NCERT Solutions for Class 1 Maths Chapter 04 Making 10

Question A. Write the number of dots on each bug.
Answer:
The number of dots on each ladybug is:
* Top-left ladybug has 4 dots.
* Top-right ladybug has 5 dots.
* Bottom-left ladybug has 6 dots.
* Bottom-right ladybug has 3 dots.
In simple words: We count the small black dots on the back of each red ladybug.

Exam Tip: Point to each dot with your pencil to count them one by one without skipping any.

Question B. Make some dot designs with objects like tamarind seeds, pebbles, buttons, bindis, etc., and identify the number of dots in each arrangement.
Answer:
This is a fun craft activity. You can make beautiful shapes (like butterflies, snowflakes, or bugs) using small objects like:
* Colorful buttons
* Small pebbles or stones
* Smooth seeds
* Brightly colored bindis
Count how many seeds or buttons you use in each of your designs.
In simple words: Collect small stones or buttons to make pretty shapes, then count them.

Exam Tip: Arranging buttons in rows of 2 or 5 makes it easier to count them quickly.

Question C. Identify and write the numbers formed by the arrangement of the red bindis
Answer:
The numbers formed by the group of red bindis are:
* The first group shows the number 5.
* The second group shows the number 3.
* The third group shows the number 4.
In simple words: We count the red spots on the paper to find the numbers 5, 3, and 4.

Exam Tip: Recognizing standard dot patterns (like on a dice) helps you know the number instantly without counting.

Question D. Play with your friend. Roll the dice and colour a box with the same number of dots as on the dice. Take turns with your friend and roll again. The child with more number of coloured boxes will win.
Answer:
This is a 2-player board game. Take turns rolling a die and coloring a square on the grid that has the matching number of dots:
* My final score: 55 boxes colored.
* Friend's final score: 47 boxes colored.
* Result: I won the game because I colored more boxes.
In simple words: Roll a die, find a box with that many dots, and color it. The person with the most colored boxes wins!

Exam Tip: Keep your coloring neat and count your final colored boxes carefully to see who won.

Question G. Gola monkey wears his favourite shirt with four buttons. He went to the garden and ate too many bananas as he was fond of them. What do you think happened then? One of the buttons popped out and rolled away. But he cannot dream of giving up bananas and he keeps on losing all the buttons one by one. Write the number of buttons.
Answer:
The number of buttons left on Gola's shirt as they pop off one by one:
* At first, Gola has 4 buttons.
* After eating, he has 3 buttons left.
* Next, he has 2 buttons left.
* Then, only 1 button is left.
* At the end, he has 0 buttons left.
In simple words: As the monkey's tummy grows, his shirt buttons pop off from four down to zero.

Exam Tip: Subtracting exactly 1 from a number is like counting backwards (4, 3, 2, 1, 0).

Question. Write the number of birds sitting on the branch of the tree.
Answer:
We count the birds on the branch in each picture:
* First branch has 3 birds.
* Second branch has 2 birds.
* Third branch has 1 bird.
* Fourth branch has 0 birds.
In simple words: The birds fly away one by one, leaving three, then two, then one, and finally zero birds on the branch.

Exam Tip: When there are no objects or birds left to count, we write the number "0" (zero).

Question. Write '0'
Answer:
Trace and write the digit 0 in your grid cells to practice writing zero.
In simple words: We draw a round oval shape to write the number zero.

Exam Tip: Keep your zeros neat and rounded like an egg, and make sure they touch the bottom line of the box.

Question. Think and Tell
A. How many suns do you see in the night?
B. How many moons do you see at noon?
Answer:
A. We see 0 suns in the night sky.
B. We see 0 moons at noon.
In simple words: The sun does not shine at night, and the moon does not shine at midday, so the answer is zero.

Exam Tip: Zero is used to describe things that are completely absent or not there.

Question. Tenth Birthday
It is Aastha's tenth birthday. Her father prepared halwa for her. She is celebrating the birthday with her friends. I am 9 years old and after 1 more year, I will be 10 years old. So, 9 and 1 more makes 10. She has lighted diyas on her birthday. Count and write the number of objects.
Answer:
Counting the items for Aastha's birthday celebration:
* Aastha lights 10 diyas on her table.
* The girl wears a necklace with 10 beads.
* The boy holds a plate containing 10 sweet laddoos.
* The box has 10 colorful crayons.
* The girl holds a bunch of 10 bananas.
* The boy holds a branch with 10 green leaves.
In simple words: Everything at the birthday party is grouped in tens: 10 diyas, 10 laddoos, 10 crayons, 10 bananas, and 10 leaves.

Exam Tip: Ten (10) is a very important number in math. It is made by adding 1 to 9 (9 + 1 = 10).

Question A. Count and draw beads to make a string of 10 beads.
i.
ii.
iii.
iv.
Answer:
To make each string have exactly 10 beads:
* String i: There are 8 beads already. We need to draw 2 more beads. (8 + 2 = 10)
* String ii: There are 7 beads already. We need to draw 3 more beads. (7 + 3 = 10)
* String iii: There are 5 beads already. We need to draw 5 more beads. (5 + 5 = 10)
* String iv: There are 2 beads already. We need to draw 8 more beads. (2 + 8 = 10)
In simple words: We count the beads already on the string and add more until we have exactly ten.

Exam Tip: You can find the missing number of beads by counting up from the starting number to 10.

Question B. Draw buttons to make a ten frame of buttons.
i.
ii.
iii.
iv.
Answer:
To fill each ten-frame completely with 10 buttons:
* Frame i: Has 3 buttons. We draw 7 more buttons to fill the frame. (3 + 7 = 10)
* Frame ii: Has 6 buttons. We draw 4 more buttons to fill the frame. (6 + 4 = 10)
* Frame iii: Has 2 buttons. We draw 8 more buttons to fill the frame. (2 + 8 = 10)
* Frame iv: Has 1 button. We draw 9 more buttons to fill the frame. (1 + 9 = 10)
In simple words: We fill all the empty squares in each grid with buttons so there are exactly ten buttons in each frame.

Exam Tip: A ten-frame has 10 spaces. Counting the empty boxes tells you exactly how many buttons you need to draw.

Question. The Handy Five and Ten - Follow the pattern and write the number pairs separated by the stick.
Answer:
Following the pattern of 5 objects divided by a stick:
* First row: 1 and 4
* Second row: 2 and 3
* Third row: 3 and 2
* Fourth row: 4 and 1
* Fifth row: 5 and 0
In simple words: We look at how many seeds are on the left and right of the stick. Together they always add up to five.

Exam Tip: These pairs (1 and 4, 2 and 3, etc.) are called "number partners" for 5.

Question. Number Pairs of 10 - Follow the pattern and write the number pairs separated by the stick.
Answer:
The number pairs of fingers that add up to 10 are:
* Row 1: 1 and 9 make 10.
* Row 2: 2 and 8 make 10.
* Row 3: 3 and 7 make 10.
* Row 4: 4 and 6 make 10.
* Row 5: 5 and 5 make 10.
In simple words: We count the fingers shown on each hand. When we put them together, they always make ten.

Exam Tip: Learning these pairs helps you add up to 10 very quickly in your head.

Question. Number Cards (Sets of 0 to 10) - Keep all cards face down. One child picks up a card and keeps it face up. The other child picks up another card and keeps it face up. If the pair of cards make 10 then the second student takes both the cards. And the turn goes back to the first student who will pick up another card. Match the cards to make 10.
Answer:
In this card game, we match pairs of cards to make a total of 10. The correct pairs are:
* Ace (1) and 9 (1 + 9 = 10)
* 2 and 8 (2 + 8 = 10)
* 6 and 4 (6 + 4 = 10)
* 7 and 3 (7 + 3 = 10)
* 5 and 5 (5 + 5 = 10)
In simple words: To win the card pairs, pick two cards whose numbers add up to exactly ten.

Exam Tip: An Ace card counts as 1. Match it with a 9 to make 10!

Question. Write the numbers 11-20.
Answer:
The completed number grid from 11 to 20 should be written in rows as follows:
11, 12, 13, 14, 15, 16, 17, 18, 19, 20
In simple words: We fill in all the empty boxes with the correct numbers from 11 up to 20.

Exam Tip: Practice tracing the numbers carefully to learn how to write two-digit numbers correctly.

Question. Count and Write - A. Count and write the answers.
Answer:
Counting the items in the boxes:
* There is 1 bundle of 10 sticks and 8 loose sticks, making 18 sticks in total.
* There is 1 large leaf branch of 10 leaves and 3 loose leaves, making 13 leaves in total.
In simple words: One group of ten plus eight more is 18. One group of ten plus three more is 13.

Exam Tip: A tied bundle always represents "10". Just add the single loose items to 10 to find the total quickly.

Question B. Colour the tens frames to show the number.
14, 19, 16
Answer:
To show these numbers on the double ten-frames:
* For 14: Color 1 full frame (10 boxes) and 4 boxes in the second frame.
* For 19: Color 1 full frame (10 boxes) and 9 boxes in the second frame.
* For 16: Color 1 full frame (10 boxes) and 6 boxes in the second frame.
In simple words: For any teen number, we color one full grid of ten, and then color the leftover amount in the second grid.

Exam Tip: Teen numbers are made of "one ten" and some "ones". 14 is 10 and 4.

Question C. Write down the numbers in sequence.
Answer:
Following the winding snake path from 1 to 20, the missing numbers are:
* Row 1 (moving right): 1, 2, 3, 4
* Row 2 (moving left): 8, 7, 6, 5
* Row 3 (moving right): 9, 10, 11, 12
* Row 4 (moving left): 16, 15, 14, 13
* Row 5 (moving right): 17, 18, 19, 20
In simple words: We write the numbers from 1 to 20 along a winding path, following the direction of the arrows.

Exam Tip: Pay close attention to the arrow direction in snake grids, as the numbers switch between moving left and right.

Question D. Encircle a group of ten in the pictures and match with the number.
Answer:
First, count and circle a group of exactly 10 items, then count the total and match:
* Row 1 (Flowers): Circle 10 flowers. The total is 17 flowers, so connect to 17.
* Row 2 (Beads): Circle 10 beads. The total is 16 beads, so connect to 16.
* Row 3 (Buttons): Circle 10 buttons. The total is 20 buttons, so connect to 20.
* Row 4 (Leaves): Circle 10 leaves. The total is 10 leaves, so connect to 10.
In simple words: Draw a circle around ten items first, then count the rest to match with the correct total number.

Exam Tip: Grouping by ten makes it much easier to count large quantities of objects.

Question E. A group of friends while playing built some towers. i. Tick the tallest tower. ii. Which tower used the most number of blocks? Write the number of blocks used in. iii. Which tower used the least number of blocks? Write the number of blocks used in.
Answer:
Analyzing the blocks in the children's towers:
* i. Tallest Tower: The second tower from the left is the tallest. We put a tick under it.
* ii. Most Blocks: The tallest tower has the most blocks, which is 9 blocks.
* iii. Least Blocks: The third tower from the left has the least blocks, which is 4 blocks.
In simple words: The tallest tower uses nine blocks. The shortest tower uses only four blocks.

Exam Tip: The tower with the highest height usually has the most blocks, while the shortest tower has the least.
