NCERT Solutions for Class 1 Maths Chapter 13 So Many Toys

Question 1. Look at the picture and find the number of different toys. Complete the following sentences by using more than/less than/equal to. A. The number of dolls is ________ the number of cars. B. The number of elephants is ________ the number of dolls. C. The number of teddy bears is ________ the number of elephants. D. The number of cars is ________ the number of teddy bears.
Answer:
Let's find the count of each toy from the shelf:
* Elephants: 4
* Teddy Bears: 3
* Cars: 1
* Dolls: 5

Comparing the toy counts:
* A. The number of dolls (5) is more than the number of cars (1).
* B. The number of elephants (4) is less than the number of dolls (5).
* C. The number of teddy bears (3) is less than the number of elephants (4).
* D. The number of cars (1) is less than the number of teddy bears (3).
In simple words: We count the toys on the shelves and use "more than" or "less than" to compare their counts.

Exam Tip: If the first number is bigger, use "more than"; if it is smaller, use "less than".

Question 2. Colourful Flowers - Name the colour of the flowers which you see mostly in a garden. Look at the picture of colourful flowers and write the number of flowers. Blue flowers [ ], Orange flowers [ ], Red flowers [ ], Purple flowers [ ] A. Name the colour of flowers which are least in number. B. Name the colour of the flowers which are most in number. True or False - A. Number of red flowers is more than the blue flowers. [ ] B. Number of orange flowers is less than the purple flowers. [ ]
Answer:
* Favorite Garden Flowers: Red and rose-colored flowers are most commonly found in gardens.
* Flower Counts:
- Blue flowers: 5
- Orange flowers: 4
- Red flowers: 9
- Purple flowers: 6
* Questions:
- A. The flowers that are least in number are the Orange flowers (only 4).
- B. The flowers that are most in number are the Red flowers (a total of 9).
* True or False:
- A. The number of red flowers is greater than the blue flowers: True (9 is more than 5).
- B. The number of orange flowers is less than the purple flowers: True (4 is less than 6).
In simple words: We count each group of colorful flowers to see which ones are the most (red) and which ones are the least (orange).

Exam Tip: "Most in number" refers to the group with the highest count, while "least in number" refers to the lowest count.

Question 3. Solve the following puzzles: A. Kopal arranged number cards in the below image and Anaya hide them with bowls as shown. Can you recognise the numbers? B. Count the number of logs. Is it 3 logs or 4 logs? C. This is how Zarina set the glasses. Help her in extending the arrangement.
Answer:
* A. Hidden Numbers: The hidden numbers on the cards under the blue bowls are 2, 3, 8, 9, 0, 5, and 4.
* B. Counting Logs: There are exactly 4 logs on the grass.
* C. Extending Glass Towers: Zarina's pattern increases the base of the triangle of cups by 1 each time:
- Tower 1 has 1 cup (1)
- Tower 2 has 3 cups (1 + 2)
- Tower 3 has 6 cups (1 + 2 + 3)
- Tower 4 will have 10 cups (1 + 2 + 3 + 4)
- Tower 5 will have 15 cups (1 + 2 + 3 + 4 + 5)
In simple words: We can identify hidden numbers, count overlapping logs (4), and grow a triangular pyramid pattern of glasses step-by-step.

Exam Tip: Triangular numbers like 1, 3, 6, 10, 15 are formed by adding successive counting numbers (1, +2, +3, +4, +5).

Question 4. Solve the following activities: D. Find the numbers from 1 to 10. E. Fill the numbers from 1 to 5 in the given balls so that the sum on both sides is equal. F. What is the maximum number of kids that can share the pieces of pizza separately?
Answer:
* D. Word Search Solutions: The number names hidden in the grid are: one, two, three, four, five, six, seven, eight, nine, and ten.
* E. Equal Sum Triangle: To make both sides equal, place the numbers 1 to 5 in the balls as follows:
- Place 3 in the top-most ball.
- On the left side, place 1 and 5 (Sum: 3 + 1 + 5 = 9).
- On the right side, place 2 and 4 (Sum: 3 + 2 + 4 = 9).
* F. Questions for Gillu (Answer = 8): We can ask the following questions to make Gillu happy:
- "What is 10 minus 2?" (10 - 2 = 8)
- "How many legs does an octopus have?" (8 legs)
- "What is the maximum number of kids that can share this 8-sliced pizza separately?" (8 children)
In simple words: We can solve number puzzles, place numbers in a triangle to get the same sum (9) on both sides, and ask fun riddles whose answer is always eight.

Exam Tip: For equal-sum triangles, putting the middle-value number (like 3) at the top vertex helps balance the other numbers easily.

Question 5. Solve the following grid and mirror puzzles: G. Fill ▲, [square icon] and ○ in the boxes in such a way that any shape occurs only once in a row (horizontal) and column (standing). H. Take 4 different objects (each object should be 4), such as 4 buttons, 4 pebbles, 4 seeds, 4 clay balls, etc. Now place them in the given boxes in such a way that every object occurs only once in a row (horizontal) and a column (vertical standing). I. Who am I? (A mirror can help you.)
Answer:
* G. Shape Sudoku (3x3): The completed grid where no shape repeats in any row or column:
- Row 1: Triangle, Circle, Square
- Row 2: Circle, Square, Triangle
- Row 3: Square, Triangle, Circle
* H. Object Sudoku (4x4): Arrange the 4 different items (Star button, Pebble, Bean seed, Orange ball) so that each appears exactly once in every row and column. One correct arrangement is shown in the completed grid.
* I. Mirror Numbers: When we hold the cards in front of a mirror, we can read the correct numbers:
- First row: 25 and 73
- Second row: 52 and 39
In simple words: We can solve shape and object puzzles without repeating items, and read backwards numbers easily using a mirror.

Exam Tip: For grid puzzles (Sudoku), always check both horizontally (rows) and vertically (columns) to make sure no item is repeated.

Question 6. Solve the puzzles: J. Who am I? K. Six matchsticks are used to make a zero. Can you make any other number by shifting a single matchstick? L. Find out the missing piece and complete the pot.
Answer:
* J. Number Riddles (Who am I?):
- i. I am between 5 and 10, and become three more when turned upside down: 6 (6 becomes 9).
- ii. I am 3 more than 8 and 3 less than 14: 11 (8 + 3 = 11, and 14 - 3 = 11).
- iii. I am after 50 and before 54, and my digits add up to 7: 52 (since 5 + 2 = 7).
- iv. I am just before 40: 39.
- v. Add 5 to me to get 24: 19 (19 + 5 = 24).
- vi. I am just after 35: 36.
- vii. Reduce 8 from me and 14 is left: 22 (since 22 - 8 = 14).
* K. Matchstick Puzzle: By moving only one matchstick from the top-right of the zero to the middle, we can change the '0' into a 6 (or a 9).
* L. Completed Pot: The correct missing piece of the clay pot is the one that matches the blue floral border pattern perfectly, which is the piece shown on the right.
In simple words: We solve fun number riddles, change a matchstick '0' into a '6', and find the matching puzzle piece to repair the pot.

Exam Tip: Read word puzzles slowly and convert them into simple math equations (like [ ] + 5 = 24) to find the answer easily.

Question 7. Solve the puzzles: M. How many times can you subtract 5 from 25? N. Ranu has 3 seeds. She wants to place them on any 3 numbers of the given chart in such a way that the sum of those numbers will be 17. Can you help Ranu in finding the numbers. O. Encircle the identical shadow image.
Answer:
* M. Subtracting 5 from 25: You can subtract 5 from 25 exactly 5 times until you reach 0:
1. 25 - 5 = 20
2. 20 - 5 = 15
3. 15 - 5 = 10
4. 10 - 5 = 5
5. 5 - 5 = 0
* N. Placing Seeds to make 17:
- With 3 seeds: Some of the correct 3-number combinations are: 7 + 8 + 2 = 17, or 9 + 7 + 1 = 17.
- With 2 seeds: To get a total of 17, we can place them on any of these pairs: 15 and 2 (since 15 + 2 = 17), 16 and 1 (since 16 + 1 = 17), 17 and 0 (since 17 + 0 = 17), or 12 and 5 (since 12 + 5 = 17).
* O. Monkey Shadow: Shadow ii is the exact matching shadow of the cute monkey on the left.
In simple words: We can take away 5 from 25 five times. We can also combine two or three numbers on the grid to add up to 17, and find the correct shadow of the monkey.

Exam Tip: To find matching shadows, compare key details like the direction of the tail, ears, and hands carefully.

Question 8. Solve the puzzles: P. Write numbers from 5 to 9 in the card given below such that the row and the column have the same total. Q. Try to get the center number by doing addition or subtraction. R. Write down the correct numbers in the.
Answer:
* P. Number Cross (5 to 9): Arrange the numbers 5, 6, 7, 8, and 9 so both directions add up to 20:
- Horizontal row: 8, 5, 7
- Vertical column: 9, 5, 6
* Q. Hexagon Targets:
- To make 11: 10 + 1 = 11, 16 - 5 = 11, 8 + 3 = 11, 12 - 1 = 11, 9 + 2 = 11, 15 - 4 = 11.
- To make 15: 16 - 1 = 15, 8 + 7 = 15, 17 - 2 = 15, 10 + 5 = 15, 20 - 5 = 15, 9 + 6 = 15.
* R. Chained Circles (Target Sum = 15): The correct numbers to fill in the blank circles around the central sum of 15 are:
- 12 (at the top, because 12 + 3 = 15)
- 7 (top-left, because 7 + 8 = 15)
- 13 (middle-left, because 13 + 2 = 15)
- 8 (bottom-left, because 8 + 7 = 15)
- 6 (at the bottom, because 6 + 9 = 15)
- 11 (bottom-right, because 11 + 4 = 15)
- 5 (middle-right, because 10 + 5 = 15)
- 9 (top-right, because 9 + 6 = 15)
In simple words: We solve different addition and subtraction puzzles so that all connected rows, columns, and circles add up to the correct target numbers (11, 15, or 20).

Exam Tip: Focus on the target number in the center of the wheel or cross first, then work out the missing numbers by using simple addition or subtraction.

Question 9. Solve the puzzles: S. Sarita has four coins of different values. What is the minimum number of coins used to spend exactly Rs. 49? T. Find out the value of orange. U. Let us play the ball game.
Answer:
* S. Paying Rs. 49 with Minimum Coins: The minimum number of coins needed is 7 coins: four Rs. 10 coins, one Rs. 5 coin, and two Rs. 2 coins. (10 + 10 + 10 + 10 + 5 + 2 + 2 = Rs. 49).
* T. Value of the Orange: If two watermelons equal 8, then one watermelon is worth 4 (since 4 + 4 = 8). Since an orange plus a watermelon equals 10, the orange must be worth 6 (since 6 + 4 = 10).
* U. Ball Game (Balls: 2, 4, 6, 8):
- i. Choose 3 balls to make 15: Not Possible (all ball numbers are even, and adding three even numbers always gives an even sum, so we can never make 15).
- ii. Maximum score with 3 balls: 4 + 6 + 8 = 18.
- iii. Minimum score with 3 balls: 2 + 4 + 6 = 12.
In simple words: We calculate money combinations with the fewest coins (7), find the value of an orange (6), and solve a fun ball-adding puzzle.

Exam Tip: Remember that adding three even numbers always results in an even number. This is why making an odd number like 15 is impossible!
