NCERT solutions for Class 1 Maths Chapter 8 Fun with Numbers – complete answers & explanations
Learning numbers is an exciting journey for young students, and Class 1 Maths Chapter 8 Fun with Numbers makes this experience truly enjoyable. This chapter introduces children to the world of numbers beyond twenty, helping them understand counting, grouping, and number sequences up to 100 in a playful way. It is important because it builds a strong foundation for place value and basic arithmetic. This blog provides complete NCERT solutions strictly based on the worksheet to help students master these concepts with ease.
What this NCERT chapter covers?
1. Counting in groups: Learning how
to group items into tens and ones for easier counting.
2. Number sequences: Writing and identifying numbers from 21 to 100 in the correct order.
3. Tens frames: Using visual tools to represent numbers as groups of ten and extra ones.
4. Forwards and backwards counting: Practicing number flow in both directions to improve mental math.
5. Interactive activities: Using tools like the ginladi (number string) and games like slides and ladders to reinforce learning.
6. Observation skills: Identifying elements and counting them within complex pictures or traditional art like Warli paintings.
How to use these NCERT solutions?
1. Attempt first: Students should try
to solve the worksheet questions on their own to test their understanding.
2. Check for accuracy: Use these solutions to verify if the answers and counting are correct.
3. Guide the learning: Parents and teachers can use these explanations to help children understand the "why" behind grouping tens and ones.
4. Follow the flow: These solutions follow the exact order of the worksheet, making it easy to navigate alongside the study material.
Important tips & tricks for students
1. Focus on groups of ten: Always count how many full "tens" you have first; it makes counting large numbers much faster.
2. Use the ginladi: When placing number cards, look at the numbers right before and right after to find the perfect spot.
3. Avoid jumping numbers: While writing sequences like 31 to 50, double-check that you haven't skipped any digits.
4. Picture observation: When counting items in a picture, mark the ones you have already counted so you don't count them twice.
5. Practice backwards: Counting backwards from 50 or 100 helps you understand number relationships better.

In-text Exercises
Do you know how many oranges are there?
Each box can hold 10 oranges. In the picture, Simran has packed 3 boxes completely.
So, (10+10+10=30).
Therefore, the total number of oranges is 30.
Write 21 to 30
21, 22, 23, 24, 25, 26, 27, 28, 29, 30
Numbers 31 to 50
31, 32, 33, 34, 35, 36, 37, 38, 39, 40,
41, 42, 43, 44, 45, 46, 47, 48, 49, 50
Let us Do
A Explanation: Take a card with a number (for example, 27). Find the correct position on the ginladi (between 26 and 28) and clip the card there.
Sample Answer:
Number card chosen → 27
Placed between → 26 and 28
B Explanation: Look at the cards clipped on the ginladi and write the numbers in order.
Sample Answer:
21, 22, 23, 24, 25, 26, 27, 28, 29, 30
Count and write the numbers.
A: 44
B: 47
C: 32
Fill up the tens frames to show the number
Explanation: A tens frame is a box with 10 spaces. Each full frame represents one group of ten.
- For 29, fill 2 full tens frames (20) and then add 9 more ones in the next frame.
- For 30, fill 3 full tens frames (10+10+10=30).
- For 41, fill 4 full tens frames (40) and then add 1 more one in the next frame.
Answer:
29: Two tens and nine ones
30: Three tens and zero ones
41: Four tens and one one
Activity
Encourage children to count forwards and backwards using the ginladi.
- Forward counting sample: 21, 22, 23, 24, 25... up to 50.
- Backward counting sample: Start from 50 49, 48, 47, 46... down to 21.
Once children gain confidence, they can count without using the ginladi or number line.
Fill up the missing numbers.
34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46
Project Work
Explanation: Collect small items (like seeds, beads, buttons) and count how many can fit inside a matchbox.
Count and write the numbers from 51 to 60
51, 52, 53, 54, 55, 56, 57, 58, 59, 60
Count and write the numbers from 61 to 80
61, 62, 63, 64, 65, 66, 67, 68, 69, 70,
71, 72, 73, 74, 75, 76, 77, 78, 79, 80
Count and write the numbers from 81 to 100
81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100
Let us Do
Explanation: Tie a ginladi and attach number cards (1-99) at the correct places with clips. Play with friends by choosing random cards.
Activity
Explanation: Use ginladi to add numbers and find numbers between any two given numbers.
Count and write the numbers.
1: 47
2: 83
3: 66
Make a slide and ladder game by filling the missing numbers.
Fill the missing numbers in the grid sequentially from 1 to 100.
Activity
Explanation: This game is played outdoors by drawing squares with chalk. Movable sticks and ropes are used as ladders and slides. Children place number cards in the squares from 1 to 100. Some task cards can be added to make the game more fun. Instructions can be modified, such as:
- Jump to a number where the digits are exchanged
- Skip one number on your right and jump
- Move forward or backward by 2 steps
Sample Answer:
- If the task card says "jump to a number where the digits are exchanged" and you are on 12, you must jump to 21.
- If the task card says "skip one number on your right and jump" and you are on 35, you skip 36 and jump to 37.
- If the task card says "move backward by 2 steps" and you are on 50, you go back to 48.
Look at the picture
Observe the picture carefully and observe each element carefully.

A: Sample Answer: People are dancing and working.
B: Houses, trees, animals, people, sun, hen, dog, cart, grass, honeycomb, honeybee etc.
C: 1 house.
D: 10 people.
E: 10-11 lines.
