# 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.

## Look for and express regularity in repeated reasoning.

Mathematically proficient students notice if calculations are repeated, and look both for general methods and for shortcuts.

## Look for and make use of structure.

Mathematically proficient students look closely to discern a pattern or structure.

## Attend to precision.

Mathematically proficient students try to communicate precisely to others.

## Use appropriate tools strategically.

Mathematically proficient students consider the available tools when solving a mathematical problem.

## Model with mathematics.

Mathematically proficient students can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace.

## Construct viable arguments and critique the reasoning of others.

Mathematically proficient students understand and use stated assumptions, definitions, and previously established results in constructing arguments. They make conjectures and build a logical progression of statements to explore the truth of their conjectures.

## Reason abstractly and quantitatively.

Mathematically proficient students make sense of quantities and their relationships in problem situations.

## Make sense of problems and persevere in solving them.

Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals.

## Standards for Mathematical Practice Introduction

The Standards for Mathematical Practice describe varieties of expertise that mathematics educators at all levels should seek to develop in their students.
