**Subject Area:**Mathematics

**Grade:**4

**Domain-Subdomain:**Geometry

**Cluster:**Level 1: Recall

**Cluster:**Draw and identify lines and angles, and classify shapes by properties of their lines and angles. (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.

**Assessment Limits :**

s Items may not require students to name a given figure. Items may not require knowledge or use of ordered pairs or a defined coordinate grid system. Items may require students to draw a figure based on multiple attributes (e.g., an acute triangle), with the exception of right triangles. Items that include trapezoids must consider both the inclusive and exclusive definitions. Items may not use the term "kite" but may include the figure.**Calculator :**No

Students are asked to identify right, acute, and obtuse angles in a two-dimensional figure, and explain the differences among these types of angles.

Students are asked to draw parallel lines, perpendicular lines, a point, and a line segment. Students also explain how a line segment is different from a ray or line.

Students locate points, lines, line segments, and rays in a given diagram.

Students are asked to identify parallel and perpendicular sides and explain how they know.
