TED Talk: House of the Future focuses on the ability of students to render geometric knowledge into physical models and constructions. The project addresses Common Core Standards for Units 1 and 2 Traditional Geometry. It also focuses students on Mathematical Practice 4, Model with Mathematics, and Mathematical Practice 5, Use appropriate tools strategically.
It also focuses students practicing two key 21st Century skills: teamwork and communication.
You can explore the CCSS.
In addition, students will practice using online technologies and other resources to research and examine future global issues, as well as gain exposure to futuristic thinkers as exemplified by TED speakers. If you want to review the project outcomes again, go back to the.
Timeline & Duration
- 4 weeks, based on approximately 5 hours of class time per week
- Project Rating: Advanced
In previous grades, students were asked to draw triangles based on given measurements. They also have prior experience with rigid motions: translations, reflections, and rotations and have used these to develop notions about what it means for two objects to be congruent. In this unit, students establish triangle congruence criteria, based on analyses of rigid motions and formal constructions. They use triangle congruence as a familiar foundation for the development of formal proof. Students prove theorems—using a variety of formats—and solve problems about triangles, quadrilaterals, and other polygons. They apply reasoning to complete geometric constructions and explain why they work.
