Coin riddles: a 20-minute 1st grade money game
What it is: a 1st grade math game where students solve riddles about U.S. coins using real clues: color, size, edge and value. The surprise that the dime is smaller than the nickel but worth more helps students learn that the size of a coin does not tell its value.
Time: about 20 minutes. Grade: 1st grade.
Materials: one penny, nickel, dime and quarter for each pair (or coin pictures), a magnifying glass if you have one, and riddle cards written on index cards.
- Read a model riddle: "I am silver. My edge is bumpy. I am the smallest coin, but I am worth 10 cents. What am I?" (a dime)
- Pairs look closely at their coins and feel the edges to check the answer.
- Read 5 more riddles, for example: "I am brown and worth 1 cent." "I am bigger than a dime and smooth. I am worth 5 cents." "I am the biggest of the four and worth 25 cents."
- Pairs hold up the coin that answers each riddle.
- Each pair writes a new riddle with two clues about how the coin looks and one clue about its value.
- Pairs trade riddles and solve each other's.
Safety: count the coins in and out, and remind students to keep coins out of their mouths. Wash hands after handling money.
Differentiation: students who need support use a coin chart with names and values. Students who are ready write a riddle about two coins together: "We are two coins that make 30 cents." English learners can use the words bigger, smaller, smooth and bumpy.
Quick check: ask a student which coin is worth more, a nickel or a dime, and which one is bigger.
