Life Thinking Questions
Now let’s make it practical.
10. The population of a town is 8,79,54,321. Write it in words in the International System.
In the international system, we write:
87,954,321
Eighty-seven million nine hundred fifty-four thousand three hundred twenty-one.
See how grouping changes? Both the Indian system and the International system both matter.
Small Mistakes Students Make (And It’s Okay)
• Forgetting commas in the correct places
• Missing zeroes
• Confusing lakh and million
• Rounding incorrectly
• Writing wrong number names
These aren’t failures. They’re just steps in learning. Maths improves with practice, not pressure.
A Quick Mini Quiz Challenge
Try solving these without looking at the answers:
- Which is greater: 6,54,32,109 or 6,45,99,999?
- Write the predecessor of 1,00,00,000.
- Write the successor of 9,99,999.
- Round off 45,67,891 to the nearest lakh.
- Write 2026 in Roman numerals.
Answers:
- 6,54,32,109
- 99,99,999
- 10,00,000
- 46,00,000
- MMXXVI
How many did you get right? Even 3 out of 5 is good. Improvement matters more than perfection.
Why Practice Through Quizzes Works
When students solve quiz questions:
• They think actively
• They make mistakes and correct them
• They remember better
• They gain confidence
Reading theory is fine. But solving questions builds real understanding.
And honestly, maths becomes enjoyable when it feels like solving puzzles.
Final Thoughts
Knowing Our Numbers is not just Chapter 1 in Class 6 Maths. It’s the doorway to everything ahead — algebra, geometry, mensuration, data handling… all of it.
If the basics are strong, the future feels lighter.
So instead of memorising blindly, play with numbers. Compare them. Break them. Round them. Write them in words. Convert them.
Numbers are everywhere — in mobile bills, cricket scores, population counts, bank balances, and even YouTube views.
Once students truly “know” numbers, maths stops being scary.
It becomes logical. Predictable. Even fun.
And maybe… just maybe… the next time someone asks a Class 6 student about maths, they’ll smile a little before answering.
