Grade 2 - Shape and Space
Standard 2.SS.5 - Practice identifying two dimensional shapes contained within three dimensional shapes.
Included Skills: Geometry
Demonstrate understanding of the relationship between 2-D shapes and 3-D objects. • Analyze the differences between two pre-sorted sets of objects and/or pictures of shapes and explain how the objects and shapes were sorted. • Analyze a set of objects and/or pictures of shapes to identify two common attributes of each member of the set. • Describe the faces of a personally relevant 3-D object by comparing the faces to 2-D shapes (such as triangles, squares, rectangles, or circles). • Analyze (using concrete models of 3-D objects) a set of descriptions of the 2-D faces of a 3-D object to identify the 3-D object (e.g., "A 3-D object has one rectangular face and four triangular faces - what type of object is it?" "A pyramid."). • Analyze and correct the statement "The tissue box is a rectangle"
