## Lesson: Comparing Money Amounts

Developing the Concept

In this lesson, students extend their understanding of money to making change.

**Materials:** play money for each group of students: $20, $10, $5, and $1 bills; half-dollars, quarters, dimes, nickels, pennies

**Preparation:** Distribute play money to each group.

**Prerequisite Skills and Background:** Students should know the value of coins and bills and how to write amounts of money. Students should also be able to count by 5s, 10s, 20s, and 25s.

**Wrap-Up and Assessment Hints**

Point out to students that when they find change, they count on from the cost of the item to the amount paid by using bills and coins of increasing, not decreasing, value. Remind them to start with smaller values, then progress to greater values. When you assess students, have them explain the strategies they used to find change.
