6th Grade Finding Percentages of Amounts Quizzes

Sixth grade is where percentage calculations become fully formalized, so it's worth spending time on all three forms of the core relationship: finding a percentage of an amount, finding what percent one number is of another, and finding the whole when a percentage is known. For finding a percentage of an amount specifically, the decimal-multiplication method (multiply by the decimal equivalent) is the most transferable approach — it scales cleanly to tax, discount, and tip problems students will see throughout middle school.

Mix problem types deliberately: bare calculations (find 18% of 350), single-context word problems (a $45 item is on sale for 20% off — what is the discount?), and multi-step problems (find the sale price after the discount). The jump from bare calculations to multi-step word problems is where sixth graders most often stall, so that middle tier of single-context problems does real work.

Two errors dominate at this level. First, students confuse "find 20% of 80" with "find 80% of 20" — they get the same answer here, which masks the confusion until numbers are less symmetric. Second, in multi-step problems like finding a sale price, students find the discount correctly but forget to subtract it from the original. Building the habit of labeling what each calculated value represents helps catch that second error.

Download the PDF and print for traditional classroom use — every quiz includes a complete answer key so you're ready to go immediately. You can also host the quiz as a digital quiz on Wayground, which is useful for homework or independent practice where you want automatic scoring. Both formats cover the same problems, so switching between them based on the day's setup is straightforward.

Yes — this is one of the central topics in Common Core's sixth-grade ratio and proportional reasoning domain. Students are expected to understand percent as a rate per hundred and use that understanding to find a percentage of a quantity, which is exactly what these quizzes practice. It builds directly from fifth-grade decimal multiplication and sets up the percent-change and proportional-relationship work that runs through seventh grade.

For students who are still shaky on decimal conversion, start them on problems where the percent is a benchmark (10%, 25%, 50%) before introducing arbitrary percentages. For students with reading challenges, Wayground's Read Aloud feature reads word problems aloud so language difficulty doesn't interfere with math performance. You can also adjust font size and spacing at the quiz level for students who need it, without creating a separate version of the assignment.
