    Subject: Math

    Lesson Length: 30 - 40 mins

    Topic: Ratios and Proportional Relationships; Ratio and Percentage

    Grade Level: 7

    Standards / Framework:

    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.

      • 15% for adequate 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.

    • Provide the option for ELL students to tell the story in their home language.

    • Provide the bill total for students as needed.
