Describing 3D shapes in Pre-K and Kindergarten is now an expectation as it is a key geometry standard. This resource contains 3D shapes activities and resources for practicing this standard. Included are chants, videos, games, poetry,...

In this project, you will make 2-dimensional templates, called nets, that fold up into 3-dimensional (3-D) shapes. By making shapes of different sizes, you will be able to see how 3-D shapes change with size. In your findings you will...

This interactive exercise focuses on volume equations, measurement, and problem solving skills to compare the volume of 3D figures constructed from similar amounts of construction materials.

Using an engaging approach, this lesson plan requires students to record the volume of cylinders as a function of the radius. Students will construct and measure the volume of several cylinders and then begin comparing these shapes.

This interactive exercise focuses on discovering the relationships between two and three-dimensional shapes.

[Free Registration/Login Required] This is a formative assessment task where students are asked to use geometric solids to model each of four tent shapes on a worksheet and use mathematical language to describe them. Samples of student...

In this video segment [3:25] from Cyberchase, a plant expert shows Bianca the patterns and symmetry found in nature.
