Percent Word Problems – Tipping & Gratuities Math

About this resource

What's inside this resource

Tipping is becoming more and more common and the amount you are expected to tip is increasing too. Make sure your students understand what tipping is and how to calculate a tip- useful life skills!

Here’s a ready-to-print real-life percent math lesson for middle school students (in grades 6-9) or special education or life skills classes in a high school setting.

Teach your class all about tipping culture and tips in both Canada and the United States.

Why do people tip or give certain people a gratuity?
What places do we tip? What places do we not?
Has tipping been increasing recently ("tip-flation")?

Show students how the math skills and concepts that they have been learning in class (percentages, decimals, division, fractions) can be useful in their everyday lives!

How to Use:

1. The first page is a handout that you complete with your students (with fill-in-the-blanks) to teach them the ins and outs of tipping: where and when you do it, etc.

2. The second page teaches students two simple methods of calculating tips (using well-known percentage benchmarks OR multiplying the price by a percentage written in decimal form). Encourage your students to determine a third method they could use.

3. After that, there are 7 practice word problems of realistic tipping situations that your students can complete. From tipping for a meal to paying at a salon, or even calculating tax AND tip together, your students will get a lot of real-life practice completing these problems in small groups or own their own.

4. To finish, you can have a class discussion about tipping in general and what your students think about our system.

Teaching tips & learning objectives

Learning objectives

Calculate a percentage tip using either percentage benchmarks (e.g., 10% doubled to 20%) or decimal multiplication
Apply percent calculations to seven real-world service scenarios, including one combining tax and tip in a single total
Compare tip amounts across different bill totals and explain whether the difference seems fair
Form and support an opinion about tipping culture using evidence from the lesson

Teaching tips

Use the page 1 fill-in-the-blank handout as a whole-class discussion to build background before introducing the calculation methods on page 2
Have students attempt to find a third way to calculate Jacob's $24 tip before revealing the alternate method in the answer key (dividing by 5 for 20%)
Problem 7 combines tax and tip in one multi-step calculation; consider modeling it together first since it is a step up from the earlier single-step problems
Save the closing reflection question for a class discussion, either before or after students write their own response, as the file itself suggests

Skills covered

Percent-of-a-quantity calculation — students find a percentage tip using benchmark reasoning or decimal multiplication across seven real-world problems.
Multi-step problem solving — students combine a sales-tax calculation with a tip calculation to find a grand total in Problem 7.
Comparative reasoning — students compare tip amounts on two different bills and explain whether the size of the difference makes sense.
Persuasive/opinion writing — students form and support an opinion about tipping culture using lesson evidence.

Good to know

Questions teachers ask about this resource

Does the lesson only cover one method for calculating a tip, or several?

Two are demonstrated directly — using percentage benchmarks (finding 10% and adjusting) and multiplying by a decimal — and students are also prompted to think of a third method on their own.

Which practice problem combines tax and tip in one calculation?

Problem 7 has students calculate a meal total, add sales tax, then add a tip on top to reach a single grand total.

Curriculum

Standards, concepts & topics

Standards

6.RP.A.3 — Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations. a. Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios. b. Solve unit rate problems including those involving unit pricing and constant speed. For example, if it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours? At what rate were lawns being mowed? c. Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole, given a part and the percent. d. Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.
7.RP.A.3 — Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.
