Indian Coins

Indian Notes (Banknotes)

How to Count Money:

1. Sort by value - Group coins and notes of same value together
2. Start with largest - Count biggest notes first (₹500, ₹200, ₹100...)
3. Count each group - Add up all notes/coins of same value
4. Add all together - Find the total amount

Example: Count the Money

How to Compare Money Amounts:

1. Count each picture - Find the total amount in Picture A and Picture B
2. Write both amounts - Write them clearly

Steps to Check:

1. Find the price - How much does the item cost?
2. Count your money - How much money do you have?

4. Answer:
   • If your money ≥ price → YES, you have enough! ✓

Formula:

If \(\text{Money you have} \geq \text{Price}\), then YES!
If \(\text{Money you have} < \text{Price}\), then NO!

What is a Price List?

A price list is a table or list that shows the prices of different items. We use it to find costs and calculate totals!

Example Price List: School Store

Using Price Lists:

Counting Money:

\(\text{Total} = (\text{Number of notes/coins}) \times (\text{Value})\)

Making Change:

\(\text{Change} = \text{Money Given} - \text{Price}\)

Adding Money:

\(\text{Total} = \text{Amount 1} + \text{Amount 2} + ...\)

Subtracting Money:

\(\text{Remaining} = \text{Starting Amount} - \text{Spent}\)
