Introduction Introduction

Hold up each coin and review its name and value. You may want to print out and display the Coin Values reproducible for students to use as a reference. Be sure to show students both sides of each coin, and remind them that larger coins do not necessarily have greater values.

Procedure Procedure

  1. Provide each student with a set of plastic coins or paper coins that have been cut out from the reproducible.
  2. On chart paper, write a value such as “20.” Ask students, “What coins can you add together to make 20 cents?” Give one or two students an opportunity to respond.
  3. Next, ask, “What if I asked you to use exactly two coins to make 20 cents? Which coins would you use?” Call on student volunteers until a student gives the right answer (two dimes).
  4. Then ask, “What if I asked you to use exactly four coins to make 20 cents? Which coins would you use?” Call on student volunteers until a student gives the right answer (four nickels).
  5. Repeat the activity a few more times using different amounts, such as 10 cents, 13 cents, 22 cents, 40 cents, etc. Ask students to make each amount two or three different ways.

Independent Practice Individual Practice

  1. Give each student a copy of the Mystery Coins reproducible.
  2. Ask students to look at the first line on the reproducible. Tell them to place different coins on the circles until they have two that make 15 cents.
  3. Instruct students to write down how many of each coin they used.
  4. Prompt students to continue until they have completed the reproducible.
