Subject: Math
Lesson Length: 25 - 35 min
Topic: Ratios & Proportional Relationships- Proportional Relationships
Grade Level: 7
Objective: Explanation
Standards: CCSS.MATH.CONTENT.7.RP.A.2. A,B,C
Brief Description: Analyze proportional relationships and use them to solve real-world and mathematical problems. Students will justify and explain if two given quantities are proportional.
Know Before You Start: Students should be familiar with proportional quantities prior to this lesson. This lesson could be used as a checkpoint or formative assessment to gauge student understanding of proportional quantities.
Hook: Students should turn to a partner and explain how they know if two quantities are proportional. Share several responses to check for understanding.
Activity:
- Students will choose one of the sample comic panels to respond to.
- Students will use a caption at the top of their comic to denote which sample comic they are referring to (1 or 2).
- Students will create a 2-4 frame comic explaining whether the two quantities in the sample they chose are proportional or not.
- If they are proportional, students will explain and justify how they know.
- If they are not proportional, students will explain and justify how they know and provide a number that would make the relationship proportional.
Closure: As a class, students will decide which sample comic panel is proportional and which is not.
Resources:
- Students may need scrap paper to determine if the quantities are proportional before creating their comic.
- Example comic to print or display: Comic
