Money: Currency used to purchase goods and services. In the US, money comes in dollars ($1, $5, $10, $20) and coins (penny, nickel, dime, quarter).
Word Problem: A math problem presented in the form of a story or real-life situation that requires mathematical operations to solve.
Cost: The amount of money needed to buy something.
Change: The money returned when you pay more than the cost of an item.
Total: The sum of all amounts being added together.
Rule 1 - Addition: Use addition when finding the total cost of multiple items or combining amounts of money.
Rule 2 - Subtraction: Use subtraction when finding change or comparing amounts of money.
Rule 3 - Multiplication: Use multiplication when finding the total cost of multiple identical items.
Rule 4 - Division: Use division when sharing money equally or finding unit costs.
Rule 5 - Money Operations: Always align decimal points when adding or subtracting money amounts.
Step 1: Read the Problem Carefully - Identify what information is given and what you need to find.
Step 2: Identify the Operation - Determine whether you need to add, subtract, multiply, or divide.
Step 3: Set Up the Equation - Write down the numbers and operation needed to solve the problem.
Step 4: Solve the Problem - Perform the calculation carefully, paying attention to decimal placement.
Step 5: Check Your Answer - Make sure your answer makes sense in the context of the problem.
Simple Example: Sarah has $5 and wants to buy a candy bar that costs $2. How much money will she have left? $5 - $2 = $3. Sarah will have $3 left.
Intermediate Example: Tom buys 3 books that cost $4 each. How much does he spend in total? 3 × $4 = $12. Tom spends $12 in total.
Advanced Example: Emma has $20. She buys a shirt for $12 and a pair of socks for $3. How much change does she receive? $12 + $3 = $15 spent. $20 - $15 = $5 change.
Complex Example: Four friends want to share $24 equally. How much money does each friend get? $24 ÷ 4 = $6. Each friend gets $6.
Tip 1 - Read Carefully: Underline important information in the problem to help focus on what's needed.
Tip 2 - Draw Pictures: Draw coins or bills to visualize the money amounts when needed.
Tip 3 - Estimate First: Round numbers to estimate the answer before calculating to check reasonableness.
Common Pitfall 1: Forgetting to include the dollar sign ($) in your final answer.
Common Pitfall 2: Misaligning decimal points when adding or subtracting money amounts.
Note 1: Always write money amounts with a dollar sign ($) and two decimal places (e.g., $5.00).
Note 2: When finding change, subtract the cost from the amount paid.
Note 3: When buying multiple identical items, multiply the cost by the quantity.
Note 4: When sharing money equally, divide the total by the number of people.
Note 5: Check your answer by doing the opposite operation (addition to check subtraction, etc.).
Sarah has $10. She buys a book for $7. How much money does she have left?
Tom buys 4 pencils that cost $0.50 each. How much does he spend in total?
Emma has $15. She spends $8 on lunch. How much money does she have left?
Jake buys a toy for $12 and a game for $18. How much does he spend in total?
