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.

First graders look for geometrical shapes in nature to help them appreciate the diversity of the natural environment.

Middle schoolers 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.

An outstanding lesson plan 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...

Fifth graders classify triangles. In this triangle lesson, 5th graders learn about the characteristics that make up a triangle. They are instructed through video, PowerPoint slides, and teacher-led demonstrations.

Pupils 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 create a scrapbook. In this geometry lesson, students use digital cameras to take pictures of geometrical concepts. Students use the pictures to create a "Geotown" scrapbook.
