Tax, Tip, and Markup Practice for 7th Grade
By Martin J.
A practice packet for 7th graders that teaches sales tax, tips, and markup as one repeated skill: finding a percent of an amount and adding it on. It opens with key terms and a worked example on a hardware store lamp, then moves students through guided practice, building proportional reasoning and fluency with percents and decimals.
Customize for your classroom
Teacher Guide & Tips
- Use as a 45-minute review block after a unit on percents, either as a whole-class worked-example walkthrough followed by independent practice.
- Discussion question: Why does finding a tip and adding sales tax use the same steps, and how could you check whether a total is reasonable?
- Scaffold for struggling readers: have them underline the three key terms and rewrite the 'To find a percent of an amount' rule in their own words before attempting problems.
- Extension for advanced students: ask them to compare a 15% tip on a $40 bill with a 6% sales tax on the same amount, and explain which addition is larger and why.
- Estimated time: about 45 minutes for the worked example and practice problems, plus 5 minutes for a quick self-check at the end.
