How Much Can We Spend? (Money) — NCERT Solutions

Concept: The same amount of money can be made in more than one way using different notes and coins. This is called making combinations.

Example — How to make ₹20 in different combinations:

Verification for Combination 4:
$$10 + 5 + 5 = 20 ✓$$

Steps to solve any such question:

1. Note the amount to be shown.
2. Think of notes and coins available (₹1, ₹2, ₹5, ₹10, ₹20).
3. Choose different groups of notes/coins that add up to the given amount.
4. Draw or fill in the boxes with those notes/coins.

(Students should apply these steps to each amount shown in their textbook images and draw/fill the appropriate currency in the boxes provided.)

Concept: Two different groups of coins/notes that add up to the same total amount should be matched together.

Steps:

1. Add up the value of all coins/notes in the left group.
2. Add up the value of all coins/notes in each right group.
3. Draw a line from the left group to the right group that has the same total.

Example:

• Left side: Two ₹5 coins → $5 + 5 = ₹10$
• Right side: One ₹10 note → $₹10$
• These are equal, so draw a line between them.

(Since the images are not visible, students should apply the above method to the actual coins/notes shown in their textbook for part A and draw the matching line.)

Concept: Find the total of each group and match equal totals.

Steps:

1. Count and add the value of coins/notes on the left side.
2. Count and add the value of coins/notes on each option on the right side.
3. Draw a line connecting the left group to the right group with the same total.

Example:

• Left side: One ₹10 note + one ₹5 coin → $10 + 5 = ₹15$
• Right side: Three ₹5 coins → $5 + 5 + 5 = ₹15$
• These match → draw a line.

(Apply this method to the actual images in your textbook for part B.)

Concept: Find the total of each group and match equal totals.

Steps:

1. Add the value of all coins/notes shown on the left.
2. Add the value of all coins/notes shown on each right-side option.
3. Draw a line from the left group to the right group whose total is equal.

Example:

• Left side: Two ₹10 notes → $10 + 10 = ₹20$
• Right side: Four ₹5 coins → $5 + 5 + 5 + 5 = ₹20$
• These match → draw a line.

(Apply this method to the actual images in your textbook for part C.)

Points to discuss:

1. When we save money, we can use it later when we really need something important.
2. Saving helps us buy things that cost more money, like books, toys, or gifts.
3. We can keep saved money in a gullak (piggy bank) at home.
4. Saving money is a good habit because it teaches us to be careful and responsible with money.
5. Even saving a small amount every day adds up to a big amount over time.

Example: If you save ₹2 every day, in 10 days you will have:
$$2 \times 10 = ₹20$$

Conclusion: Saving money is a very good habit. It helps us in times of need and teaches us the value of money.

Steps to make a Gullak (Piggy Bank):

1. Take a spare box (like an empty matchbox, shoebox, or any small cardboard box).
2. Ask an elder or sibling to help you cut a small slot (opening) on the top of the box — just big enough for a coin to pass through.
3. Decorate the box with colours, stickers, or drawings to make it look nice.
4. Your gullak is ready!

How to use it:

• Drop coins or small notes into the slot every day.
• Do not open it until you have saved enough for something you want.

What we learn: This activity teaches us the value of saving money and being responsible. It also shows us how small savings grow into a bigger amount over time.

Example: If you put ₹1 in your gullak every day for 30 days:
$$1 \times 30 = ₹30$$
You will have ₹30 saved at the end of the month!
