This is an interesting project that explores which geometrical shapes make the strongest bridge truss structures. It is a good introduction to the engineering design process. You'll design three different trusses, and use online...

[Free Registration/Login Required] In this lesson, students build geometric models of graduation caps using stiff paper. The activity requires the application of skills in finding surface area, understanding similarity, knowing the...

Students will build, extend, describe, predict, graph and generate rules for patterns and functions designed to help students understand the connection between geometric and numerical patterns (younger students) as well as between...

Looks at tessellation artists, including M.C. Escher, Robert Fathauer, and Roger Penrose. This is followed by a discussion of fractals and their similarities and differences to tessellations, and links to lessons and resources on...

In the Islamic culture, circles are considered to be a unit of measurement and the basis for the organization of space. This is illustrated at this site by a series of exercises.

Working as engineering teams, students design and create model beam bridges using plastic drinking straws and tape as their construction materials. Their goal is to build the strongest bridge with a truss pattern of their own design,...

This lesson focuses on a different way to construct geometric figures without tools, Origami. The goal is to make objects out of one or more sheets of paper, without any additional tools like glue or scissors. You can create incredibly...

Text and photographs focus on various figures and geometric shapes: Nazca Candleabra, Nazca Whale, Nazca Rose, and Nazca Hummingbird. Includes a chart of all Nazca designs.
