Lesson objective: Apply understanding of how different monetary combinations make the same value in order to solve a story problem.

This lesson provides an opportunity for students to apply their knowledge and understanding of making equivalent amounts of money with different combinations to a real-life situation. Students are asked to come up with at least five different ways to make $1.00 for kids to be able to buy a treat at the bake sale.

Key Concept students will use:

- We can make the same amounts of money using different combinations of bills and coins.

Skills students will use:

- skip count by different values to end at the same money amount
- use different coins and understand the values of each to make an amount of money
- understand the equivalence of dollars and coins

Students engage in Mathematical Practice 4 (Model with mathematics) as they show the different combinations of dollars and coins that can be used to make $1.00. Students can use number lines, drawings, and equations to show how the values of the dollars and coins make this amount.
