Lesson Length: 30 - 40 mins
Topic: Ratios & Proportional Relationships; Ratio & Percentage
Brief Description: Students will use percentages in order to determine how much to tip while creating a fun, mathematical comic.
Know Before You Start: Students should be familiar with solving multi-step problems involving ratios and percentages. This could serve as an informal assessment mid-unit.
Hook: Independently or with a partner, have students read the sample comic and work through the steps needed to solve Cirrus’s tipping problem. Regroup as a class to discuss their answers.
Activity:
-
Engage students in a discussion about what a tip is and why we give them.
-
20% for superior service.

Ask students for different real-life scenarios where they or their parents have provided someone with a tip.

The bill total before tip.
