Grade 2 - Shape and Space

Standard 2.SS.3 - Count and compare sides and corners of two dimensional shapes determining which shape has more or fewer.

Included Skills:

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.
