3D Surface Area and Volume

Objectives

• Students will analyze and discuss 3D objects and the 2D shapes that make up those objects.
• Students will unfold 3D objects to aid in finding both the Surface Area and Volume of the objects.
• Students will apply this knowledge to finding the Surface Area and Volume of real-world objects.
• Students will try to make a connection with how to understand these topics in IB Mathematics courses and on their final assessments.

Vocabulary

• Circle
• Circumference
• Sector
• Cylinder
• Surface Area
• Volume

About the Lesson

Students will work to solve real-world Surface Area and Volume problems. They will also have a chance to practice the unfolding of 3D objects.
