Lesson objective: Identify and create different combinations of dollars and coins that make the same amount of money.

This lesson helps to build fluency with identifying and creating equivalent amounts of money. Skip counting on number lines is used here because it helps students to track the values of the coins as they are counting to determine equivalent amounts of money. This work develops students' understanding that different combinations of dollars and coins can make the same amount of money.

Students engage in Mathematical Practice 6 (Attend to precision) as they determine whether groups of dollars and coins show the same amounts of money. Students need to understand the values of these dollars and coins, and be able to accurately skip count in order to find amounts of money and determine whether the groups show equivalent amounts of money.

**Key vocabulary:**

- different groups
- same amount
- skip count
- value

**Special materials needed:**

- dollars and coins
- hundreds grid
- number lines (filled in and blank)
