Grade Levels: 3-5, 6-8, 9-12

In this lesson plan, which is adaptable for grades 3-12, students use BrainPOP resources to explore the unifying principles of geometry. Students will identify pertinent questions related to geometry, answer student-generated geometry questions using BrainPOP resources, and share research findings.

Lesson Plan Common Core State Standards Alignments

Students will:

  1. Explore the unifying principles of geometry.
  2. Identify pertinent questions related to geometry.
  3. Answer student-generated geometry questions using BrainPOP resources and share research findings.


  • Internet and projector to show BrainPOP
  • Computers for students to use BrainPOP independently
  • Photocopies of the Activity and Graphic Organizer (can be copied back to back)


geometry; euclidian geometry; point; dimensions; line; plane; compass; protractor; sextant


Use this lesson to introduce or culminate a geometry unit. Prepare copies of the activity and graphic organizer, and determine how students will compile their Q&A (see last step of the procedure.)

Lesson Procedure:

  1. As a warm-up, have students complete the Activity page. Discuss the key terms in the 'Matching' section as a class.
  2. Show students the Geometry movie. Instruct students to listen for different types of geometric figures as they view: no dimensions, one-, two-, and three-dimensional.
  3. Play the movie through again, and this time have students complete the Graphic Organizer. Pause throughout the movie to give them time to take notes on the different types of figures.
  4. Project the Q&A for students to see. Tell students they will be composing their own Q&A questions related to geometry. After showing a few examples, give students time to brainstorm independently or with a partner and determine which questions they'd like to answer.
  5. Give students time to explore the geometry movies available on BrainPOP (listed at the top of this page.) Students who are reading below grade level may complete this activity using the BrainPOP Jr. movies listed above. Each student should watch the movie(s) related to his or her Q&A and compose the answers for the questions chosen.
  6. Compile the class' geometry Q&A. These may be shared on a class blog, Voicethread, podcast, Glogster, or other web 2.0 tool. A low-tech alternative is to create an interactive bulletin board in which the questions are written on slips of paper which can be lifted up to reveal the answers underneath.

Extension Activities:

Take the Geometry POP Quiz together as a class. Then have students compose their own quiz questions. Hold a class competition and see how many questions teams of students can answer correctly!
