Subject: Math

Lesson Length: 30 - 45 mins

Topic: The Number System; Positive & Negative Numbers

Standards / Framework:

Brief Description: In this lesson, students will describe the elevations and temperatures of locations using positive and negative numbers.

Know Before You Start:

• Students should understand the relationship of positive and negative numbers with their relationship to zero.

• This lesson would integrate well with a geography unit.

Hook: Read and discuss the sample comic.

• Do you think there’s a relationship between temperature and elevation?
• What are some other ways negative and positive numbers can be used?

Activity:

• Have students choose a location around the world that meets one or both of the following criteria:

• Elevations above and below sea level.

• Experiences high and low temperatures that include negatives.

• Have them research their chosen location in order to find specific positive and negative temperatures and/or elevations.

• Using the sample comic as a guide, have students create a two-to-three-panel comic explaining the high and low temperatures and elevation above and/or below sea level.

Closure: Have students rotate around the room in a gallery walk to read each other’s comics. This will allow them to experience more negative numbers in context and learn about different places around the world.

Differentiation:

• Provide specific locations for students as needed.

• Display student comic expectations.

Resources:

• Comic to print or display: Comic.
