Standard Identifier: 7.RP.2.a

Grade: 7
Domain: Ratios and Proportional Relationships

Cluster:
Analyze proportional relationships and use them to solve real-world and mathematical problems.

Standard:
Recognize and represent proportional relationships between quantities. Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.

Standard Identifier: 7.RP.2.b

Grade: 7
Domain: Ratios and Proportional Relationships

Cluster:
Analyze proportional relationships and use them to solve real-world and mathematical problems.

Standard:
Recognize and represent proportional relationships between quantities. Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.

Standard Identifier: 7.RP.2.c

Grade: 7
Domain: Ratios and Proportional Relationships

Cluster:
Analyze proportional relationships and use them to solve real-world and mathematical problems.

Standard:
Recognize and represent proportional relationships between quantities. Represent proportional relationships by equations. For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t = pn.

Standard Identifier: 7.RP.2.d

Grade: 7
Domain: Ratios and Proportional Relationships

Cluster:
Analyze proportional relationships and use them to solve real-world and mathematical problems.

Standard:
Recognize and represent proportional relationships between quantities. Explain what a point (x, y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, r) where r is the unit rate.

Standard Identifier: 7.RP.3

Grade: 7
Domain: Ratios and Proportional Relationships

Cluster:
Analyze proportional relationships and use them to solve real-world and mathematical problems.

Standard:
Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.

Standard Identifier: 8.EE.1

Grade: 8
Domain: Expressions and Equations

Cluster:
Work with radicals and integer exponents.

Standard:
Know and apply the properties of integer exponents to generate equivalent numerical expressions. For example, 3^2 × 3^-5 = 3^-3 = 1/3^3 = 1/27.

Standard Identifier: 8.EE.2

Grade: 8
Domain: Expressions and Equations

Cluster:
Work with radicals and integer exponents.

Standard:
Use square root and cube root symbols to represent solutions to equations of the form x^2 = p and x^3 = p, where p is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that √2 is irrational.

Standard Identifier: 8.EE.3

Grade: 8
Domain: Expressions and Equations

Cluster:
Work with radicals and integer exponents.

Standard:
Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other. For example, estimate the population of the United States as 3 × 10^8 and the population of the world as 7 × 10^9, and determine that the world population is more than 20 times larger.

Standard Identifier: 8.EE.4

Grade: 8
Domain: Expressions and Equations

Cluster:
Work with radicals and integer exponents.

Standard:
Perform operations with numbers expressed in scientific notation, including problems where both decimal and scientific notation are used. Use scientific notation and choose units of appropriate size for measurements of very large or very small quantities (e.g., use millimeters per year for seafloor spreading). Interpret scientific notation that has been generated by technology.

Standard Identifier: 8.EE.5

Grade: 8
Domain: Expressions and Equations

Cluster:
Understand the connections between proportional relationships, lines, and linear equations.

Standard:
Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.
