MATERIALS

• US currency play money in a $1, $5, $10 & $20 denominations
• Plant Sale Check Out Sheet
• Clipboards
• Pencils

PROCEDURE

Introduction:

With a week to go until the plant sale, it’s time to practice how to help our customers buy their plants. Students will be in charge of greeting customers, helping them put together an order, tallying their order, taking their cash and making change. Review the denominations of US currency with students and make sure they are familiar with each type of bill. Explain that the students will be in charge of the cash register!

Activity

On the day of the sale, students will have a plant sale check out sheet to keep track of customers’ orders. As a group, model using the sheet to keep track of someone’s order. Make sure students know how to make tally marks. Model adding up an order using the sheet, how to tell the customer their total and how to make change.

Split students into pairs or small groups, depending on teacher preference and student dynamics. Hand out clipboards, copies of the plant sale check out sheet, and some of the play money. Have students role play being a customer and being a plant sale check out clerk, and make sure they switch roles so they both get a chance to practice with the money.

Wrap Up/Assessment: 

Collect the plant sale check out sheets and review students’ math to see if there are any common confusions to clear up before the sale.

FOLLOW UP/EXTENSIONS

• Make posters to advertise for the plant sale
• Practice answering common questions community members may have about the plants
