An outstanding activity on triangles awaits your math scholars. Learners focus on the triangle, which is the strongest of all polygons. They see the role that triangles play in the design of buildings, and learn about triangle...

Middle and high schoolers explore the concepts of architectural rigidity. They analyze a variety of polygons, and explain why some shapes add more strength to structures than others. The PBS video, "Building Big," is utilized in this plan.

Students are introduced to the notion of surface area and volume. Students review surface area and volume by finding the area of a two-dimensional shape. They practice using the computer to create different surface area shapes.

Young scholars build a Lego design and then work with a partner to reproduce that design. They guide the building of the reproduction by description only and then check their work.

Students work collaboratively to design and construct a roof out of Legos for a house that was built in a previous lesson. The roof must be structurally sound and pass certain criteria determined by the teacher.

Students identify and examine various Lego building materials. They discover how to measure Lego blocks and cut out and paste pictures of the Legos on the Engineer's Parts List sheet.
