Happy Waitress, Mad Waitress

Happy Waitress, Mad Waitress is a Grade 6 percent activity built around calculating a 15% restaurant tip with mental math. Students work from dinner totals, round when useful, find 10% and 5%, and combine those benchmark percentages to estimate an appropriate tip. The restaurant context gives percent computation an immediate practical purpose and encourages flexible strategies instead of calculator dependence.

Use it with partners or small groups when students are practicing percent of a quantity and mental estimation. Compare strategies for amounts that are easy to round and discuss how close an estimate needs to be in a real tipping situation.
