Dining Out: Understanding Fractions, Decimals, and Percentages When Eating Out
Understand and apply concepts of fractions, decimals, and percentages to count money, make change, figure tax/tips, and participate in other restaurant-related activities
Objective for This Lesson:
Depending upon the needs and abilities of your students, you may select from the following ideas:
1. Students will select items from a menu and count out the total amount needed using the fewest bills and coins possible.
2. Students will determine fractions, decimals, and percentages of the items ordered and/or figure percent/fraction discounts based upon coupons.
3. Students may use the optional “fraction” menu as well, which will encourage them to connect fractions and decimals in the context of money.
How Can You Use This To Differentiate Instruction for Low-Level Students?
1. Have students use the order form that does not include coupon, tax, or gratuity (tip).
2. After students determine their individual totals and count out the bills/coins, have students combine their totals by putting all of their bills/coins together. Next, have students “trade” bills/coins to be sure they have the fewest bills/coins possible while maintaining the correct total.
How Can You Use This for On-Grade Level Students?
1. Ask students to select their items and determine the total as individuals or as a group.
2. Ask students to use the second menu as a unique way for them to determine the relationship between fractions and money.
3. Give the students coupons. Have students determine their subtotal, subtract the coupon discount to get the new subtotal, and then add the gratuity and tax before finalizing their total.
How Can You Use This To Differentiate Instruction for Above-Level Students?
1. Ask students to determine the total order including tax (whatever your state tax is) and 15% gratuity.
2. Ask students to determine the total for a catered party. For this option, the students will use a catering request form to complete the catering order form.
Is there an answer key included?
There is no answer key included because the responses are open-ended and dependent upon so many variables. Did you give them a coupon? If so, which one? Did you require them to use a coupon and add the tax and a gratuity, or did you require them to use a coupon and just add tax? There are too many variables to even begin to make an answer key.
