In this video students learn the basics of antiprisms, in the context of New York’s Freedom Tower, which has an antiprism design.

In this video students learn the basics of rectangular prisms, in the context of a New York residential tower: 432 Park Avenue.

In this video students study a real-world application of triangular prisms: The Flat Iron Building in New York City.

In this video students learn the basics of prisms and anti prisms.

In this program we explore the properties of three-dimensional figures. We do this in the context of two real-world applications.
