The student must be able to identify three-dimensional figures, including spheres, cones, cylinders, rectangular prisms, and triangular prisms. The students must be able to see that a cube is a special rectangular prism. Students must also be able to explain and justify their mathematical ideas and arguments about these figures using formal geometric language.

1.6 Geometry and measurement. The student applies mathematical process standards to analyze attributes of two-dimensional shapes and three-dimensional solids to develop generalizations about their properties. The student is expected to:
(E) identify three-dimensional solids, including spheres, cones, cylinders, rectangular prisms (including cubes), and triangular prisms, and describe their attributes using formal geometric language
