Chapter 13: So Many Toys

Introduction

"So Many Toys" is the last chapter of Joyful Mathematics for Class 1. It has two parts. In the first, children count and compare things in a picture – toys and colourful flowers – using more than, less than and equal to, which is the beginning of data handling. The second part is a set of puzzles that use everything learnt this year: numbers, patterns, adding, subtracting, shapes and money.

What's in this Chapter

Toys: Count elephants, teddy bears, cars and dolls in a picture, then complete sentences with more than / less than / equal to, e.g., "The number of dolls is ___ the number of cars."

Colourful Flowers: Count blue, orange, red and purple flowers; name the colour that is least and most in number; answer true or false questions.

Project Work: Make a card with a border of flowers; find how many children in the class have 3 letters, 4 letters or more than 4 letters in their names.

Puzzles:

- Hidden number cards under bowls; count logs (3 or 4?); extend Zarina's arrangement of glasses.

- A word search to find number names from one to ten.

- Fill 1 to 5 in balls so both sides have equal sums.

- Gillu likes the number 8 – ask questions whose answer is 8.

- Fill shapes (and later 4 kinds of objects) so that each occurs only once in every row and column.

- Mirror numbers: "Who am I?" with 52, 37, 25 and 93.

- Who am I? riddles: between 5 and 10 and becoming three more when read upside down (6, which becomes 9); 3 more than 8 and 3 less than 14 (11); after 50 and before 54 with digits adding to 7 (52); just before 40 (39); add 5 to get 24 (19); just after 35 (36); reduce 8 and 14 is left (22).

- Shift one matchstick of a six-stick zero to make another number.

- How many times can you subtract 5 from 25? (5 times)

- Ranu places 3 seeds on numbers in a chart so that they add to 17; with 2 seeds, find two numbers making 17.

- Find identical shadows, fill 5 to 9 so row and column totals are equal, and find the value of hidden fruits in picture sums.

- Sarita has four coins of different values – what is the fewest coins to pay exactly ₹49?

- A ball game: choose 3 balls with a sum of 15, the maximum and the minimum score.

Key Ideas

Counting and comparing groups helps us answer questions about information (data).

More than, less than, equal to compare two numbers.

Most and least tell which group is biggest or smallest.

Puzzles need careful thinking and checking; there may be more than one answer.

Many puzzles use addition and subtraction facts learnt earlier.

Activities from the Book

Count toys and flowers and complete comparison sentences.

Survey the class for name lengths.

Play the hidden-number game using hands to cover cards.

Try the row–column puzzles with buttons, pebbles, seeds and clay balls.

Words to Learn

more than – bigger in number (से अधिक)

less than – smaller in number (से कम)

equal to – the same number (के बराबर)

most / least – the biggest / smallest number (सबसे अधिक / सबसे कम)

true / false – right / wrong (सही / गलत)

puzzle – a problem to think about (पहेली)

row – a line going across (पंक्ति)

column – a line going up and down (स्तंभ)

riddle – a question with a hidden answer (पहेली / बूझो तो जानें)

Tips for Parents & Teachers

Count toys at home by type and ask "Which do you have most of?"

Make a simple class survey, such as favourite fruits, and compare numbers.

Enjoy the puzzles together; praise good reasoning, not just the correct answer.

Let children make their own "Who am I?" riddles.

Keep the mirror and matchstick puzzles hands-on with real objects.

Common Mistakes

Deciding which group is bigger by how much space it takes, not by counting.

Mixing up rows (across) and columns (up and down).

Giving up on a puzzle after one try; encourage trying another way.

💡 Key Learning Points

✓Count and compare groups using more than, less than and equal to.
✓Find which group is most and least in number.
✓Collect simple information by counting, e.g., letters in names.
✓Solve number riddles using addition and subtraction.
✓Reason through puzzles with rows, columns, shapes and money.

👨‍🏫 Teaching Tips

→Use the toy picture to model sentences with more than, less than and equal to.
→Conduct the class name-length survey and show results with tally marks or pictures.
→Give puzzles in pairs so children discuss their thinking.
→Provide a mirror for the mirror-number puzzle.
→Use real matchsticks for the zero puzzle.
→Use seeds and a number chart for Ranu's sum-to-17 puzzle; accept all correct answers.
→Encourage children to make their own riddles like Gillu's number 8 questions.

📋 Assessment Questions
