Students will determine whether data shown in a table or graph represents a proportional relationship with this interactive True or False Red Card/Green Card PowerPoint Activity.
Distribute one red card and one green card to each student. Cards can be made from construction paper (approximately 4 × 6 inches) and laminated for repeated use throughout the year.
Run the PowerPoint presentation. For each problem, students decide whether the given data represents a proportional relationship. If the relationship is proportional (true), they hold up their green card. If the relationship is not proportional (false), they hold up their red card. For proportional relationships, you may also ask students to identify the constant of proportionality. Fractional constants are included, and students must also be able to work with decimals.
Students can check their answers by clicking the green check or red X. Correct answers trigger an applause sound, while incorrect answers trigger a buzzer. There are 25 questions total. Use the activity all at once or break it up for multiple uses as review, a warm-up, or an exit ticket.
