One real-world task is the ability to explain what you know to others. The challenge in this project is for older students to find common examples of right-angle geometry and use their geometric knowledge to create a lesson that explains Pythagorean principles to younger students in a way that is engaging, understandable, meaningful, and relevant. |

## The Scenario and Challenge

Students will create a five minute lesson on the Pythagorean theorem suitable for an elementary audience. The lesson may be digital, such a web page or a video, or it may be a song, skit, or game if technology is not available. The lesson must include key facts about right triangles, the Pythagorean theorem and its proof, and at least one real-world application. Students can choose their own examples or choose from a list:

- Building a wheelchair ramp for a family member
- Fitting a flat screen TV into an existing entertainment center
- Adding an additional room and roof onto a building
- Manufacturing a tent
- Showing Pythagorean examples from existing school buildings.

Students must also be able to answer the Driving Question by demonstrating that their presentation or performance led to engagement and understanding by the audience.

Students can choose their audience, ranging from lower elementary to middle school students.

The challenge in this project is for older students to use common examples of right-angle geometry and Pythagorean theorems to demonstrate Pythagorean principles to younger students in a way that is engaging, understandable, meaningful, and relevant.

For digital presentations, students work in pairs or small teams. For performances, teams may be slightly larger.

## The Driving Question

Present this Driving Question to your students:

*How can we present the Pythagorean theorem to an audience of younger students in a way we know is understandable, relevant, and meaningful? *
