Identify two-dimensional shapes, such as rhombuses, pentagons, hexagons, octagons, and ovals, as well as equilateral, isosceles, and scalene triangles.
Clarifications:

#### Essential Understandings

Concrete:

• Recognize a two-dimensional shape (know that this:   is not a shape).
• Count the number of sides of a two-dimensional shape manipulative and name the shape based on the number of sides.
• Count the angles of two-dimensional shape manipulative and name the shape based on the number of angles.
• Recognize flat objects as two-dimensional and objects with length, height, and width as three-dimensional.
Representation:
• Given a visual representation of two-dimensional shapes, count the number of sides and name the shape based on the number of sides.
• Given a visual representation of two-dimensional shapes, count the number of angles and name the shape based on the number of angles.
• Understand the following concepts and vocabulary of two-dimensional, rhombus, pentagons, hexagons, angles, and sides.

Cluster: Reason with shapes and their attributes. (Additional Cluster)

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
