Discovering How to Find Surface Area of Right/Rectangular Prisms


Lesson Objectives:

  • Answer this essential question: How can we solve for the surface area of a rectangular prism?
  • Understand the mathematical reason behind the procedure to solve for surface area.
  • Build their own formula to solve for surface area of a right prism (also known as a rectangular prism) and perservere to simply it to make it more effecient. Simplifying the formula to make it more efficient is a possible extension. We are primarilu concerned with conceptual understanding of how to construct surface area for a right prism.
  • Apply the mathematical reasoning to real-world problems and math problems.

Keywords: area, surface area, right prism or rectangular prism, multiply, sum, length, width
