4.8c 2D and 3D figures

4.8  The student identifies and describes attributes of geometric figures using formal geometric language
PK	K	1	2	3	4	5
-Sort and describe similarities and differences between objects. -Sort objects into groups by an attribute and begin to explain how the grouping was done. -Recognize, describe, and name four common shapes (circles, triangles, rectangles, squares).	K.8b  Compare two objects based on their attributes. K.8c  Sort a variety of objects, including two- and three-dimensional geometric figures, according to their attributes and describe how the objects are sorted. K.9a Describe and compare the attributes of real-life objects such as balls, boxes, cans, and cones or models of three-dimensional geometric figures.	1.6c  Describe and identify 2D and 3D geometric figures in order to sort them according to a given attribute using formal and informal language 1.6b  Describe and identify 3D figures, including spheres, rectangular prisms (including cubes), cylinders and cones. 1.6a  describe and identify 2D geometric figures, including circles, triangles, rectangles, and squares (a special type of rectangle)	2.7a  describe the attributes (the number of vertices, faces, edges, and sides) of 2D and 3D geometric figures such as circles, polygons, spheres, cones, cylinders,prisms, and pyramids. 2.7b  Use attributes to describe how two 2D figures or two 3D figures are alike or different	3.8  The student is expected to identify, classify, and describe 2D and 3D geometric figures by their attributes.  The student compares 2D figures, 3D figures, or both by their attributes using formal geometric vocabulary	4.8c   Use essential attributes to define 2D and 3D geometric figures	5.7 The student is expected to identify essential attributes including parallel, perpendicular, and congruent parts of 2D and 3D geometric figures
Use essential attributes to define 2D geometric figures Use essential attributes to define 3D geometric figures Use:  to employ for some purpose; put into service; make use of Define:  to state the precise meaning of (a work or sense of a word, for example) to describe the nature or basic qualities of; explain
