Overview
This lecture introduces the basics of Australian money, including the types of coins and notes, how to count dollars and cents, and how to combine coins.
Australian Currency Basics
- Each country uses its own type of money, called currency.
- Australia’s currency is the Australian Dollar (AUD).
- Australian money includes both coins and notes.
Coins and Notes
- Australian coins include: 5c, 10c, 20c, 50c, $1, and $2.
- Cent coins are 5c, 10c, 20c, and 50c; these are silver.
- Dollar coins are $1 and $2; these are gold.
- Notes come in $5 (purple), $10 (blue), $20 (red), $50 (yellow), and $100 (green).
Reading and Writing Money
- The dollar sign ($) is used for dollars; the cent sign (¢) for cents.
- A decimal point separates dollars (left) from cents (right).
- 100 cents (100c) equals $1.
Making Dollars with Coins
- Combine cent coins (5c, 10c, 20c, 50c) to total $1 (100c).
- Example: 50c + 50c = $1; 50c + 20c = $0.70 (not enough for $1).
- Example: 50c + 10c + $1 = $1.60 total.
Practice and Examples
- Practice adding different cent coins to create $1.
- Use only silver coins (cents) to make $1 if dollar coins are not available.
