Standard Identifier: 7.EE.1

Grade: 7
Domain: Expressions and Equations

Cluster:
Use properties of operations to generate equivalent expressions.

Standard:
Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.

Standard Identifier: 7.EE.2

Grade: 7
Domain: Expressions and Equations

Cluster:
Use properties of operations to generate equivalent expressions.

Standard:
Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related. For example, a + 0.05a = 1.05a means that “increase by 5%” is the same as “multiply by 1.05.”

Standard Identifier: 7.EE.3

Grade: 7
Domain: Expressions and Equations

Cluster:
Solve real-life and mathematical problems using numerical and algebraic expressions and equations.

Standard:
Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. For example: If a woman making $25 an hour gets a 10% raise, she will make an additional 1/10 of her salary an hour, or $2.50, for a new salary of $27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation.

Standard Identifier: 7.EE.4.a

Grade: 7
Domain: Expressions and Equations

Cluster:
Solve real-life and mathematical problems using numerical and algebraic expressions and equations.

Standard:
Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these forms fluently. Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. For example, the perimeter of a rectangle is 54 cm. Its length is 6 cm. What is its width?

Standard Identifier: 7.EE.4.b

Grade: 7
Domain: Expressions and Equations

Cluster:
Solve real-life and mathematical problems using numerical and algebraic expressions and equations.

Standard:
Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. Solve word problems leading to inequalities of the form px + q > r or px + q < r, where p, q, and r are specific rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem. For example: As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100. Write an inequality for the number of sales you need to make, and describe the solutions.

Standard Identifier: A-APR.1

Grade Range: 7–12
Domain: Arithmetic with Polynomials and Rational Expressions
Discipline: Algebra I
Conceptual Category: Algebra

Cluster:
Perform arithmetic operations on polynomials. [Linear and quadratic]

Standard:
Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials.

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.
