**Subject Area:**Mathematics

**Grade:**7

**Domain-Subdomain:**Geometry

**Cluster:**Level 2: Basic Application of Skills & Concepts

**Cluster:**Draw, construct, and describe geometrical figures and describe the relationships between them. (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 :**

Given conditions should not focus on similarity or congruence or that the sum of angles in a triangle is 180 degrees. Be aware of the scoring capabilities for the GRID tool when designing these items. To distinguish from other grades, conditions should include factors other than parallel/perpendicular lines and angle measure, such as symmetry and side length.**Calculator :**Neutral

**Context :**Allowable

**Test Item #:**Sample Item 1**Question:**Use the Connect Line tool to draw a figure that has at least one pair of parallel sides and two side lengths of 5 units and 7 units.

**Difficulty:**N/A**Type:**GRID: Graphic Response Item Display

**Test Item #:**Sample Item 2**Question:**Nathan wants to draw a triangle. He knows that two of the side lengths are 5 inches and 7 inches.What is a possible length for the third side?

**Difficulty:**N/A**Type:**EE: Equation Editor

**Test Item #:**Sample Item 3**Question:**Use the Connect Line tool to draw a quadrilateral that has exactly two lines of symmetry.

**Difficulty:**N/A**Type:**GRID: Graphic Response Item Display

## Virtual Manipulative

This manipulative is a virtual realization of the kind of physical experience that might be available to students given three pieces of straws and told to make them into a triangle. when working with pieces that determine unique triangles (SSS, SAS, ASA). Students construct triangles with the parts provided. After building a red and a blue triangle, students can experience congruence by actually moving one on the top of the other.
