Standard Identifier: 5.OA.2.1

Grade: 5
Domain: Operations and Algebraic Thinking

Cluster:
Write and interpret numerical expressions.

Standard:
Express a whole number in the range 2–50 as a product of its prime factors. For example, find the prime factors of 24 and express 24 as 2 × 2 × 2 × 3. CA

Standard Identifier: 5.OA.3

Grade: 5
Domain: Operations and Algebraic Thinking

Cluster:
Analyze patterns and relationships.

Standard:
Generate two numerical patterns using two given rules. Identify apparent relationships between corresponding terms. Form ordered pairs consisting of corresponding terms from the two patterns, and graph the ordered pairs on a coordinate plane. For example, given the rule “Add 3” and the starting number 0, and given the rule “Add 6” and the starting number 0, generate terms in the resulting sequences, and observe that the terms in one sequence are twice the corresponding terms in the other sequence. Explain informally why this is so.

Standard Identifier: G-CO.1

Grade Range: 7–12
Domain: Congruence
Discipline: Math I
Conceptual Category: Geometry

Cluster:
Experiment with transformations in the plane.

Standard:
Know precise definitions of angle, circle, perpendicular line, parallel line, and line segment, based on the undefined notions of point, line, distance along a line, and distance around a circular arc.

Standard Identifier: G-CO.12

Grade Range: 7–12
Domain: Congruence
Discipline: Math I
Conceptual Category: Geometry

Cluster:
Make geometric constructions. [Formalize and explain processes.]

Standard:
Make formal geometric constructions with a variety of tools and methods (compass and straightedge, string, reflective devices, paper folding, dynamic geometric software, etc.). Copying a segment; copying an angle; bisecting a segment; bisecting an angle; constructing perpendicular lines, including the perpendicular bisector of a line segment; and constructing a line parallel to a given line through a point not on the line.

Standard Identifier: G-CO.13

Grade Range: 7–12
Domain: Congruence
Discipline: Math I
Conceptual Category: Geometry

Cluster:
Make geometric constructions. [Formalize and explain processes.]

Standard:
Construct an equilateral triangle, a square, and a regular hexagon inscribed in a circle.

Standard Identifier: G-CO.2

Grade Range: 7–12
Domain: Congruence
Discipline: Math I
Conceptual Category: Geometry

Cluster:
Experiment with transformations in the plane.

Standard:
Represent transformations in the plane using, e.g., transparencies and geometry software; describe transformations as functions that take points in the plane as inputs and give other points as outputs. Compare transformations that preserve distance and angle to those that do not (e.g., translation versus horizontal stretch).

Standard Identifier: G-CO.3

Grade Range: 7–12
Domain: Congruence
Discipline: Math I
Conceptual Category: Geometry

Cluster:
Experiment with transformations in the plane.

Standard:
Given a rectangle, parallelogram, trapezoid, or regular polygon, describe the rotations and reflections that carry it onto itself.

Standard Identifier: G-CO.4

Grade Range: 7–12
Domain: Congruence
Discipline: Math I
Conceptual Category: Geometry

Cluster:
Experiment with transformations in the plane.

Standard:
Develop definitions of rotations, reflections, and translations in terms of angles, circles, perpendicular lines, parallel lines, and line segments.

Standard Identifier: G-CO.5

Grade Range: 7–12
Domain: Congruence
Discipline: Math I
Conceptual Category: Geometry

Cluster:
Experiment with transformations in the plane.

Standard:
Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using, e.g., graph paper, tracing paper, or geometry software. Specify a sequence of transformations that will carry a given figure onto another.

Standard Identifier: G-CO.6

Grade Range: 7–12
Domain: Congruence
Discipline: Math I
Conceptual Category: Geometry

Cluster:
Understand congruence in terms of rigid motions. [Build on rigid motions as a familiar starting point for development of concept of geometric proof.]

Standard:
Use geometric descriptions of rigid motions to transform figures and to predict the effect of a given rigid motion on a given figure; given two figures, use the definition of congruence in terms of rigid motions to decide if they are congruent.
