111.4.b.8

(8) 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) create two-dimensional shapes based on given attributes, including number of sides and vertices;

• (B) classify and sort three-dimensional solids, including spheres, cones, cylinders, rectangular prisms (including cubes as special rectangular prisms), and triangular prisms, based on attributes using formal geometric language;

• (C) classify and sort polygons with 12 or fewer sides according to attributes, including identifying the number of sides and number of vertices;

• (D) compose two-dimensional shapes and three-dimensional solids with given properties or attributes; and

• (E) decompose two-dimensional shapes such as cutting out a square from a rectangle, dividing a shape in half, or partitioning a rectangle into identical triangles and identify the resulting geometric parts.
