Money problem: A situation where you need to count money to buy something
- Count the money you have
- Check the price of the item
- Compare your money to the price
- Decide if you have enough
2 dimes = 2 × 10¢ = 20¢
1 nickel = 1 × 5¢ = 5¢
Total = 20¢ + 5¢ = 25¢
Candy bar costs 25¢
Sarah has 25¢
25¢ = 25¢, so Sarah has exactly enough money!
Yes, Sarah has exactly 25¢, which is enough to buy the candy bar that costs 25¢
• Count your money first: Before buying anything
• Compare amounts: Your money vs. the price
• Make decisions: Enough money or not enough
Saving: Putting money aside over time to buy something
1 quarter = 1 × 25¢ = 25¢
2 dimes = 2 × 10¢ = 20¢
3 pennies = 3 × 1¢ = 3¢
Total = 25¢ + 20¢ + 3¢ = 48¢
Toy costs 50¢
Tom has 48¢
48¢ < 50¢, so Tom needs more money!
No, Tom has 48¢ but needs 50¢, so he is 2¢ short of buying the toy
• Plan ahead: Know how much you need before saving
• Track progress: Count how much you've saved
• Calculate difference: How much more you need
Change: The money you get back when you pay more than the price
Lisa gave 50¢
Juice box costs 30¢
Change = Paid - Price = 50¢ - 30¢ = 20¢
Price + Change = 30¢ + 20¢ = 50¢ (what Lisa paid)
Lisa should get 20¢ in change from the cashier
• Subtract to find change: Amount given - Price = Change
• Check your change: Make sure it's correct
• Keep receipts: Track your spending
