Introduction to Geometry Lesson Plan

Instructor: Dana Dance-Schissel

Dana teaches social sciences at the college level and English and psychology at the high school level. She has master's degrees in applied, clinical and community psychology.

Kick off your introduction to geometry instruction with a simple class project and a video lesson to guide the way. Suggestions for additional activities and related lessons are included for further instruction.

Learning Objectives:

Upon completion of this lesson, students will be able to:

  • explain the need for geometry
  • identify various geometric shapes
  • list the earliest theorists in geometry
  • apply basic geometric principles to construct a pyramid


1 hour


  • Card stock
  • Rulers
  • Pens/pencils
  • Scissors
  • Tape

Curriculum Standards


Correctly name shapes regardless of their orientations or overall size.


Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.


  • Play the video lesson What is Geometry?, pausing at 00:32.
  • Now have students look around the classroom and list all the different shapes they see. Ask them share what they see with the class, writing the various shapes on the board as students provide them.
  • Play the video lesson again, pausing at 1:13.
  • Have students search online for photographs of the ancient pyramids of Egypt, sharing what they find with the class.
  • Next, play the remainder of the video lesson.
  • When the video lesson is complete, have the students use the internet and work in small groups to research the exterior dimensions of the ancient pyramids of Egypt. Discuss their findings as a class, writing the overall dimensions on the board.
  • Now have students use this information to create a small three-dimensional pyramid of their own using the card stock, rulers, pens/pencils, scissors, and tape.
  • When all students have created a pyramid, have them swap them with a fellow classmate.
  • Next, have the students measure the dimensions of their classmate's pyramid. Record the dimensions on the board. Discuss as a class.

Discussion Questions

  • What similarities do we see in the dimensions of the student pyramids?
  • What were some struggles with creating the 3-D pyramids?
  • How can this project help us understand the importance of geometry in things like architecture and construction?


  • Take a virtual field trip to some of the famous structures of the world. How does geometry factor into their design?
  • Have students look up the course requirements for a Bachelor's degree in architecture. How many geometry classes are required? What other majors focus on geometry? Why?
