# Common Core

The Common Core State Standards Initiative is a state-led effort coordinated by the National Governors Association Center for Best Practices (NGA Center) and the Council of Chief State School Officers (CCSSO). The standards were developed in collaboration with teachers, school administrators, and experts, to provide a clear and consistent framework to prepare our children for college and the workforce.

## Solving Equations

CC.9-12.A.REI.1 – Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution. Construct a viable argument to justify a solution method.

## Solve Linear Formulas and Literal Equations For a Specified Variable

CC.9-12.A.CED.1 & CC.9-12.A.REI.3 – Create equations and inequalities in one variable and use them to solve problems.

## Solving and Graphing Absolute Value Inequalities

CC.9-12.A.CED.1 – Create equations and inequalities in one variable and use them to solve problems.

## Solve and Graph Simple Absolute Value Equations and Inequalities

CC.9-12.A.CED.1 – Create equations and inequalities in one variable and use them to solve problems.

## Identify Independent Variable and Dependent Variable on Various Representational Modes: Words, Symbols, and/or Graphs

CC.9-12.A.CED.1 – Create equations and inequalities in one variable and use them to solve problems.

## Independent and Dependent Variable

CC.9-12.A.CED.1 – Create equations and inequalities in one variable and use them to solve problems.

## Identifying Independent and Dependent Variables

CC.9-12.A.CED.1 – Create equations and inequalities in one variable and use them to solve problems.

## Identifying Variables: Independent and Dependent

CC.9-12.A.CED.1 – Create equations and inequalities in one variable and use them to solve problems.

## Simplify Expressions by Factoring

CC.9-12.A.APR.7 – Understand that rational expressions form a system analogous to the rational numbers, closed under addition, subtraction, multiplication, and division by a nonzero rational expression; add, subtract, multiply, and divide rational expressions.

## Simplify Algebraic Fractions by Factoring 2

CC.9-12.A.APR.7 – Understand that rational expressions form a system analogous to the rational numbers, closed under addition, subtraction, multiplication, and division by a nonzero rational expression; add, subtract, multiply, and divide rational expressions.
