Showing 1 - 10 of 16 Standards

Standard Identifier: N-RN.1

Grade Range: 7–12
Domain: The Real Number System
Discipline: Algebra I
Conceptual Category: Number and Quantity

Cluster:
Extend the properties of exponents to rational exponents.

Standard:
Explain how the definition of the meaning of rational exponents follows from extending the properties of integer exponents to those values, allowing for a notation for radicals in terms of rational exponents. For example, we define 5^1/3 to be the cube root of 5 because we want (5^1/3)^3 = 5(^1/3)^3 to hold, so (5^1/3)^3 must equal 5.

Grade Range: 7–12
Domain: The Real Number System
Discipline: Algebra I
Conceptual Category: Number and Quantity

Cluster:
Extend the properties of exponents to rational exponents.

Standard:
Rewrite expressions involving radicals and rational exponents using the properties of exponents.

Standard Identifier: N-RN.3

Grade Range: 7–12
Domain: The Real Number System
Discipline: Algebra I
Conceptual Category: Number and Quantity

Cluster:
Use properties of rational and irrational numbers.

Standard:
Explain why the sum or product of two rational numbers is rational; that the sum of a rational number and an irrational number is irrational; and that the product of a nonzero rational number and an irrational number is irrational.

Standard Identifier: G-CO.1

Grade Range: 8–12
Domain: Congruence
Discipline: Geometry
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.10

Grade Range: 8–12
Domain: Congruence
Discipline: Geometry
Conceptual Category: Geometry

Cluster:
Prove geometric theorems. [Focus on validity of underlying reasoning while using variety of ways of writing proofs.]

Standard:
Prove theorems about triangles. Theorems include: measures of interior angles of a triangle sum to 180°; base angles of isosceles triangles are congruent; the segment joining midpoints of two sides of a triangle is parallel to the third side and half the length; the medians of a triangle meet at a point.

Standard Identifier: G-CO.11

Grade Range: 8–12
Domain: Congruence
Discipline: Geometry
Conceptual Category: Geometry

Cluster:
Prove geometric theorems. [Focus on validity of underlying reasoning while using variety of ways of writing proofs.]

Standard:
Prove theorems about parallelograms. Theorems include: opposite sides are congruent, opposite angles are congruent, the diagonals of a parallelogram bisect each other, and conversely, rectangles are parallelograms with congruent diagonals.

Standard Identifier: G-CO.12

Grade Range: 8–12
Domain: Congruence
Discipline: Geometry
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: 8–12
Domain: Congruence
Discipline: Geometry
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: 8–12
Domain: Congruence
Discipline: Geometry
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: 8–12
Domain: Congruence
Discipline: Geometry
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.
