Lesson Length: 25 - 35 mins
Topic: Ratios and Proportional Relationships; Proportional Relationships
Brief Description: Analyze proportional relationships and use them to solve real-world and mathematical problems.
Know Before You Start: Students should be familiar with proportional quantities prior to this lesson. This lesson could be used as a formative assessment to gauge student understanding of proportional quantities.
- Have students turn to a partner and explain how they know if two quantities are proportional. Share several responses to check for understanding.
Have students choose one of the sample comic panels and respond to the following:
If they are proportional, explain and justify how you know.
If they are not proportional, explain and justify how you know and provide a number that would make the relationship proportional.
Use a caption at the top of you comic to denote which sample comic you are referring to (1 or 2).
- Have students create a comic explaining whether or not the two quantities in the sample they chose are proportional.
- As a class, have students decide which sample comic panel is proportional and which is not.
- Allow students to use the speech-to-text feature.
- Provide sentence frames or key words as needed.
- Allow students to work with a partner.
