Brief Description: Students will use percentages in order to determine how much to tip.

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:

• Have students read the sample comic and work through the steps needed to solve Cirrus’s tipping problem. Regroup as a class to discuss answers.

Activity:

• Engage students in a discussion about what a tip is and why we give them.

• 20% for superior service.

• 10% for unsatisfactory service.

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

• Students will create a five-panel comic telling a story about a situation where they need to provide a tip. Students should include:

• The scenario that requires a tip, e.g., restaurant, hair cut, car wash, nail salon, Uber ride, etc.

• The bill total before tip.

• The tip percentage.

• The tip amount.

• The total bill amount including tip.

Closure:

• Share and discuss the completed comics.

Differentiation:

• Allow students to use the speech-to-text feature.
• Allow students to use the voiceover feature to read their comics aloud.
• Provide sentence frames for the story.

• Allow students to work in pairs or groups as needed.
