Grade 2 - Shape and Space
Standard 2.SS.3 - Count the faces of three dimensional shapes.
Included Skills: Geometry
Describe, compare, and construct 3-D objects, including: • cubes • spheres • cones • cylinders • pyramids. • Identify examples of cubes, spheres, cones, cylinders, and pyramids as found in the classroom, home, and community. • Sort a set of personally relevant 3-D objects and explain the sorting rule used. • Compare the attributes of cubes, spheres, cones, cylinders, and pyramids and generalize descriptions of each category of 3-D objects. • Compare two 3-D objects of the same type (e.g., both are cylinders) and explain how the dimensions of the objects can be used to compare the objects (one-to-one correspondence or non-standard units). • Compare two 3-D objects in different orientations (e.g., "If I was to flip this object over, the two objects would have the same height."). • Create and describe a concrete representation of a personally relevant 3-D object. • Sort 3-D objects according to two attributes and explain the sorting rule used.
