(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:
- (A) classify and sort regular and irregular two-dimensional shapes based on attributes using informal geometric language;
- (B) distinguish between attributes that define a two-dimensional or three-dimensional figure and attributes that do not define the shape;
- (C) create two-dimensional figures, including circles, triangles, rectangles, and squares, as special rectangles, rhombuses, and hexagons;
- (D) identify two-dimensional shapes, including circles, triangles, rectangles, and squares, as special rectangles, rhombuses, and hexagons and describe their attributes using formal geometric language;
- (E) identify three-dimensional solids, including spheres, cones, cylinders, rectangular prisms (including cubes), and triangular prisms, and describe their attributes using formal geometric language;
- (F) compose two-dimensional shapes by joining two, three, or four figures to produce a target shape in more than one way if possible;
- (G) partition two-dimensional figures into two and four fair shares or equal parts and describe the parts using words; and
- (H) identify examples and non-examples of halves and fourths.
