# Common Core Standards for High School Mathematics

By Amitra Schwols; Kathleen Dempsey et al. | Go to book overview

CHAPTER 3
Algebra
In this chapter, we’ll examine the high school mathematics standards in the conceptual category of Algebra, again discussing the content by domain. For each domain, we will first give an overview of how the domain relates to the other domains in Algebra and how the contents of the domain relate to the Standards for Mathematical Practice. We will then look at each cluster within the domain, identifying the connections among each cluster’s content and describing how the content differs and builds across grades and conceptual areas. This close analysis is aimed at clarifying the meaning and developmental progression of each standard within the context of the entirety of the Common Core standards for mathematics.The Algebra category (HSA) is subdivided into the following domains:
 • Seeing Structure in Expressions (HSA-SSE) • Arithmetic with Polynomials and Rational Expressions (HSA-APR) • Creating Equations (HSA-CED) • Reasoning with Equations and Inequalities (HSA-REI)

Taken together, these domains are designed to help students understand, create, and manipulate expressions, equations, and inequalities. The first two domains focus on expressions; the last two, on equations and inequalities.
