What This Standard Means
What Students Need to Do
- Students solve coin problems involving quarters, dimes, nickels, and pennies with amounts no greater than one dollar. They add or subtract cent values and write answers using the cent symbol.
What Mastery Looks Like
- A student finds that two quarters, one dime, three nickels, and eight pennies are worth 83¢. If an item costs 68¢, the student finds 15¢ remains and explains the calculation.
Common Misconceptions
- Students may count coins instead of their values, confuse nickels and dimes, or lose track when switching count patterns. They may use dollar notation or decimals before those forms are introduced.
How to Assess It
- Give students 3 quarters, 1 dime, and 4 pennies and price an item at 72¢. Ask whether they have enough and how many cents remain.

Ways to Teach It
Build coin collections with plastic quarters, dimes, nickels, and pennies, then solve a purchase or change problem within 100 cents.
Ask students which coin values they would combine first and how that choice helps track the total.
Play coin-shop challenge by matching collections to prices and calculating change without exceeding one dollar.
Use a classroom menu with cent prices to choose an item, pay with coins, and record the change using ¢.
