This exemplar has been developed to guide high school students and instructors with Common Core standards for Math.
Algebraic manipulations are governed by the properties of operations and exponents, and the conventions of algebraic notation. At times, an expression is a result of applying operations to simpler expressions. Viewing an expression as the result of operations on simpler expressions can sometimes clarify its underlying structure.
This high school exemplar is intended to extend and connect students’ understandings from middle school to polynomials. It focuses on reinforcing knowledge and skills, rather than developing completely new knowledge and skills.
