Recognize and draw shapes (triangles, quadrilaterals, pentagons, hexagons) having specified attributes (e.g., number of angles, sides or faces). (2.G.1)
Concepts and Skills
* Recognize and draw two-dimensional shapes with specified attributes
Identify and describe three dimensional figures (spheres, cylinders, rectangular prisms, cones, pyramids)
Create and complete two-dimensional symmetric shapes or designs
Draw line segments and identify parallel line segments
A student in 2nd grade can demonstrate the ability to apply and comprehend critical language by describing the important attributes of shapes.
Analyzing the characteristics and properties of shapes leads to generalizations about geometric relationships.
Shapes and patterns are all around us.
