Identify pennies

A penny is identified as the one-cent coin and connected to its denomination: one penny represents 1¢, regardless of its orientation or position among other coins. This understanding supports counting collections of pennies by ones and recognizing that 100 pennies equal one dollar; it does not include making change, using decimal notation, or finding combinations of different coins.

Detailed Explanation: Identify pennies

A penny is the coin worth one cent, written as (1¢)(1\text{¢}).

To identify a penny:

  1. Look for the words “ONE CENT” or the number 1.
  2. A penny may show the front or the back. It is still a penny when it is turned over.
  3. Its place in a group does not matter.
  4. Each penny represents (1¢)(1\text{¢}).

Example: Look at these three coins:

  • Coin A says “ONE CENT.”
  • Coin B says “FIVE CENTS.”
  • Coin C shows the back of a penny with the words “ONE CENT.”

Coin A and Coin C are pennies because each is worth (1¢)(1\text{¢}). Coin B is not a penny because it is worth (5¢)(5\text{¢}).

So, there are 2 pennies, and their total value is

1¢+1¢=2¢.1\text{¢}+1\text{¢}=2\text{¢}.
