Perfectly Proportionate… or Are They?

Subject: Math

Lesson Length: 25 - 35 mins

Topic: Ratios & Proportional Relationships; Proportional Relationships

Grade Level: 7

Standards / Framework:

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: Ask students to turn to a partner and explain how they know if two quantities are proportional. Share several responses to check for understanding.


  • Students will choose one of the sample comic panels to respond to.

    • 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.

    • 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 two to four panel comic explaining whether or not the two quantities in the sample they chose are proportional. 

Closure: As a class, students will decide which sample comic panel is proportional and which is not.


  • Allow students to use speech-to-text. 
  • Provide sentence frames and/or key words for the student comic.
  • Allow students to work with a partner.


  • Comic to print or display: Comic.
  • Students may need scrap paper to determine if the quantities are proportional before creating their comic.
