What This Standard Means
What Students Need to Do
- Students count the value of mixed coins and make the same amount using different coin combinations. They solve buying and payment problems with coins and dollar bills, then use $ and ¢ correctly.
What Mastery Looks Like
- Students count mixed coins accurately by starting with the greatest value and counting on. They show more than one way to make an amount and label answers correctly with $ or ¢.
Common Misconceptions
- Students may count the number of coins instead of their values. They may confuse nickels and quarters, count mixed coins in random order, or use $ and ¢ together incorrectly.
How to Assess It
- Give students this exit ticket: “Show two coin combinations for 63¢, then write the total value of one dollar, two dimes, and four pennies.”
Lesson moves
Ways to Teach It
Give pairs coin cups and amount cards; students build each amount two ways, count aloud, and record both equations.
Ask, “Mia made 47¢ with five coins; what coins could she have used?” Students write and compare possible answers.
Play Coin Target: draw a card under 100¢, then race to make the amount with the fewest coins.
Set up a class store with prices and dollar bills; shoppers choose coins for exact payment and write each purchase total.
