### Preparations

- Make copies of the “Flower Show Price List” (1 per student).

- Prepare the index cards numerically showing various amounts of money (from $2.00 to $4.50 choosing increments appropriate for your class).
- Make an overhead transparency (or photocopy) of the Mississippi quarter reverse.

### Worksheets and Files

Lesson plan, worksheet(s), and rubric (if any) at www.usmint.gov/kids/teachers/lessonPlans/pdf/292.pdf.

### Session 1

- Describe the 50 State Quarters® Program for background information if necessary, using the example of your state if available. Then display the overhead transparency or photocopy of the Mississippi quarter reverse.
- Explain to students that the design was specially chosen to represent the state of Mississippi. Tell students that all states have state flowers and ask if students know what flower was chosen to represent their home state. (If the home state is Missis- sippi, give general examples of other states’ flowers.)
- Distribute the “Flower Show Price List” and the accompanying worksheet. Review the information that is given about each state on the price list.
- As a class, complete Part 1 of the “Flower Show Worksheet.” Solve each problem on the board, explaining and giving more examples of mathematical concepts when necessary.

### Session 2

- Ask students to pretend that they will be constructing their own flower garden using the information they have about the state flowers. Have them choose two flowers from the list that they would like to buy. These may be the same type of flower. Direct them to record their choice in Part 2 of the “Flower Show Worksheet.”
- Put them into groups of two to four. Randomly pass out the index cards. Explain that this is the amount that they may “spend” on flowers and will be combined to create their group garden.
- Have students add up the group money and record this number in Part 2.
- As a group, have the students complete Part 3 on the “Flower Show Worksheet.”
- Check the worksheets for accuracy.

### Differentiated Learning Options

- Ask students to graph the prices and values of each state’s flower.
- Adjust the prices on the price list for your students’ level and put them on index cards.

### Enrichments/Extensions

- Have students research the state flowers of their home state or another state that is meaningful to them. Have them create their own State Flower Show information and display their illustrations on a bulletin board.
- Have students plant a class flower garden using their state flower, and chart the growth of each flower.

Use the worksheets and class participation to assess whether the students have met the lesson objectives.
