Grade 2 - Shape and Space

Standard 2.SS.4 - Compare and identify similar or different two dimensional shapes.

Included Skills:

Describe, compare, and construct 2-D shapes, including:
• triangles
• squares
• rectangles
• circles.
• Identify examples of triangles, rectangles, squares, and circles as found in personal experiences.
• Compare the attributes of triangles, squares, rectangles, and circles and generalize descriptions of each category of 2-D shapes objects.
• Critique the statement "A 2-D shape can either be a rectangle or a square, but not both".
• Compare two 2-D shapes of the same type (e.g., both are circles) and explain how the dimensions of the shapes can be used to compare the shapes (one-to-one correspondence or non-standard units).
• Classify 2-D shapes arranged in different orientations according to the type (triangle, rectangle, square, or circle) and explain the impact of the orientation of shape on its classification.
• Create a model to represent a 2-D shape.
• Sort regular and irregular 2-D shapes according to two attributes and explain the sorting rule used.
